The main functions of adding shaft sleeves between bearings include reducing wear, extending service life, improving equipment operation stability, and reducing energy consumption. ??
Reduce wear and extend service life: Shaft sleeves can reduce friction between bearings and shafts, reduce wear, and thus extend the service life of bearings. Under load, excessive metal contact may occur between the bearing and the shaft, leading to increased wear. Adding a shaft sleeve can act as a divider, reducing this contact, lowering wear, and extending the service life of the bearing.
Improve the stability of equipment operation: The shaft sleeve can absorb vibration, improve the stability of equipment operation, and reduce faults and damage caused by vibration. In mechanical rotation, the shaft sleeve can fix the position of the shaft and prevent directional deviation due to vibration and other reasons during movement.
Reduce energy consumption: The shaft sleeve can provide lubricant, reduce energy consumption, and make the equipment operate more smoothly. Under appropriate lubrication conditions, the shaft sleeve can reduce friction, lower energy consumption, and improve the operational efficiency of the equipment.
Easy to install and maintain: In some cases, the bearing sleeve can be adjusted to loosen or tighten, which relaxes the machining accuracy of many boxes and improves work efficiency. In addition, the bearing sleeve also overcomes the axial movement of the bearing, making it easy to install and maintain.
