LR5201-X-2Z-TVH-XL is a double row angular contact ball bearing designed as a yoke type track roller, built with a particularly thick-walled outer ring, a ball and cage assembly, and an inner ring. The outer ring is axially guided by the balls, forming a self-retaining unit. Bore diameter is 12.0 mm, outside diameter 35.0 mm, height 15.9 mm, net mass 0.08 kg. The cage, designated TVH, is made from glass fibre reinforced polyamide, following the X-life design. Sealing shields on both sides (2Z) protect the raceway and ball set from contamination on both faces of the roller. A lubrication hole in the inner ring can be supplied on request, allowing relubrication without dismounting the unit. The thick-walled outer ring together with the self-retaining ball and cage assembly lets the roller run directly on a track surface, with the guided outer ring taking up both radial and axial loads.
