About Ball and Roller Bearings

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

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

Permanently Lubricated Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid 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.

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. 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.

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.

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.

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.

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.
