When bearings are used for high speed, especially when the rotation speed approaches the limiting speed or exceeds it, the following should be considered :
(for further information on high speed, consult with JTEKT)
- Use of high precision bearings
- Study of proper internal clearance
(Reduction in internal clearance caused by temperature increase should be considered.) - Selection of proper cage type and materials
(For high speed, copper alloy or phenolic resin machined cages are suitable. Synthetic resin molded cages for high speed are also available.) - Selection of proper lubrication
(Suitable lubrication for high speed should be selected jet lubrication, oil mist lubrication and oil air lubrication, etc.)
