This angular contact ball bearing carries radial and axial loads in one direction due to its contact angle design, with a single row of balls and a plastic cage (TVP). Bore diameter is 45.0 mm, outside diameter 100.0 mm, width 25.0 mm, and net mass 0.815 kg. The limiting speed reaches 9300 1/min, with a reference speed of 6500 1/min, reflecting the X-life design of the 7309-B-XL-TVP-UO. The plastic cage reduces friction and mass, supporting stable operation at the stated speed ratings. As a single row angular contact bearing, it should be mounted in pairs or combined with another bearing when axial loads act in both directions. No integrated seal is specified, so lubrication and contamination protection must be provided externally, matching the open design of this variant.
