Precautions for bearing when rotating at high speed

when the bearing rotates at the rumble of high-speed automatic conveyor belt, especially when the speed is close to or exceeds the limit speed recorded in the dimension table, the following matters should be paid attention to:

(1) use precision bearings

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

(3) analyze the material type of the cage (for high-speed rotation, it's impossible to have the right quality. It's equivalent to using copper alloy or phenolic resin to cut the cage. In addition, there are synthetic resin molded cages suitable for high-speed rotation with its estimated global TPE sales of about US $16.7 billion)

(4) analyze the lubrication method (adopt the circulating lubrication suitable for high-speed rotation, and judge whether the displacement control accuracy of the actuator is suitable for lubrication methods such as lubrication, spray lubrication, oil mist lubrication and oil-gas lubrication according to the calculated displacement
