Oil-Embedded Sleeve Bearings
Startup friction causes these bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
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.

Self-Aligning Dry-Running Flanged Sleeve Bearings
Compensating for minor shaft misalignment and not requiring lubrication, these sleeve bearings swivel to self-align and are dry running. They don’t need a housing and you can install and replace them without any tools because they’re slip fit. Mount them in injection-molded panels, thin sheet metal, and hard non-ductile material. Made of acetal, they won’t warp or swell when exposed to water, so they’re good for washdown environments.
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 Double Flanged Sleeve Bearings
Form these bearings into a double flange and they’ll handle thrust loads from either direction. They have pre-cut fins on one end that you can flatten out against a surface to make a second flange. You can also use them as grommets to protect items passing through thin material like sheet metal. Made of a thermoplastic blend, they absorb little moisture and create very low friction in applications with lights loads and frequent starts and stops. Since they’re self-lubricating, they’ll resist wear for a long lifespan.

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.
Acetal bearings do not warp or swell when exposed to water, so they’re often used in washdown environments.
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.
Acetal sleeve bearings won’t warp or swell when exposed to water, making them good for use in washdown environments.
