About Plain Bearings

High-Temperature Dry-Running Sleeve Bearings

Graphite provides a layer of dry lubrication that operates in high-temperature environments.

841 bronze bearings are porous and embedded with graphite for continuous lubrication.

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.

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.

High-Load Oil-Embedded Sleeve Bearings

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds. Startup friction causes them to release a thin layer of oil on the bearing’s surface. Color is silver because of the iron. These bearings are also magnetic due to the high iron content.

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.

Multipurpose Sleeve Bearings with Groove

A figure-8-shaped groove provides a flow path for lubricant, distributing it evenly along the bearing’s surface. Bearings are cast bronze, making them strong, wear resistant, and excellent at handling shock loads. 660 leaded bronze is sometimes called 932 bronze.

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.
