This single row angular contact ball bearing carries radial and axial loads in one direction due to its contact angle design, transmitting combined loads through the raceway geometry. Bore diameter is 70.0 mm, outside diameter 125.0 mm, width 24.0 mm, with a net mass of 1.207 kg. The bearing is fitted with a solid brass cage (MP) and belongs to the X-life series, offering limiting speed of 9400 1/min and reference speed of 5500 1/min. The solid brass cage provides stable ball guidance and mechanical strength at the stated speed range, supporting reliable operation under combined loading. As a single row design, this bearing is typically mounted in pairs or in combination with another bearing to accommodate axial loads acting in both directions. The X-life manufacturing standard indicates tighter internal geometry tolerances, contributing to load distribution and running accuracy within the given speed limits.
