HZK Thrust ball bearing components: A thrust ball bearing consists of a seat washer, a shaft washer, and a steel ball cage assembly. The shaft washer mates with the shaft, while the seat washer mates with the housing. Thrust ball bearings are classified according to load conditions as single-direction and double-direction. Cages are categorized as steel or copper.
HZK Double direction thrust ball bearings type 52000 can withstand axial thrust loads in two directions, and can limit the movement of the shaft and housing in one direction. These bearings have a separable design for easy installation, removal and bearing inspection.
HZK Type 53000 bearings are single direction thrust bearings with spherical housing locating washers to accommodate axial loads in one direction. They must not bear any radial loads. Many components are interchangeable. The shaft washers have ground holes for an interference fit. This type not only has a separable design for easy installation/removal and maintenance inspection, but also interchanges
HZK 53000 U-Bearings are bearings with self-aligning seat washers that can be used with self-aligning seat washers to compensate for angular misalignment between the support surface in the housing and the shaft. Depending on the bearing series, spherical seat washers have the basic designation U 2, U 3 or U 4, plus two digits indicating the size (eg spherical seat washer U 320 for bearing 53320).
