This double row angular contact ball bearing carries loads from both directions along the axis and locates the shaft in both directions with a single unit. Bore diameter is 50.0 mm, outside diameter 90.0 mm, width 30.2 mm, and net mass 0.664 kg. The X-life design provides increased load rating within the same envelope dimensions. The limiting speed is 7800 1/min and the reference speed 7600 1/min, with a TVH cage made of glass-fibre reinforced polyamide. The polyamide TVH cage reduces friction and mass, supporting stable operation up to the stated speed limits, and its design accommodates thermal expansion at higher running temperatures. The C3 internal clearance compensates for interference fits and temperature rise during operation, keeping the bearing free of excessive preload. The double row arrangement makes it suitable for applications requiring stiff axial guidance in both directions without a second bearing, combined with the load capacity typical of X-life bearings.
