Compared to other processing facilities that specialize in the production of bearings, ZZ Group facilities feature high efficiency, low error and superior precision.Exhibition of processing facilities
During the installation of bearings, our assembly worker will not only check its anti-chucking ability, but also clean potential burrs, rusty spot on the surface, ensuring ideal bearing products for our customers.
ZZ Group measures bearing hardness with a Rockwell Hardness Tester. The hardness index is closely correlated with abrasion resistance and elastic limit, hence we recommend choosing high-hardness bearing which can support higher loads.
Bearing vibration velocity is determined by its roundness. The Roundness measuring instrument that ZZ Group uses can detect even subtle errors through improved measuring methods including a rotor method, three-point method, projection method and coordinate method.
