This angular contact ball bearing is a double row, self-retaining design with a particularly thick-walled outer ring, providing axial guidance of the outer ring through the balls themselves. Bore diameter is 17.0 mm, outside diameter 47.0 mm, height 17.5 mm, and net mass is 0.17 kg. The cage, designated TVH, is made from glass fibre reinforced polyamide, contributing to low friction operation. Sealing is designated 2HRS, consisting of a lip seal on both sides with optimised geometry. The double row ball arrangement combined with the thick-walled outer ring allows this bearing to handle combined radial and axial loads while maintaining guidance without a separate track. The two-sided lip seal protects the raceway and ball set from contamination while keeping friction low, and the polyamide cage supports smooth rolling motion under continuous operation. The X-life design indicates optimised internal geometry for consistent running accuracy over the bearing's working life.
