This angular contact ball bearing carries combined radial and axial loads acting in one direction, with a single row of balls arranged at a contact angle. It has a bore of 55.0 mm, outside diameter of 100.0 mm, and width of 21.0 mm, with a net mass of 0.625 kg. The design belongs to the X-life series and uses a JP cage made of steel sheet metal. Limiting speed is 9200 1/min, and reference speed is 6800 1/min. The steel sheet metal JP cage guides the balls with reduced friction and supports stable operation at the stated speed values. Since the bearing takes load in a single direction only, it is typically mounted in pairs to handle axial forces from both sides. No integrated sealing is specified, so lubricant supply and contamination protection must be arranged externally, and mounting should maintain the correct axial preload for the contact angle to work as intended.
