Rolling bearing for rotation movements

摘要

The bearing has rollers in two different groups. Rollers in one group are cylinder rollers (4) with cylindrical jacket, rollers in the other group are profile rollers (5) with a jacket having ring-shaped axial grooves. The groups form axial circumferential rows. Inner and outer bearing rings have a cylindrical race with cylinder faces for the cylinder rollers, and contact grooves (6) for the profile rollers.
