This angular contact ball bearing carries a particularly thick-walled outer ring together with a ball and cage assembly and an inner ring, providing axial guidance of the outer ring through the balls themselves. Bore diameter is 30.0 mm, outside diameter 80.0 mm, height 30.2 mm, and net mass 0.67 kg. The double row design is self-retaining, and the cage (TVH) is made from glass fibre reinforced polyamide, following the X-life design principle. Sealing shields are fitted on both sides (2Z), keeping contaminants out of the ball and cage assembly and retaining lubricant within the bearing. The thick-walled outer ring gives the unit high load-carrying capacity for its size, while the ball-guided axial support of the outer ring allows it to run as a track roller under continuous rolling contact loads.
