 Cylinder manufacturer's direct pin


Hydraulic cylinder , also called oil cylinder for short, is the main executive component in mechanical engineering and can complete many actions; The main factor affecting the quality of oil cylinder is the material of support bushing. Generally, nylon 1010 and polyoxymethylene are commonly used materials. The following describes these two materials in detail, and introduces their performance characteristics, application range and processing methods, as detailed below.

Oil cylinder manufacturer The middle support bushing is inserted at the groove of the inner diameter of the guide sleeve to guide and support the piston rod. The optimal design clearance between the inner diameter and the outer diameter of the piston rod is 0.08-0.16mm. When it is less than 0.08mm, the movement resistance of the piston rod is large, the oil cylinder trembles, and the wear of the support bushing is accelerated. In serious cases, there is abnormal noise, and the support function is lost; When the clearance exceeds 0.16mm, it is easy to have eccentric wear with the piston rod, and the bushing is forced on one side, resulting in oil cylinder leakage and oil in the piston rod.

The outer diameter of the support bushing is in contact with the inner diameter of the cylinder barrel of the oil cylinder, and the preferred design clearance is 0.1-0.19mm. When it is less than 0.1mm, the movement resistance of the piston rod increases, and it can not maintain uniform movement, especially when the oil temperature is high. The bushing can not play a supporting role, and the baffle plate on the piston rod or the outer edge of the piston is easy to scratch the inner wall of the cylinder barrel, which may lead to scrapping of the cylinder barrel in serious cases.
