Ball Bearings

Open bearings dissipate heat more efficiently than shielded and sealed bearings.

Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Bearings with retaining ring have a removable retaining ring that holds the bearing inside a housing.

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Sealed bearings have even better resistance to dust and contaminants than open bearings.

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.

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.

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. As sleeve bearings, they handle loads parallel to the shaft.

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-Temperature Dry-Running Sleeve Bearings

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

954 aluminum-bronze bearings have high strength and excellent corrosion resistance, making them suitable for use in marine and mining applications.

Grooved bearings have a graphite-filled groove on the inside of the bearing that distributes lubricant evenly along the bearing’s surface.

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.
