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.

Flanged Ultra-Thin Ball Bearings
Flanged and creating twice as many contact points as angular-contact ball bearings, these bearings ensure correct positioning within a tube or housing and resist radial loads.
Open bearings dissipate heat more efficiently than shielded bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

High-Load Dry-Running Sleeve Bearings
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.

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 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.

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.

Ultra-Low-Friction Dry-Running Flanged Sleeve Bearings
Use these bearings in applications with frequent starts and stops because they operate with very little friction.
Rulon J bearings stand up to higher temperatures than PTFE and thermoplastic-blend bearings.

Food Industry Dry-Running Flanged Sleeve Bearings
Made of FDA listed materials for use in food applications, these bearings also withstand caustic and washdown environments.
Acetal bearings are FDA compliant for direct contact with food. They’re commonly used on machines in food plants and manufacturing plants for packaging and healthcare equipment. These bearings are bright blue, so they’re easy to spot in your line in case of breakage.
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.

Needle-Roller Bearings
Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.
Open bearings dissipate heat more efficiently than sealed bearings.
