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

Food Industry Permanently Lubricated Stainless Steel Ball Bearings
Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and ring that eliminates 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 Ball Bearings
The flange ensures proper positioning inside a tube or housing.
440C stainless steel bearings are more corrosion resistant than steel bearings.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.

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.
