Design features of machine tool precision spindle bearings

In recent years, the performance of the machine tool spindle further to the high speed bearing , high precision, high stiffness and the direction of development. To meet these requirements at the same time,it also must be conducive to environmental protection and pay attention to global warming and other environmental issues.

  Special design, Mr. Yu Jiong said, bearing design NSK (LYHY precision spindle bearings peer)as the core to tribology, rely on four core technology of Tribology (evaluation of analytical technology, technology, lubrication technology and material technology).

  For the design of machine tool spindle bearing is even more so, first of all, NSK to use its technology to develop a bearing material of long life, high performance.

  Secondly, the design of the rolling body, we developed in high speed and ultra high speed environment, various aspects of ceramic material with excellent performance, effectively realizes the rotation for ultra high speed, ultra high precision metal rolling body cannot reach, won the overwhelming majority of users.

  In addition, NSK (LYHY precision spindle bearing peer)development and design of special shape rolling body guide resin retainer with grease, running in a short time, temperature stability, low friction, low noise, especially can play a better effect in grease lubrication conditions, while for the roller and precision cylindrical Full complement cylindrical roller bearings ,it is ultra high performance PPS and PEEK resin material, has the advantages of high speed and heat resistance is more superior.
