31.8mm OD Bearings | McMaster-Carr

Reduce upkeep with sleeve bearings that lubricate themselves. Made from porous, oil-saturated bronze, they release a thin film of lubrication upon startup to keep shafts spinning. With no moving parts, sleeve bearings withstand dusty, dirty environments better than ball or roller bearings. However, with more friction generated, they're less effective at high speeds. They mount securely in thin panels.

Steel Housing—Best for dry environments as moisture will cause them to rust.

Clinch Panel Mount—Secure these self-clinching bearings into sheet metal panels for a permanent hold. Install them using an air-powered or hydraulic press—no need for precision-bored holes or machined mounts. They're not for use in plastic panels.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.
