Bearing rotating at high speed, especially the speed of approaching or exceeding the speed limit size table records, should pay attention to the following matters:
(1) the use of precision bearing;
(2) analysis of bearing internal clearance (bearing internal clearance considering temperature rise reduction);
(3) the analysis material of cage type (for high speed rotation, suitable for copper alloy or phenolic resin cutting holder. There is also suitable for synthetic resin forming high-speed rotating cage);
(4) analysis of lubrication (which is suitable for lubrication of high speed rotating, spray lubrication, oil mist lubrication and oil air lubrication, lubrication).
