This double row angular contact ball bearing carries radial and axial loads in both directions within a single unit, using an X-life optimized internal design for increased load rating within standard boundary dimensions. Bore diameter is 50.0 mm, outside diameter 110.0 mm, width 44.4 mm, net mass 1.78 kg, and the limiting speed reaches 4900 1/min. The bearing is fitted with a TVH cage made of glass-fiber reinforced plastic and sealed on both sides (2HRS), keeping grease inside and contaminants out. The two-row arrangement and integrated sealing make this bearing suitable for applications where combined loads act on the shaft and where relubrication access is limited. The polymer cage reduces friction and mass compared to a metal cage, supporting stable operation up to the stated limiting speed. Factory grease fill together with the 2HRS seals allows operation without additional external sealing, provided that mounting tolerances match the specified bore and outside diameter.
