High-Load Ball Bearings
With a wider profile than standard ball bearings, these rugged bearings are good for handling heavy loads at low speeds.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.
Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Stainless Steel Ball Bearings
Bearings are 440C stainless steel for good corrosion resistance.
Open bearings dissipate heat more efficiently than shielded and sealed 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.

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.

Low-Profile Mounted Ball Bearings with Two-Bolt Flange
Designed with a thin, compact housing, these bearings are good for space-constrained applications. Seals block out dust and contaminants.
Steel bearings are stronger than stainless steel bearings, but not as corrosion resistant.Bearings with a set screw secure to shafts without using a collar. They let shafts rotate in both directions, so they’re good for applications where you need to reverse. However, the set screw will leave some marring on the shaft.
