Axial Deep Groove Ball B. FAG 51230 -MP

The FAG 51230 -MP axial deep-groove ball bearing accommodates single-direction axial loads with a bore diameter of 150 mm and an outer diameter of 215 mm.

The 51230 -MP axial deep-groove ball bearing is designed as a single-direction rolling bearing. It guides shafts in an axial direction and absorbs the axial forces acting there. Manufactured from standard rolling-bearing steel (100Cr6), the bearing offers dimensional stability. The design complies with standard tolerance P0/PN or ABEC 1. Thanks to its solid brass cage, this design is suitable for demanding thermal conditions in the range from -30 to +150 degrees.

What are the requirements for using the 51230-MP axial bearing?

This axial bearing is designed to accommodate purely longitudinal forces where no radial loads act on the rolling elements. For combined loads, a separate radial bearing arrangement must be provided. As the design is not angle-adjustable and is supplied without a shim, the bearing mounting position requires careful alignment. The contact surfaces on the shaft and housing must be machined at right angles to the axis of rotation to prevent uneven force transmission to the balls.

What are the distinctive features of the solid brass cage (-MP)?

The designation -MP refers to a guided solid brass cage. Compared with sheet steel cages, brass is characterised by its run-on properties and mechanical strength. This reduces wear during rapid changes in speed or under continuous operating conditions. During assembly, the shaft disc fits tightly onto the 150 mm shaft, whilst the housing disc is fitted with some play into the 215 mm bore.
