High-Load Dry-Running Sleeve Bearings
Plastic Bearings
with Steel Shell
A metal shell adds strength.
Bronze-backed PTFE bearings with steel shell combine high-load and high-speed capabilities. They resist swelling when exposed to moisture and are electrically conductive.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Dry-Running Mounted Sleeve Bearings
Made from slippery materials, these bearings reduce friction without the oily mess. They are self-aligning to compensate for shaft misalignment.
Bronze bearings have embedded particles of slippery PTFE to reduce friction during startup.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Dry-Running Mounted Sleeve Bearings with Two-Bolt Flange
Embedded lubricant particles increase the load capacity of these bearings while also making them slippery. Bearings are self-aligning to compensate for shaft misalignment.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.
