This single row angular contact ball bearing carries a 50.0 mm bore, 110.0 mm outside diameter and 27.0 mm width, with a net mass of 1.19 kg. It belongs to the X-life design line and is fitted with a solid brass cage (MP). The limiting speed is 10900 1/min, with a reference speed of 6100 1/min. The angular contact design allows the bearing to carry combined radial and axial loads acting in one direction, with load capacity increasing as the contact angle transmits axial forces through the ball set. The solid brass cage gives the rolling elements stable guidance at the stated speed values and supports reliable operation under the combined loading typical of this bearing arrangement. As supplied, the bearing has no seal or shield, so lubricant selection and external sealing must be arranged by the user according to the operating conditions.
