take Hydraulic cylinder The earrings on the machine and the earrings on the machine are connected by a pin shaft, so that the hydraulic cylinder can swing freely in a certain plane, and the force is in a plane. If the earrings have a ball hinge, it can be within ± 4. The cone angle changes direction internally.        

1. The earrings at the tail of the hydraulic cylinder can be single earrings, double earrings, or single earrings or double earrings with joint bearings.       

2. Pay attention to the load direction of the hydraulic cylinder installed in the ear ring type. When the hydraulic cylinder is installed in the ear ring type, the load is allowed to swing in a considerable range in one direction. However, swing or string motion is not allowed in the other direction perpendicular to it, otherwise, the hydraulic cylinder will be subjected to the bending load with the earring as the fulcrum. Sometimes, the thread at the head of the piston rod breaks due to the bending of the piston rod, and the internal surface of the cylinder barrel is easily damaged due to the reciprocating motion of the piston rod when it is bent, Oil cylinder manufacturer It is necessary to avoid uneven wear of guide sleeve, uneven sealing and leakage.
