This single row angular contact ball bearing carries contact angle design that supports combined radial and axial loads in one direction. Bore diameter is 25.0 mm, outside diameter 47.0 mm, width 12.0 mm, and net mass 0.075 kg. The X-life execution refers to optimised internal geometry for extended operating performance. Cage is TVP, a solid plastic cage. Limiting speed for this bearing reaches 8100.0 1/min. Sealing is provided on both sides (2RS), preventing contamination ingress and retaining lubricant inside the bearing. Due to the single-direction contact angle, this bearing should be mounted in pairs or in combination with a second bearing capable of taking axial load from the opposite direction, depending on the shaft arrangement. The two-side sealing eliminates the need for external protection and supports maintenance-free operation once grease-filled, without relubrication access. The plastic cage reduces friction and mass compared to metal cage designs, supporting the stated limiting speed value.
