SL cross slider coupling, also known as metal slider coupling, its slider is circular, made of steel or wear-resistant alloy, suitable for transmission with low speed and high transmission torque.

Cross slider coupling parts can be made of 45 steel, the working surface needs heat treatment to improve its hardness, and Q275 steel can be used when the requirement is low, without heat treatment. In order to reduce friction and wear, oil should be injected into the oil hole of the middle disc for lubrication. Cross slider coupling, also known as metal slider coupling, its slider is circular, made of steel or wear-resistant alloy, suitable for transmission with low speed and high transmission torque. The cross slide coupling consists of two half couplings with grooves on the end face and a middle disk with convex teeth on both sides. Because the convex teeth can slide in the groove, the relative displacement between the two axes during installation and operation can be compensated.

Because the semi-coupling and the middle disc form a moving pair and can not rotate relatively, the angular velocity of the active shaft and the driven shaft should be equal. But when there is relative displacement between the two axes, the centrifugal force of the middle disk will be very large, which will increase the dynamic load and wear. Therefore, it should be noted that the working speed should not be greater than the prescribed value. This kind of coupling is generally used for rotating speed n < 250 r/min, the stiffness of the shaft is large, and there is no severe impact.
