What is the function of the ball bush bearing?

Lining is a lining inside; a sleeve is a cylindrical hollow part. For example, if a hole matches a shaft, the hole rotates on the shaft. If it takes a long time, it will wear out. You can add a ball bush bearing to the hole first. If the sleeve is worn out, you can change the sleeve instead of the entire (hole) part. . The iron hole is lined with copper sleeve and graphite sleeve, which can also improve the lubrication conditions.

Ball bush bearing can also be another name for sliding bearings (commonly known as "tiles", "shaft sleeves"). Different materials are used for bushings, and their sizes, suitable working environment and pressure-bearing capacity are different; different from ball bearings, it uses different Based on the principle of different sliding friction coefficients between materials, reasonable materials are selected to reduce the friction between the shaft and the supporting surface while ensuring the bearing capacity between the shaft and the supporting surface.

The flexibility of the ball bush bearing is relatively high, and it can play a lot of roles. Generally speaking, the bushing is a kind of component that protects the equipment. The use of bushings can reduce equipment wear, vibration and noise, and has an anti-corrosion effect. The use of the bushing can also facilitate the maintenance of mechanical equipment and simplify the structure and manufacturing process of the equipment. The role of the bushing in actual work has a lot to do with its application environment and purpose. In the field of valve application, the bushing is installed in the valve cover to cover the valve stem, so as to reduce the leakage of the valve and achieve the sealing effect. In the bearing application field, the use of ball bush bearing can reduce the wear between the bearing and the shaft seat, and avoid the effect of increasing the gap between the shaft and the hole.

Features of ball bush bearing
The bush bearing is an extremely small linear motion guide machine that rotates with the shaft and makes infinite linear motion in the direction of the shaft while contacting, and the shaft diameter is 3~5mm.

Features of ball bush bearing:
1. Low frictional resistance: The steel ball can perform stable linear motion with extremely small frictional resistance due to the correct orientation of the retainer.
2. Stainless steel: stainless steel series are also available, suitable for applications requiring corrosion resistance.
3. Exquisite design: extremely small in size and can be designed in exquisite mechanical equipment.
4. Abundant changes: In addition to the standard type, there are also a series of high rigidity long types, which can be selected according to the purpose.

The function of the bushing is to prevent the shaft from directly rubbing against the seat hole, reducing the damage to the shaft and protecting the shaft. The reciprocating and rotating movement of the shaft in the bushing is as if a thick layer is covered on the shaft. Layer of wear-resistant graphite.
