28944RP Speed Queen Washer Upper or Lower Bearing â˘is a replacement âbearing component designed to support the ârotating elements of a Speed Queen washingâ machine. As a bearing, its primary function is to provide low-friction rotary⤠support and maintain axial â˘and radial alignment⤠between the spin basket, inner tub,â and the âdrive â˘shaft â˘or transmission interface; the service part designation “upper âŁor lower” indicates its request location within the tub assembly depending on the model and chassisâ layout.
Inside the appliance the â¤bearing⤠interfaces directly with the inner tub⢠and drive shaft (or transmission⢠output)and works in concert with seals, âbearing housingsand the suspension system to allow high-speed rotation during spin and to carry both âradial âloads from â˘the âbasket mass and âaxial loads from unbalanced loads. Proper â˘bearing performance is integral to⣠spin efficiency, noise control and preventing tub movement; when bearings degrade they âcan compromise âshaftâ alignment, damage seals,â permit water ingress to the⤠gearbox or transmission areaand accelerate wear on adjacent components.
This article will describe the bearing’s detailed function and âŁtypical configurations for Speed Queen top-load models,outline compatibility and part-number verification steps,identify common failure â¤symptoms (noise during spin,excessive⤠vibration or play,visible leaks,metal debris),present diagnosticâ and troubleshooting procedures,and âdiscuss replacement considerations such as distinguishing upper versus lower installations,required âtools âand techniques for press-fit removal and installation,seal and lubricant replacement,and â¤criteria for replacing related â¤components (shaft,tub,or bearing housing)â toâ ensure a durable repair.

Function and Role âŁofâ the 28944RP Bearing inâ Speed âQueen Washer⣠Drum Support and Vibration Control
Theâ 28944RP Speedâ Queen Washer Upperâ or â˘Lower Bearing is a precision bearing element⤠that âŁsupports the washer drum assembly and⢠maintains âconcentric rotation under the high radial and occasionalâ axial loads generated during spinâ cycles.In Speed Queen top-load and front-load âdesigns that accept â¤this part â˘number, the same bearing geometry can be used in â¤either an upper or lower position depending on the model’s⤠tub support architecture; however, the load conditions differ – the⢠lower position⢠typically âendures higher radial load andâ moisture exposure, while the upper position primarily provides alignment â˘andâ axial restraint. The bearing’s internal âclearance, seal âdesignand lubrication âdetermine its friction characteristics and service life,⢠so⣠matching the bearing to the machine’s shaft diameter, race seatingand seal requirements is critical for âreliable operation.
From a vibration-control viewpoint, the 28944RP contributes to âdrum â˘stability by minimizing runout and damping transient movement between the drum âŁand âthe âŁouter tub. Worn orâ corroded bearings increase eccentricity and generate characteristic symptoms âsuch âas metallic grinding during high-speed spin, progressive wobbleand⣠accelerated wear on suspension elements and seals; replacing theâ bearingâ and⤠associated seals typically restores âconcentricity⣠and reduces transmitted vibration. Proper replacement practice includes pressing theâ bearing⣠into the tub or carrier â˘to the specified depth, verifying shaft and race tolerancesand replacing retaining hardwareâ and seals to prevent water ingress that leads toâ premature failure.
- Common failure symptoms: grinding noise, increased vibration, visible wobble during spin.
- Key replacement checks: shaft runout, housing bore condition, seal integrity.
- Installation note: use a bearing press and replace associated seals andâ snap rings.

How â˘the 28944RP Speed Queenâ Washer Upper or Lower Bearing Operates Within the Tub,seal and Drive Assembly
The 28944RP speed Queen Washer⤠Upper âŁor âŁLower Bearing providesâ the rotating⣠support that allows the inner tub to â¤spin concentricallyâ within the outer cabinet while isolatingâ the drive forces transmitted through⢠the shaft âand coupling. In typical Speed Queen direct-drive assemblies this bearing is a sealed, grease-lubricated unit âpressed intoâ a housing in either the upper or lower âtub support; it carries radial loads from the weight of the tub and wet load andâ resists modest âŁaxial thrust from off-center loads. The bearing worksâ together with the tub seal to keep lubricant inboard and water outboardand technicians should verify model compatibility and housing dimensions before⤠installation because â˘the same part number is intended for specific Speed Queen â˘housings and may be used in either âan upper or a lower position âdepending on the model âconfiguration.
Within⣠the tub, seal and drive assembly the bearing establishes â˘the rotational axis and minimizes runout so⢠the tub remains balanced under spin. The â˘drive shaft transmits âtorque through couplers or splines while the bearing absorbsâ the âresulting radial forces and dampens vibration; the adjacent seal prevents corrosive wash water from âcontaminating the grease and the⢠bearing surface. Typical failure modes include increased noise,⢠measurable axial or radial play, lubricant contamination from a failed seal,â andâ accelerated wear from shaft â¤scoring-symptoms that should prompt bearing âand seal âreplacement together.During service, â¤bearings are installed âwith a controlled press fit, shaft inspected for scoringand housings checked for alignment â¤to⢠ensure the new bearing performs reliably.
- Common symptoms: grinding or rumbling ânoise, tub wobble, leaksâ at the seal, heat buildup at bearing⢠area.
- Service tip: always replaceâ the seal⤠andâ inspect the shaft and housingâ bore when changing the bearing.

Common Failure Symptoms,â Lubrication Issuesâ and Wear Indicators for 28944RPâ Bearings
The 28944RP Speed Queen Washer Upper or⢠Lower Bearing is a precision press-fit bearing used to support theâ washer’s inner tub and spindle assembly, carryingâ both âradial and axial loads generated during agitation and high-speed spin. When functioning correctly⢠the bearing⣠maintains concentric rotation and minimizes shaftâ deflection; when it deteriorates the most âcommon mechanical behaviorsâ are increased drum runout, metal-to-metal noise under loadand progressive⣠heat generation at the hub.Compatibility-wise, this bearing mustâ match the washer’s shaft â¤diameter and the housing bore; improper â¤fit or a mismatched seal âŁcan accelerate wear even if the bearing element âitselfâ is properly specified.
- Loud⢠grinding or growling during spin, frequently⢠enough âŁworse at high RPM.
- Visible drum wobble or side-to-sideâ play when the basket is rocked by hand.
- Oily or gritty residue at the seal or âŁin the tub area (water-entrained grease).
- Localized⢠overheating at the hub or a burnt-grease odor after operation.
- Metal particles⣠in the grease or⣠filter trap indicating materialâ degradation.
Lubrication breakdown and seal failure are the primary causes of premature bearing wear; water intrusion, detergent âdilution,â or high heat can wash out or chemically âdegrade grease, leaving the rolling elements⢠metal-on-metal. Technicians should correlate symptoms with âoperationalâ context – for example, noise only during spin suggests outer âŁrace or roller degradation under centrifugal load, whereas constant noise at all speeds more frequently enough â¤indicates contamination or â˘severe bearing cage⣠damage.Practical inspection includes checking for radial/axial play, â¤smelling for burnt lubricantand examining âgrease for discoloration or metal filings; âas these bearings are âŁtypically a press-fit â˘componentâ in the tub or shaft assembly, replacement of âthe bearing and its seal is the âcommon corrective action rather than attemptingâ re-lubrication in situ.
| Item | Description |
|---|---|
| Axial/radial play | Excess movementâ of the âtub⢠onâ the⤠shaft, frequently enough measurable and correlated âŁwith ânoise and uneven wear. |
| Grease condition | Darkened, watery,⢠or metallic-flecked grease indicates contamination or âŁthermal breakdown. |
| Operational heat | Elevated hub â˘temperature after a spin cycle suggests increased friction due to loss of lubrication or damaged rollers. |
Compatibility, â˘Replacement Considerations and Installation Best Practices for âŁ28944RP Bearings
The 28944RP Speed Queen Washer Upper orâ Lower Bearing provides radial support for the tub assembly and absorbs both âradial and lightâ axial loads produced during spin cycles. In practice this component keeps the inner tub concentric with the drive assembly, reducing vibration⢠andâ wear on the shaft,⢠sealand mounting â¤surfaces. Technicians should treat⤠this bearing⢠as a precision press-fit âcomponent: âŁcorrect fit, clean contact⣠surfacesand compatible seal type determineâ whether the part will functionâ reliably in a given â˘Speed Queen top-load chassis. â˘Confirm fitment by checking âbore âdiameter, outer diameterand overall width â¤against the washer’sâ service âmanual or âmeasured âhousing/shaft dimensions âŁbefore installing a âreplacement, as the same part number âcan appear in differentâ service positions depending on model revision.
- Symptoms that suggest replacement: loud rumbling orâ grinding âduring spin, wobble of the⢠inner tub, visible grease leakage â˘or corroded⣠seals.
- Pre-replacementâ checks: inspect the shaft for scoring, check seal lips and âhousing for corrosionand verify that⢠the mounting bores are not ovalized.
- Installation considerations: bearings are typicallyâ pressed in; avoid â¤hammering the bearing âŁrace directly and replace sealing elements simultaneously to prevent premature failure.

During installation, use controlled assembly methods: an arbor press or hydraulic press with an appropriate bearingâ driver prevents distortion âof races and âseals. If interference fits are required, heat the âhousing (or cool the bearing) to minimize insertion force ârather than striking â¤the bearing;⣠ensure any retaining â¤clips, snap ringsor shoulders areâ clean and undamaged so the component seatsâ fully. After fitting, rotate the tub by hand to detect roughness and check axial play; reassemble seals and fastenersâ to manufacturer torque values and run a low-speed spin check⣠to verify quietâ operation and âŁcorrect alignment before⣠returning the machine to service.
Q&A
What is âthe 28944RP Speed Queen Washer bearing?
28944RP is an OEM replacement âbearing sold for Speed Queen washers.Itâ is indeedâ a radial bearing used to⤠support and allow smooth â˘rotation âof the inner tub/hub assembly.the same basic part number might potentially be sold for âan “upper” or⢠“lower” location depending on the specific model and assembly; always confirm fit by washer model number or by comparing âŁthe old part.
How do I know whether I need the upper or âlower bearing?
âUpperââ and⢠âlowerââ describe the position in the tub assembly.â The⤠lower bearing supports the âbottomâ of the inner tub/hub near âthe drive shaft; the âŁupper bearing supports the top/inner âsection where the âagitator or inner tub connects. Check the service manual or remove the seal/cover⢠to visually identify⤠which âbearing is worn. If you âare unsure, â˘match â¤the physical dimensions of the worn part to the replacement or confirm with the appliance model number when ordering.
What are the âcommon symptoms of a failing upper or lower bearing?
Common signs include loud rumbling or grinding⤠during spin, excessive vibration or wobble, knocking⣠noises as the tub rotatesand sometimes water leaking fromâ the âŁtub seal area. A worn bearing often produces noise that changes with spin speed and⤠may be louder when the âwasher is loaded.
Canâ I replace just one bearingor should I replace both at theâ same time?
If⣠the washer has⢠both anâ upper âand lower bearing and one has failed, it’s good practice to inspect âŁand⤠usually replace âboth bearings and the âtub seal(s) at the⢠same â˘time. âŁBearings â¤that are the same age have similar wearand⢠replacing only the failed âunit often leads âto premature⢠failureâ of the remaining bearing. Also replaceâ the ârubber seal(s)⢠and any damaged hub components.
What⢠tools and equipment are required â¤to replace âthe 28944RP bearing?
Typical tools: socket/wrench set,⤠screwdrivers, pliers, bearing puller â¤or slide âŁhammer (to remove old bearings), hydraulic or⢠arbor press (to install ânew bearings), seal driver orâ appropriate⤠sized socket, mallet, penetrating oil, cleaning suppliesand safety gear. A bearing press âis stronglyâ recommended to avoid damaging the new bearing.â Ifâ you don’t own the correct tools or have no experience pressing bearings, consider âa repair âŁshop.
How tough is the replacement and âhow long does it take?
difficulty is moderate to âhigh. âThe job usually requires removing the washer cabinet or top, disassembling the agitator/inner tub,â separating the âouter tub, âand pressing out/in bearings and seals.â For a competent technician it can take 2-4 hours; for a DIYer without experience or proper tools it will take longer â˘and carries risk of damaging âthe tubâ or new⤠bearing. Unplug and turn â˘off⣠water before starting.
Any special tips to ensure â˘a⤠long-lasting bearing installation?
Key tips: â˘always replace the tubâ seal(s) â˘when installing new bearings;â thoroughly âclean â˘and inspect the bearing bore and hubâ for corrosion or pitting and replace the hub if⢠damaged; press bearings straightâ and to theâ correct depth âusingâ a proper press or driver;â do ânot hammer bearings directly; âŁpack bearings with appropriate grease if âŁrequired (follow OEM instructions); avoid⣠overheating bearings when using heat-use controlled, even heat âif necessary; and follow torque and reassembly âprocedures from the Speed Queen service manual.
Should I âŁuse aftermarket⣠bearings or stick â¤with OEM â28944RP?
OEM bearings like 28944RP are engineered âŁtoâ match the washer’sâ tolerances and seals. Aftermarket bearings can be⣠acceptable if theyâ are an⤠exact dimensional and material match and â¤include compatible seals. However,â to minimize ârisk of fitment or longevity problems, most technicians recommendâ using the OEM part or a high-quality equivalent and replacing the âŁtub seals andâ any related hardware at the⢠same time.
in summary
The 28944RP Speed⣠Queen âwasher upperâ or lower bearing plays a essential role in supporting the âtub and drum assembly, maintaining alignment, âŁand enabling smooth, low-friction⤠rotation under load. Properly functioning bearings⤠reduce noise and vibration, limit wear âŁon adjacent components such as shafts and sealsand contribute directly to the washer’s operational stability and longevity. Becauseâ these bearings carry both radial and axial loads during⣠wash and spin cycles, âŁtheir condition â¤has a direct effect on performance and long-term reliability.
Timely and accurate â˘diagnosis âfollowed by correct⢠replacement âwhen necessary protects the appliance from progressive damage and âmore costly repairs.
