Shaft sleeve: The shaft sleeve is a cylindrical mechanical part that is inserted on the rotating shaft and is an integral part of the sliding bearing. Its main function is to protect the shaft, avoid direct wear and reduce maintenance costs. The sleeve is usually of an integral structure and is a relative movement between the shaft and the sleeve when rotated.
Beaders are more durable than sleeves. The main difference between bearings and bushings is that the bearing has smaller resistance, higher speed, lower power consumption and longer life; while the bushing has greater resistance, lower speed, higher power consumption and shorter life.
Definition and uses of bearings and bushings
Bearing: Bearing is an independent component used to support mechanical rotating bodies, reduce the friction coefficient during movement, and ensure its rotation accuracy. Bearings are divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, the radial size, vibration and noise are higher, and the price is also higher.

Advantages and disadvantages of bearings and bushings
Bearings:
Advantages: Small resistance, high speed, low power consumption, and long life.
Disadvantages: Large radial size, high vibration and noise, and high price.
Bush:
Advantages: Simple structure and low cost.
Disadvantages: Large resistance, low speed, high power consumption, and short life.
