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).
