Premium 8 Pack Pom Plastic Sleeve Bearings And Oilless Bushings Built Tough For Reliable Gear Upgrades Self Lubricating Design Keeps Engines Running Smooth No Fuss Assembly For 8 mm Id And 10 mm Shafts

Eight pack pom plastic bearings oilless bushings motor rebuild
✔️ Eight black pom sleeve bushings 8x10x8mm 0.31x0.39x0.31in set

This pack of eight POM plastic sleeve bearings acts as low friction oilless bushings designed for rotating or sliding shaft assemblies. They replace damaged hardware or shrink oversized mounting holes, keeping gears and pulleys aligned without seizing or creating excess drag. Workers install them in electric drills, 3D printers, conveyor rollers, and garage door openers where steady rotational movement matters.

✅ Inner diameter measures eight millimeters zero point three one inch for steel pins
✅ Outside diameter reaches ten millimeters zero point three nine inch for housing clearance
✅ Overall thickness sits at eight millimeters zero point three one inch for stack alignment
✅ Black thermoplastic compound handles radial loads without requiring additional liquid grease

💡 What makes self lubricating plastic sleeve bearings handy for DIY motor builds compared to metal versions?
The dry running design stops grit from welding inside tight shaft tolerances while saving you cleanup time. Check these performance facts:
- Polyoxymethylene core walls glide over hardened steel pins without grinding away the mating surface.
- Zero grease requirement stops filthy sludge from coating exposed wires and sensor mounts near the frame.
- Stable thermal rating handles fast spin speeds without popping past the outer housing clearance gap.
