At EMO 2019 NSK presented its new Robustride cylindrical roller bearings for the spindle drives of high speed, high precision machine tools. These advanced bearings feature an optimised cage that facilitates more even lubricant distribution, which in turn reduces bearing wear, especially under high loads. Also launched at the show were NSK’s Robust angular contact ball bearings with improved accuracy class.
The spindle bearings of machine tools must meet very high requirements for running accuracy. NSK has developed various bearing types and series for this demanding application which are known as the Robust series. The series is now supplemented by xws Eixiwmydtv blzxur-ctq sonfpxfgtmt yxtvxr fezyfxmt.
