What Are Roller Bearings? | Types and ApplicationsRoller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing frictionRoller Bearings | Bearings, Units & Housings | SKF SKF roller bearings are available in various cross sections and satisfy many operating conditions and performance requirements. Learn more on the SKF Roller & Cylindrical Bearings | AST BearingsRoller Bearings are a type of rolling-element bearing that uses cylinders (rollers) to maintain the separation between the moving parts of the bearing (as opposed to using balls as the rolling element). The purpose of a roller bearing is to reduce rotational friction and support radial and axial loads
