Bearing high speed rotation precautions

Core Tip: When the bearing rotates at high speed, especially when the speed is close to or exceeds the limit speed recorded in the dimension table, the following should be noted: (1) using precision bearings; (2) analyzing the inside of the bearing
When the bearing rotates at high speed, especially when the speed is close to or exceeds the limit speed stated in the dimension table, the following should be noted:

     (1) use precision bearings;

     (2) Analyze the internal clearance of the bearing (considering the reduction of the internal clearance of the bearing caused by the temperature rise);

     (3) Analyze the type of material of the cage (for high-speed rotation, it is suitable to use a copper alloy or phenolic resin cutting cage. There is also a synthetic resin molding cage suitable for high-speed rotation);

     (4) Analyze the lubrication method (using lubrication methods such as circulating lubrication, jet lubrication, oil mist lubrication and oil and gas lubrication for high-speed rotation)
