Built Like A Tank 3 Pack Bronze Sleeve Bearings Self Lubricating Bushing Set Measuring 14mm Inner By 20mm Outer Diameter And 25mm Length Provides Heavy Load Support For Reliable Industrial Machine Repair And Motor Tune Ups

3 Pack Bronze Sleeve Bushings For Motor Shaft Rotation
✔️ Heavy duty sintered bronze self lube bushings 14mm inner 20mm outer

This handy set of oil impregnated bronze sleeve bearings delivers smooth sliding motion for rotating shafts across electric motors, printing press rollers, and general industrial machinery. The dry running design keeps friction low while handling steady heavy loads without requiring constant manual greasing.

✅ Inner diameter measures 14mm or 0.55inch for snug shaft fit
✅ Outside diameter spans 20mm or 0.79inch for solid housing stability
✅ Overall length sits at 25mm or 0.98inch for balanced mounting depth
✅ Operating temperature ranges from minus 80C to plus 160C for extreme conditions
✅ Friction coefficient drops between 0.12 and 0.18 for smooth rotation

💡 How do sealed ball bearing units prevent shaft wear in high torque motor assemblies?
Sintered powder metal construction combined with factory filled lubricant creates durable sliding surfaces that withstand continuous rotational wear.
- The oil impregnated bronze matrix self adjusts to heat and pressure during motor rebuilds
- Low sliding friction characteristics keep operating temperatures stable while extending maintenance intervals
- Handy replacement fits standard housing bores for quick industrial machine repairs and motor tune ups
