0.2508" ID 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, they withstand dusty, dirty environments better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing bolts down to support shafts as they turn.

Aluminum Housing—One-third the weight of cast iron but not as strong. Aluminum also resists corrosion.

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.

Oil-Embedded Panel-Mount Sleeve Bearings

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.

Oil-Embedded Mounted Sleeve Bearings with Two-Bolt Flange

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. The sturdy housing supports the shaft and secures with a two-bolt flange, the most common type of flanged bearing.

Aluminum Housing—One-third the weight of cast iron but not as strong. Aluminum also resists corrosion.
