Bearing Super Technology:Ultra-High Speed|Products & …

To lubrie bearings to achieve ultra-high-speed revolution, we adopted air-oil lubriion, in which air is used with a small amount of oil. Using the minimum necessary oil along with air and accurately supplying it to the boundary between the ball and the race provides sufficient lubriion while preventing the temperature from rising.

High Speed Bearings for Machine Tool Spindles - ScienceDirect

A major car manufacturer reports that the greatest part of machines down time is due to spindle bearings failure, despite the fact that their loads are generally very low. It is Shown in this paper that the main reason for these early failures is thermal instability of the bearings/spindle/spindle housing assely, that leads to uncontrolled hertzian stresses and hence to bearing destruction.

Selecting a suitable grease | SKF | SKF

Lubriing super-precision bearings with suitable quantities of good quality grease permits relatively high speed operation without an excessive rise in temperature. The use of grease also means that the design of a bearing arrangement can be relatively simple because grease is more easily retained in a bearing arrangement than oil, particularly where shafts are inclined or …
