This angular contact ball bearing carries axial guidance of the outer ring through the balls themselves, with a particularly thick-walled outer ring, ball and cage assembly and an inner ring forming a self-retaining double row unit. Bore diameter is 35.0 mm, outside diameter 90.0 mm, height 34.9 mm, and net mass 0.97 kg. The cage is made from glass fibre reinforced polyamide (TVH), and the X-life design applies to the internal geometry and load-carrying components. Sealing is provided on both sides by lip seals with optimised geometry (2HRS), giving low friction while keeping contaminants out of the raceway and ball set. The double row, self-retaining construction allows the unit to be handled as one piece during mounting, and the thick-walled outer ring gives it the rigidity needed for direct rolling contact against a track or rail surface without an additional housing.
