This bearing carries axial loads acting in both directions along the shaft axis, transmitting force through two rows of balls arranged back to back. It is built with a steel sheet metal cage (JP), reaches a height of 46.0 mm and a net mass of 1.116 kg. The limiting speed is rated at 4200.0 1/min, with a reference speed of 5200.0 1/min. As a double direction deep groove ball bearing, 52212 is suited for positions where axial forces alternate direction and radial load is negligible or absent, since this design does not support radial forces. The sheet metal cage keeps ball spacing stable at the stated speed range, and the double direction arrangement allows the shaft to be axially located in both directions with a single unit, without requiring a separate bearing for the opposite load direction.
