This angular contact ball bearing carries radial and axial loads through a double row of balls guided against a particularly thick-walled outer ring, with axial guidance of the outer ring provided directly by the balls. The design is self-retaining, consisting of an outer ring, a ball and cage assembly, and an inner ring. Bore diameter is 12.0 mm, outside diameter 35.0 mm, height 15.9 mm, and net mass 0.08 kg. The cage, designation TVH, is made from glass fibre reinforced polyamide, and the bearing follows X-life design. Sealing shields (2Z) on both sides protect the raceway and ball set from contamination while retaining the internal grease fill. The thick-walled outer ring allows the bearing to run directly as a track roller surface without a separate outer sleeve, and the self-retaining assembly of inner ring, balls, and cage simplifies installation and removal as a unit. The polyamide cage keeps rolling friction low and supports the compact radial section given by the 12.0 mm bore against the 35.0 mm outside diameter.
