The precision of rolling elements is the most important factor that affects the bearing rotational accuracy. The general application of each precision grade of bearing rollers showing as in the below table:
Precision grade of bearing rollers
Precision grade of the Bearing
For some low-noise bearings, also required to assembled with bearing rollers with precision grade 0 or I.
Because it is not easy to purchase high precision bearing rollers in the market, and in order to meet the needs of high precision bearings of our own, we set up our own bearing rollers production line.
Through technical exploration and innovation, the processing technology of grade 0 / 1 cylindrical rollers has been fully grasped, and the surface of rollers can be completely grinding into logarithmic curve. This shape is the most ideal for the load distribution and self-lubricating of cylindrical rollers.
TEDIN have precision roundness measuring meter, profile measuring meter, high precision altimeter and harness measuring meter, for tests on cylindrical rollers’ roundness, profile, and roughness, height and hardness etc.
