This angular contact ball bearing carries radial and axial loads through a double row of balls arranged between a particularly thick-walled outer ring and an inner ring, with axial guidance of the outer ring provided directly by the balls. Bore diameter is 15.0 mm, outside diameter 47.0 mm, height 19.0 mm, and net mass 0.17 kg. The cage, coded TVH, is made from glass fibre reinforced polyamide, giving a low-friction, self-retaining ball and cage assembly of X-life design. Sealing is provided on both sides by lip seals with optimised geometry, coded 2HRS, keeping contaminants out while maintaining low running friction. The self-retaining construction and thick-walled outer ring allow the roller to be handled and mounted as a complete unit without losing its ball complement, and a lubrication hole in the inner ring can be supplied on request for relubrication during service.
