About Plain Bearings

Use these bearings in applications with frequent starts and stops because they operate with very little friction.

Rulon J bearings create the least amount of friction of any bearing that we offer. They handle heavier loads than PTFE 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.

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.

High-Load Food Industry Oil-Embedded Sleeve Bearings

Embedded with oil that is safe for incidental contact with food, these bearings are suitable for use in high-load applications such as bottling and filling lines in food processing plants. They are also known as Super Oilite® bearings. Startup friction releases the embedded oil onto their surface in a thin layer. Bearings are made of 863 iron-copper, which makes these bearings strong and resistant to shock loads.

Bearings with NSF H1 registered lubrication comply with NSF standards for incidental contact with food.

High-Load Ultra-Low-Friction Oil-Embedded Sleeve Bearings

Use these bearings for frequent starts and stops in high-load applications. Startup friction causes these bearings to release a thin layer of oil that contains PTFE to lubricate the bearing’s surface. All have more iron content than standard oil-embedded bearings to handle heavier loads and higher shock loads, but operate at lower speeds.

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.

Light Duty Dry-Running Flanged Sleeve Bearings

Use where high loads and speeds are not required.

Thermoplastic-blend bearings have low moisture absorption and create very low friction in applications with light loads, and frequent starts and stops.

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.
