About Plain Bearings

Bronze-Backed PTFE
Plastic Bearings
with Steel Shell

A metal shell adds strength.

Bronze-backed PTFE bearings with steel shell combine high-load and high-speed capabilities. They resist swelling when exposed to moisture and are electrically conductive.

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 Dry-Running Sleeve Bearings

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

Rulon J bearings handle higher operating temperatures than PTFE or thermoplastic-blend bearings.

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

Food Industry Dry-Running Sleeve Bearings

Made of FDA-listed materials or FDA compliant, these bearings are for use in food applications. They also withstand caustic and washdown environments.

Acetal bearings are FDA compliant for direct contact with food. They’re also bright blue, making them easy to spot if they fall into your line.

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 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.

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.

Oil-Embedded Flanged Sleeve Bearings

Startup friction causes these bearings to release a thin layer of oil on the bearing’s surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft. They’re 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 Flanged 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 these bearings to release a thin layer of oil onto their surface. Color is silver because of the iron.

863 iron-copper bearings are also known as Super 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.

Food Industry Oil-Embedded Flanged Sleeve Bearings

The oil in these bearings is suitable for incidental contact with food. Startup friction produces a thin layer of oil on the bearing’s surface. All are FDA Compliant, so they're safe for use in food applications.

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 Flanged Sleeve Bearings

Support heavy loads that are often found in bottling and filling lines in food plants—these bearings contain extra iron and FDA-compliant oil. The oil is safe to touch food, though it shouldn’t regularly come in contact. Startup friction causes these bearings to release a thin layer of oil onto their surface. They’re flanged, so they handle loads both parallel and perpendicular to the shaft.

841 bearing bronze bearings run at higher speeds than 863 iron-copper bearings. They’re also known as Oilite® bearings.
