Heavy Duty 50Mm X 55Mm X 40Mm Oilless Sleeve Bearing With Sintered Bronze Backed Copper Core Worry Free Self Lubricating Plain Bushing For High Torque Motors And Shop Gearboxes Built Tough
✔️ Bore 50mm(1.97in), OD 55mm(2.17in), Len 40mm(1.57in)
This oilless sleeve bearing is a maintenance free plain bushing designed for high torque motors and shop gearboxes. The carbon steel cast copper core features a sintered porous bronze lining that stops wear before it starts. Mechanics drop these into textile machines, printing rigs, and hydraulic loaders when they want a handy fix that takes vibration away and keeps shafts spinning longer.
✅ Model 5040 runs steady with a dry friction range of 0.04 to 0.20✅ Sintered bronze backing slides smoothly against wet or dry shafts
✅ Sealed construction blocks corrosive oils from eating through metal
✅ Single pack shipping covers one complete replacement unit
💡 What makes a self lubricating plain bushing reliable for high torque motors?
These oilless sleeves are a handy choice for busy workshops because they cut maintenance headaches and extend component life. Mechanical crews rely on them for:
- Dense bronze backing layers spread weight evenly across rotating pins
- Carbon steel bases resist warping when facing heavy axial loads daily
- Slip fit geometry mounts fast without custom machining or extra tools
