The cross slide coupling uses polyurethane plastic as the elastic element and the two-half coupling body is tightly combined. The main body is made of 45# steel, and there are also stainless steel bodies, which can be customized according to customer requirements. The material is well-proportioned to avoid inconsistent materials. Uneven rotation caused by symmetrical.The surface is blackened and anti-rust treatment. The intermediate polyurethane plastic element is formulated with a unique formula, which has high wear resistance, high temperature resistance, good toughness, and stable and durable quality with ordinary plastic parts (comparison of advantages and disadvantages). The shape of the plastic element is Star.

　　The Oldham coupling is composed of two shaft sleeves and a slider.As a torque transmission element, the slider is usually made of engineering plastics. Under special circumstances, other materials, such as metal materials, can be selected.The sliding block is connected with the shaft sleeves on both sides by 90° oppositely distributed clamping grooves on both sides, so as to achieve the purpose of transmitting torque.The sliding block and the shaft sleeve are matched with a slight pressure, which enables the coupling to run with zero clearance during the operation of the equipment.As the use time increases, the slider may lose its recoilless function due to wear, but the slider is not expensive and easy to replace, and it can still play its original performance after replacement.
