MRC® SPLIT INNER RING BALL BEARING SETS DESIGNED TO ACCOMMODATE THRUST IN EITHER DIRECTION

MRC® 97000 Series angular contact ball bearing sets feature a split inner ring design allowing for an optimum ball complement and the capability to accommodate thrust in either direction. With two bearings acting in tandem to share primary thrust load, these sets can handle the especially heavy loads encountered in vertical pump applications. This two-bearing arrangement can match the performance of traditional three-bearing sets, while requiring fewer components and minimal space in an assembly. The sets consist of bearings with 29º contact angles (97000U2 Series) or 40º contact angles (97000U2P Series). Both incorporate an MRC 9000 split inner ring bearing matched in tandem with a single MRC 7000 or 7000P bearing with the same contact angle. Thrust capacity is shared by two bearings in one direction and by one bearing in the reverse direction. These ball bearing sets are available in metric bore sizes ranging from 65mm to 150mm (2.5 in. to 5.9 in.); engineered to ABEC-1 precision tolerances; and feature extremely durable machined bronze cages.
