This angular contact ball bearing carries axial guidance of the outer ring through the ball set, with a particularly thick-walled outer ring, ball and cage assembly and an inner ring forming a double row, self-retaining unit. Bore diameter is 35.0 mm, outside diameter 80.0 mm, height 27.0 mm, net mass 0.66 kg. The cage is made from glass fibre reinforced polyamide (TVH), and sealing is provided on both sides by lip seals with optimised geometry (2HRS). The thick-walled outer ring allows the bearing to run directly on a track as a yoke type roller, while the ball-guided axial support keeps friction low during rotation. The double-sided lip seals with optimised geometry reduce running friction while keeping contamination out, supporting the X-life design intended for stable, low-friction operation over the bearing's working life.
