Product description of FAG Bearing 51240-MP

FAG Bearing 51240-MP Axial Deep Groove Ball Bearings are single direction or double direction ready-to-fit units that can support high axial forces and are not self-retaining. Owing to their construction, the bearing parts (shaft locating washer, housing locating washer, ball and cage assembly, support washer) can be mounted separately from each other.

Single direction bearings comprise a shaft locating washer and a housing locating washer between which a ball and cage assembly is arranged. They can support axial forces in one direction and support the shaft on one side.

Double direction bearings comprise a shaft locating washer, two housing locating washers and two ball and cage assemblies. This design can support axial forces in both directions and can therefore guide the shaft on both sides.

FAG Bearing 51240-MP, In addition to the series with flat housing locating washers, axial bearings with curved locating surfaces are also available for the compensation of static angular misalignment. These designs are normally used in conjunction with support washers and tolerate static assignments of the shaft relative to the housing. They are not suitable, however, for wobble type motions of the shaft, since the friction on the curved locating surfaces is too high.

FAG Bearing 51240-MP, Axial deep groove ball bearings:

  • are standardized, ready-to-fit units with high axial load carrying capacity.
    • are suitable exclusively for the support of predominantly axial loads.
      • are particularly suitable where the bearing position is subjected to high axial loads from one or both sides, but the requirements for axial load carrying capacity are not so high that axial cylindrical roller bearings with even higher load carrying capacity must be used permit higher speeds than roller or needle roller and cage assemblies compensate, in conjunction with a spherical housing locating washer, static misalignment s between the shaft and housing.

      Non-self-retaining, easy-to-fit bearing units

      Axial deep groove ball bearings are part of the group of axial ball bearings. The bearings are of a multi-piece construction and, due to their design, are not self-retaining. As a result, it is possible to mount the bearing parts (shaft locating washer, housing locating washer, ball and cage assembly, support washer) separately from each other. In order to guide the balls, the shaft and housing locating washer have raceway grooves (formed rolling element raceways) with a defined osculation, in which the rolling elements circulate. The ball set is retained by a sheet steel cage or a solid brass cage. When using these bearings, the designer does not need to produce the bearing parts for his bearing arrangement and match these to each other himself, but can instead use a standardized, ready-to-fit unit.

      Ready-to-fit bearing unit for compact axial designs

      These axial deep groove ball bearings comprise a shaft locating washer, a housing locating washer and a ball and cage assembly. In order to ensure cent-ring of the washers with a precise fit, the bore of the shaft locating washer (d) is ground. In contrast, the bore of the housing locating washer (D1) is more generously dimension-ed and is turned. The housing locating washer can be flat or spherical and can be configured with or without a support washer. The support washers U2 and U3 must be ordered in addition to the bearing.Load carrying capacity of single direction bearings.
