Our ball bearings are available to you off-the-shelf, in sizes ranging from 10 mm to 320 mm outside diameters. And with a virtually limitless variety of configurations of seals, shields, lubricants, internal clearances, and cage designs, there’s no reason to go anywhere else for your ball bearing needs.

Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.
