Cylindrical Roller Bearings
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.
We offer premium cylindrical roller bearings under the NTN and Bower® brand names. Most NTN and all Bower® cylindrical roller bearings feature case-carburized components. Rings and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you’re looking for an American-made, case-carburized inch series cylindrical, or a metric series through-hardened variety, NTN has you covered with a proper fit to your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
