What does "lubried for life" mean? - Linear Motion Tips
18/3/2016· The simplest explanation of “lubried for life” is a linear bearing (or ball screw) that does not need re-lubriion over its normal service life. However, it’s important to understand how a manufacturer measures and defines life, and to compare those criteria to the appliion parameters where the bearing will be used.
What types of bearings are used in machine tool spindles?
The accuracy grade of the bearings used on the spindle of the machine tool should be ISOP5 or above, high temperature resistance and long life, so as to meet the needs of high-end customers for machine tool bearing products. For the contact angle of the
