What’s the action of ball bearing sleeve?Why we use it together with bearing?

The role of ball bearing sleeve
The flexibility of the ball bearing sleeve is relatively high, and it has many functions. In general, the ball bearing sleeve is a type of component that protects the equipment. The use of ball bearing sleeve can reduce equipment wear, vibration and noise, and have anti-corrosion effects. The use of ball bearing sleeve also facilitates the maintenance of mechanical equipment and simplifies the structure and manufacturing process of the equipment.

The role of the ball bearing sleeve in actual work has a lot to do with its application environment and purpose. In the field of valve applications, the ball bearing sleeve is fitted inside the valve cap to trap the stem, thereby reducing valve leakage and achieving sealing. In bearing applications, the use of a bushing can reduce the wear between the bearing and the shaft seat and prevent the clearance between the shaft and the hole from increasing.
Bush material
The material of the ball bearing sleeve is mostly soft metal, rubber, nylon and non-metal polymer, etc. The texture of these materials is relatively soft and the cost is low. In a variety of harsh working environments, the bushes are subjected to vibration, friction and corrosion to protect the wrapped parts, and the ball bearing sleeve  itself are easily replaced after being damaged, the cost is low, and the economy is good.

Bushing selection factor
The scope of use of ball bearing sleeve is large and there are many types. To select a suitable bushing, it is necessary to consider its purpose of use. Different types of bushings are selected for different working conditions. The main considerations in the selection of the ball bearing sleeve are the pressure, speed, pressure velocity product and load nature of the bush. In addition, whether or not the bushing is lubricated and lubricated also determines its effectiveness and longevity.
