Top Shelf Pom Flanged Sleeve Bearings, 4 Pack Zero Friction Self Lubricating Bushings, 6Mm Inner Diameter 7Mm Outer Diameter 8Mm Long Black Nylon Rotation Parts For No Fuss Diy Builds And Pro Gear Projects

4 pack pom flanged sleeve bearings drive smooth rotating shafts
✔️ 6mm inner x 7mm outer x 8mm long w 11mm flange for nylon bushes

These zero friction pom flanged oilless bushings act as maintenance free shaft sleeves to protect steel axles from scratching while handling steady rotational loads. You will typically snap them into hobby motors, 3d printer extruders, small conveyor pulleys, and home appliance gears.

✅ Pom self lubricating polymer cuts down on constant greasing chores
✅ 6mm 0.24 inch internal opening mates perfectly with steel axles
✅ 7mm 0.28 inch external wall fits snugly inside molded plastic housings
✅ 8mm 0.31 inch body height keeps your mechanical stack tight and flat
✅ 11mm 0.43 inch wide flange collar prevents sideways sliding under load

💡 How do oilless pom bushings manage continuous friction loads compared to traditional bronze sleeves?
This handy self lubricating assembly eliminates metal on metal scoring by using engineered polymer slides that carry axial weight without grease.
- Low coefficient of friction allows dry spindle rotation at high rpms
- Self wearing compound accommodates minor axle misalignment without binding
- Press fit geometry locks securely into cast aluminum or thermoplastic bores
