This angular contact ball bearing carries axial guidance of the outer ring through the ball complement, a design built as a double row self-retaining unit with a particularly thick-walled outer ring, a ball and cage assembly, and an inner ring with 30.0 mm bore diameter. Outside diameter is 80.0 mm, height 30.2 mm, and net mass 0.67 kg. The cage, coded TVH, is made from glass fibre reinforced polyamide, and both sides are closed with 2Z sealing shields. The thick-walled outer ring gives the raceway surface high resistance to contact loads transmitted through rolling motion, while the self-retaining double row arrangement keeps ball and cage assembly, inner ring and outer ring together as one unit during handling and mounting. The 2Z sealing shields on both sides keep the internal grease fill protected from contamination without requiring external sealing arrangements. The polyamide TVH cage reduces running friction and mass compared with metal cages, which suits the bearing to applications where the outer ring itself acts as the rolling track. A lubrication hole in the inner ring can be requested for relubrication with grease during service.
