YJ6912 matched bearings preload measuring instrument

• 
  The preload of matched bearing is a key parameter. Its accuracy directly affects the performance of matched bearings as well as host. When doing the original installation, bearing will have a certain pre-deformation. So the main role of preload is to make the bearings skip the initial large deformation stage. It significantly increases the support rigidity. In addition, the matched bearings are used in precision bearing system which needs higher accuracy.

  The instrument for preload measurement can measure the preload of matched bearings quantitatively and accurately, ensuring the rigidity, precision and speed of bearings in an optimized status.
