This angular contact ball bearing carries radial and axial loads through a double row of balls arranged in a self-retaining ball and cage assembly, with a particularly thick-walled outer ring whose axial guidance is provided directly by the balls. Bore diameter is 30.0 mm, outside diameter 80.0 mm, height 30.2 mm, and net mass 0.67 kg. The cage (TVH) is made from glass fibre reinforced polyamide, contributing to low friction operation. Sealing is provided on both sides by lip seals with optimised geometry (2HRS), protecting the internal ball and cage assembly from contamination while keeping friction low. The X-life design and thick-walled outer ring support stable running under radial and axial loading in yoke type track roller applications, and a lubrication hole in the inner ring is available on request for relubrication during service.
