Description
This four-point contact bearing carries combined radial and axial loads in both directions on a single row of balls, using a divided inner ring construction. Bore diameter is 90.0 mm, outside diameter 190.0 mm, width 43.0 mm, and net mass is 6.18 kg. The bearing features holding grooves and runs on a solid brass cage (MPA). Limiting speed is rated at 6300.0 1/min, with a reference speed of 3350.0 1/min. The design allows this bearing to support axial loads from either direction while occupying the space of a single-row bearing, making it suitable where combined loading must be handled without stacking multiple bearings. The solid brass cage (MPA) provides stable ball guidance at the given speed ratings, while the holding grooves assist in mounting and retention of the bearing halves during assembly.
