Compared to other processing facilities that specialize in the production of bearings, ZZ Bearing facilities feature high efficiency, low error and superior precision.

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.

• Rockwell Hardness Tester

  • 

  • 

  ZZ Bearing 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.

• Roundness Measuring Machine

  • 

  • 

  Bearing vibration velocity is determined by its roundness. The Roundness measuring instrument that ZZ Bearing uses can detect even subtle errors through improved measuring methods including a rotor method, three-point method, projection method and coordinate method.
