LR5204-X-2Z-TVH-XL is a double row angular contact ball bearing built as a yoke type track roller with a particularly thick-walled outer ring, a ball and cage assembly and a separate inner ring. Axial guidance of the outer ring is provided directly by the balls, giving the unit self-retaining properties. Bore diameter is 20.0 mm, outside diameter 52.0 mm, height 20.6 mm, and net mass 0.23 kg. The cage, designated TVH, is made from glass fibre reinforced polyamide, and the bearing is produced in X-life design. Both sides carry 2Z sealing shields, protecting the ball and cage assembly against contamination while retaining lubricant inside the bearing. A lubrication hole in the inner ring is available on request, allowing relubrication without dismounting the roller. The thick-walled outer ring combined with direct ball guidance allows this angular contact ball bearing to run in rolling contact against a track surface, carrying combined radial and axial loads while maintaining self-retention of the outer ring.
