This single row angular contact ball bearing takes up combined radial and axial loads in one direction, with the contact angle setting the load line through the balls. Bore diameter is 10.0 mm, outside diameter 30.0 mm, and width 9.0 mm, giving the envelope dimensions for seat and housing design. Mass netto is 0.032 kg, a reference value for handling only. The limiting speed is rated at 16100 1/min. The bearing uses a TVP cage, a glass-fibre reinforced plastic cage design from the X-life line, contributing to the stated speed rating. Both sides are fitted with seals (2RS), retaining grease fill and keeping out contamination without added axial guidance. As a single row angular contact design, it should be mounted as part of a pair or against a counter-bearing when axial loads act in both directions. The plastic TVP cage keeps ball spacing with low friction, supporting running at the stated limiting speed under grease lubrication.
