Oil-Embedded Sleeve Bearings
Startup friction causes these porous bronze 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.

Ultra-Low-Friction Oil-Embedded Sleeve Bearings
For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing 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.

High-Load Ultra-Low-Friction Oil-Embedded Sleeve Bearings
With extra iron and filled with oil containing slippery PTFE, these bearings support heavy loads that frequently start and stop along shafts. Startup friction causes a thin layer of oil to release onto the surface. Their high iron content also means they resist failing if their load suddenly and drastically increases, but they won’t run as fast as standard 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.

High-Speed Self-Aligning Dry-Running Flanged Sleeve Bearings
Made of acetal with a PTFE filler, these bearings handle velocities up to twice as high as standard acetal bearings. They’re self-lubricating, so they’ll take on less wear for an increased lifespan. Acetal won’t warp or swell from exposure to water, so these bearings are good for use in washdown environments. These bearings swivel to compensate for a small amount of shaft misalignment. Designed for press-fit installation by hand—no tools required—they don’t need to be fitted into a housing. Mount them into injection-molded panels and mounts, thin sheet metal, or hard non-ductile materials.
