Bearing rotating at high speed, especially speed is close to or exceeds the size limit table records speed, the main should pay attention to the following matters: bearin gs high speed
(1) The use of precision bearings
(2) analysis of bearing internal clearance (taking into account the temperature rise of the bearing internal clearance reduction)
(3) analysis of the cage material type (for high-speed rotation, suitable for cutting copper alloy or phenolic resin cage.
Also applies to the high-speed rotation of the synthetic resin molded holder)
(4) the analysis of lubrication manner (using suitable for high-speed rotation cycle lubrication spray lubrication, oil mist lubrication and oil lubrication lubrication. single ball bearing
