Carries axial loads acting from both directions along the shaft axis, transmitting them through two rows of balls arranged for double-direction operation. The bearing 52211 has a height of 45.0 mm and a net mass of 1.033 kg, with a limiting speed of 4350.0 1/min and a reference speed of 5600.0 1/min. The ball complement is guided by a pressed steel sheet metal cage, designation JP. The double-direction arrangement allows the bearing to take up axial forces from either side, so it is suited to shaft arrangements where axial load direction reverses or where the shaft must be positioned axially in both directions. As an axial deep groove ball bearing, it does not accommodate radial loads and requires a separate radial bearing to support the shaft. The steel sheet metal cage keeps mass low while maintaining ball spacing at the stated speed limits.
