The WE3X87 âGE rear Drum Slide Bearing is a â˘rear drum slide bearing used on GE tumble dryers âŁto âsupport the rear ofâ the rotating⣠drum. As âŁaâ sliding bearing (a low-friction contact surface rather than a⤠rolling element), the â¤component provides âa wear surface against which the drum rear shaft or⢠hub glides; it is typically molded from a durable polymer âorâ composite material⣠and is mounted in the dryer rear bulkheadâ or⤠bearing âplate.
Inside the âappliance the â˘slide bearing’s primary⤠roleâ is to⢠maintain drum alignment and reduce friction between the rotating drum and the stationary ârear support structure. It interfaces directly with the drum hub or shaftand âindirectly affects the âbelt drive, âŁmotor⣠load, âdrum seals and lint-management paths. Proper function of the⤠slideâ bearingâ helps preserve belt⤠tension, minimizes axial and radial runout, prevents metal-to-metal contact that can score the drumand reduces noiseâ and heat âŁgeneration during normal⢠operation.

Function and mechanical Role of the Rear⣠Drum Slide Bearing in GE Laundry Dryers
The WE3X87 GE â˘Rear Drum Slide Bearing â¤is a stationary sliding surface that âŁsupports the rear of the dryer âŁdrum and preserves âconcentric alignment between the rotating drum and the bulkhead. Unlike a ârolling-element bearing, this part provides a broad, low-friction⤠contact face-commonly âmolded polymer or a⤠bronze-lined insert-that controls radial clearance, dampens vibrationand prevents metal-to-metal contact that can generate heat and accelerate wear. In practical use, a⤠worn or damaged slide bearing âmanifests as drum wobble, scraping or squealing noises, âuneven ârotationâ and premature belt or idler wear; these behaviors⤠are â¤symptomatic of increased radial play or scoredâ bearing âfaces rather âŁthan â˘electrical or motor faults.
- Symptoms to check: scraping noise, visible scoring on theâ bearing or⣠shaft, âexcessive drum runoutand rapid belt deterioration.
- Installation/compatibility:â verify bore diameter, flange dimensions âŁand locating âŁfeatures âagainst the drum housing âbefore fitting â˘a replacement.
- Service action: measure shaft and â˘bearing â˘face, âreplace the bearing if âthe slidingâ surface shows âŁgrooves or wear beyond a âŁfew tenths of a millimeterand recondition or replace the âshaft if scored.
Mechanically, the bearing is pressed or âretained inâ the rear bulkhead and relies on correct shaft finish âand axial preload to maintain⤠stableâ operation; insufficient contact â˘area or⢠incorrect geometry will alter drum alignment and quickly reproduce â˘the fault. For⤠technicians, the practical checklist is dimensionalâ verification, inspection for surface damage,⢠and âensuring the replacement matches the âoriginal locating features-procedures that limit rework and reduce â˘collateral wear to belts, idlers and the drum shell.
| Item | Description |
|---|---|
| Fitment | Direct-replacement geometry required; confirm bore, flange and locating tab dimensions against the dryer model. |
| Material | Molded polymer composite or bronze-lined sliding face âchosen for low friction and wear resistance. |
| Commonâ symptom | Drum scraping/squeal, increased radial runout, uneven drying and accelerated belt wear. |
How the WE3X87 GE Rear Drum Slide Bearing Integrates with Drum, Shaftand Support systems
The WE3X87 GE Rear Drum slide Bearing â˘provides the â¤rear running surface and alignment for a dryer â¤drum by forming a low-friction interface between the â˘drum’s rear lip and the stationary support/shaft assembly. As a molded âbearing (commonly a nylon or engineered âpolymer bushing), âŁit accepts radial and light âaxial loads from the rotating drum, transfersâ those loads into the cabinet support bracketand maintains concentric clearance to⤠minimize drum runout. Proper seating on the âŁshaft and cleanâ contact surfaces are essential: an âundersized fit allows wobble and noise, while an oversizedâ or⣠damaged bore causes binding and accelerated wear.
- Interfaces: drum rear lip, shaft end âŁor stuband the âcabinet support⢠bracket⤠– each must be⢠inspected for⤠wear before installing the bearing.
- Behavioral signs:â rough rotation, scrapingor lateral play indicate bearing wear or shaft scoring.
- Installation notes: press- âor slip-fit requirementsorientation of the bearing lipand ensuring noâ debris or corrosion on the shaft.
- Compatibility: â¤confirm part number and model fit; âŁdo not substitute different bore/tolerance bearings âŁwithout verifying dimensions.
| Item | Description |
|---|---|
| Material | Engineeredâ polymer⣠(wear-resistant nylon/PAI â˘variants) for lowâ friction âandâ impact resistance |
| Fit type | Typically a slip or lightâ pressâ fit on a stub shaft⢠with a⢠molded⤠outer⣠flange â˘seating against the support bracket |
| Common failure signs | Axial play, scored drum lip, scraping noise, uneven drum rotation |
Inâ service,⤠the bearing’s clearance and wear pattern determine drum tracking and noise âŁcharacteristics: uneven wear⢠will induce oscillation⤠that accelerates adjacent âŁcomponent damage (drum, â˘shaft shoulder,â or support). Technicians should check⤠shaft concentricity, remove any surface corrosion, âand⣠verify the support bracket âŁseat before installing â˘a replacement; aâ correctly installed⢠bearing restores concentric alignment âand reduces heat-generating friction. âIn â˘practical repairs, replace the⢠bearing together with any visibly damaged shaft or support hardware and confirm smooth,â full-rotation by hand before âreassembling the⣠dryer âto prevent repeat failures.
Common Failure Symptoms,â Wear patterns, â¤and Diagnostic Indicators of Drum Slide Bearings
Theâ WE3X87 GE Rear Drum Slide Bearing provides⤠the⣠sliding interface and axial⤠supportâ for the rear edge of a⢠dryer drum, maintaining concentricity and reducing friction between the rotating drum and âthe⢠cabinet âŁback panel. âIn normal operation the slide bearing⣠distributes axial loads from the drum and allows smooth rotation⣠with minimal lateral play; typical designsâ use a low-friction polymer surface bonded to a stamped mounting plate so the replacement part restores original contact geometry âand clearances. âCompatibility is steadfast by the mounting hole pattern âand clearance envelope, so technicians should â¤verify that âŁthe bearing’sâ plate and pad âŁdimensions match the dryer model before installation to avoid altered drum alignment or premature wear⢠of adjacent components (rollers,⢠glidesor the drum âŁrim).
- Scraping or⢠grinding ânoise at âŁspin-up or high RPM
- Visible âscoring or polished grooves on theâ bearing pad or drum â¤edge
- Excessive lateral play or wobble of the drum when rotated by hand
- Localized âheat âdiscolorationâ or âŁmelted polymer on theâ pad
- Metallic debris âor lint accumulation concentrated at the rear drum edge
Diagnosing failure focuses on visualâ inspection and dynamic checks: rotate theâ drum âbyâ hand to feel for roughness and observe runout; âŁuse a dial indicator â¤or straightedge to quantify lateral movement relative to the cabinet (compare to factory service limits).â Wear patterns concentrated â¤on one side of the pad indicate misalignment or a failed roller elsewhere that⢠has shifted load âŁonto the âslide bearing; uniform thinning suggests long-term abrasion. Inâ practical repair scenarios, â¤replace the worn slide bearing when you find⣠scoring⣠that penetrates the â¤low-friction surface, significant axial playor heat⢠damage â˘to the polymer – these⤠conditions accelerate drum rimâ wear andâ can lead to noisy operation or seal failure if left unaddressed.
| Item | Description |
|---|---|
| Surface scoring | Grooves or polished tracks on the pad indicate abrasive contact or foreign debris. |
| Lateral play | Measurable drum movement beyond spec;â suggests pad thinning or fastener looseness. |
| Thermal damage | Discoloration/melting of polymer caused âby excessive frictionâ or sustained loading. |
Replacement Considerations, model â˘Compatibilityand Installation⣠Procedures for the WE3X87 GE Rear âDrum Slide Bearing
The WE3X87 GE Rear Drum Slide Bearing serves as the rear support point for the âdryer drum, controlling axial âposition⤠and providing aâ low-friction surface where â˘the drum contacts the rear â˘bulkhead. Typically molded from a wear-resistant polymer, the bearing transfers radial and axial âŁloads from⤠the rotating drumâ flangeâ into the bulkhead while resisting abrasion from the drumâ shaft. When the bearing degrades-visible as scoring on the mating surfaces,pronounced vibration,or a scraping noise âduring rotation-the drum will show lateral play and uneven wear patterns; these behaviors indicate⢠the bearing no longer maintains concentric alignment⣠and should be replaced rather⣠than adjusted. Compatibility⣠depends on the bearing âpocket geometry, shaft diameterand locating features; confirm physical dimensions âand OEM cross-references âfor the WE3X87 GE âŁRear drum Slide Bearing before purchasing a â˘replacement to avoid fitment and tolerance issuesâ that â˘causeâ accelerated wear or interference with the drum seal.
Replacement requires inspection and planning âofâ both⣠the âŁbulkhead pocketâ and the drum shaft: remove the drum â˘and belt,visually inspect and deburr âthe shaft,and thoroughly clean lint and residue from â¤the pocket to⢠ensure the new bearing seats fully. Press-fit bearings must be installed squarely â¤and drivenâ only until⣠the outer face is flush with the bulkhead;⣠align â˘anyâ retention tabs or orientation âmarks and avoidâ lubricants unless specified by the manufacturer,as â˘some polymers rely⤠on⢠dry-runningâ characteristics. After reassembly, verify freeâ rotation and âminimal âaxial play; if you detect ârubbing or irregular drag, ârecheck seatingâ and shaft condition. Practical checks include measuring shaft runout with calipers orâ a dial indicator and comparing the new bearing bore to â¤the drum flange⤠clearance toâ ensure the installed assembly keeps the drum âconcentric within âspecification.
- Symptoms indicating replacement: scrapingâ noise, visible scoring,â excess lateral play,⢠and âuneven drum rotation.
- Basic âinstallationâ steps: remove drum and belt⤠â clean and âinspect shaft and pocket â press-fitâ the new bearing squarely ââ reassemble âand â¤test rotation.
- Compatibilityâ checkpoints: outer diameter and thickness of bearing, âŁlocating tab⣠position,â and matching OEM âpart⢠number or physical test-fit.

Q&A
What is the WE3X87 GEâ Rear âŁDrumâ Slideâ Bearing and what does it do?
The âWE3X87 is a rear drum âslide bearing (also âcalled⢠a rear drum glide) usedâ on many GE â¤and Hotpoint electric and gas dryers. It is a small molded bearing or glide that mounts to the rear bulkhead; the dryer drum rides â˘against it. Its purpose is to center and support the â¤rear â˘of the drum, reduce friction and noiseand prevent excessive wear on the drum and bulkhead.
What are common⢠symptoms⤠that the rear drum slide bearing⤠is failing?
Typical signs of a worn or failed slide bearing includeâ loud squeaking or squealing during drum rotation, scraping or grinding noises, uneven or â¤jerky⣠drum⣠movement, accelerated belt wear or âfrequent belt breakage, visible scoring orâ wear on the drum â˘rear edgeand in severeâ cases smoke fromâ friction.You may also notice the drum rubbing against âthe ârear bulkhead.
Can I âcontinue to use the dryer if the WE3X87 is damaged?
noâ -⣠it is indeed not ârecommended. Operating⣠the dryer â¤with⤠a broken or⣠badly worn rear slide âbearing lets âthe drum âŁsag âŁor rub on the bulkhead,â which accelerates wear on the âŁdrum, belt and idler, can damage the heater assemblyand creates a fire and reliability risk. Replace the bearingâ asâ soon⢠as âpossible.
How do âIâ know if â¤the WE3X87 isâ the correct replacement â¤part for my dryer model?
Always⣠confirm compatibility by âchecking your dryer’s model number and â¤the part number.The WE3X87 fits many GE and â¤Hotpoint⤠dryers but not all.â Use the modelâ number (usually on the dryer door frame or back panel) toâ look up replacement parts in theâ manufacturer’s parts list or on a reputable parts site. If in doubt, contact GE/Hotpoint customer support â˘orâ a qualified parts supplier.
Is âŁreplacing the WE3X87 something a homeowner can doand what⤠tools/skills are âneeded?
Yes, many homeowners with âbasic âmechanical âskills can replace the rear drum glide.â Typical⤠steps include unplugging power (and shutting off gas for gas dryers), removing the top or âfront access âpanels, taking the drum out âŁor tipping â˘it forward to access the rear bulkhead, removing â¤the old slideand installing the new⤠one. Common tools: screwdriver or nut driverâ set, socket setand possibly a putty⤠knife to release clips. Expect âabout 30-90 minutes depending on model and experience. If you’re not pleasant disassembling â¤the âdryer,hire a technician.
Do âI needâ grease or lubricantâ when installing the new rearâ drum slide bearing?
Most rear drum slides like the WE3X87 âare made from self-lubricating âŁmaterials (nylon or âa composite) andâ do notâ require added grease.
