Description
This four-point contact bearing carries radial loads together with axial loads acting in either direction, using a single row of balls contacting each raceway at four points. Bore diameter is 50.0 mm, outside diameter 110.0 mm, width 27.0 mm, and net mass is 1.317 kg. The cage is a solid brass design, designation MPA, and the internal clearance corresponds to C3. Limiting speed is 12500 1/min, reference speed 5400 1/min. The separable design of the four-point contact bearing allows the two ring halves to be mounted independently, simplifying installation where axial positioning of a shaft in both directions is required from a single bearing position. The solid brass cage supports stable ball guidance at the stated speed values, while the C3 clearance compensates for temperature rise during operation. As supplied without integrated sealing, lubrication and protection against contamination must be provided externally, and relubrication intervals should be set according to the reference speed value given.
