This double row angular contact ball bearing carries axial loads in both directions together with radial loads, thanks to its two rows of balls arranged to contact the raceways at an angle. The design includes a filling slot, which increases the number of balls per row and raises load capacity compared with a standard configuration. Bore diameter is 85.0 mm, outside diameter 150.0 mm, width 49.2 mm, and net mass is 3.316 kg. Limiting speed is rated at 4650 1/min, with a reference speed of 4700 1/min. The cage is a pressed steel sheet metal cage, symbol J, guided by the balls and suited to the speed range stated above. The filling slot design allows the bearing to combine radial stiffness with bidirectional axial guidance in a single unit, reducing the need for a paired arrangement. As supplied open, without integrated sealing, it requires external sealing and a separate lubrication supply appropriate to the mounting position and speed conditions.
