This angular contact ball bearing carries radial and axial loads in one direction through its single-row design with a defined contact angle. Bore diameter is 12.0 mm, outside diameter 37.0 mm, width 12.0 mm, and net mass 0.06 kg. The X-life design provides raceway geometry optimized versus standard execution, and the TVP cage is a solid plastic cage guiding the ball set. Limiting speed reaches 28000 1/min, with a reference speed of 16300 1/min. The P5 accuracy class suits applications requiring tighter running accuracy and reduced radial and axial runout compared to standard tolerance bearings. Since this is a single-row angular contact ball bearing, it should be mounted as a matched pair or against a counterpart to take up axial load from both directions, with the contact angle set by the design determining the axial-to-radial load ratio it can support. The plastic TVP cage keeps mass low and supports the stated speed ratings, and open design without an integrated seal or shield means separate sealing and lubrication provisions must be arranged by the user.
