JQ Factory price alloy steel clamp shaft coupling for Stepper & Synchronous motor.

The clamp coupling uses two clamps split in the axial direction to connect two-axis by clamped with bolts. The torque is transmitted by the friction between the surfaces of the two coupling halves, and the flat key plays a  auxiliary connecting role.

Product Description

Brief introduction :

 There are multiple spacers in the clamp coupling . Among those spacers same like the slider coupling, due to its elasticity, it has the effect of buffering and damping, so it is often used in the case of strong vibration. The performance limit temperature of the elastomer determines the use temperature.So it hasgood versatility and wide application range.


Radial and angular axis offset performance requires that auxiliary man-hours be minimized. It through press to make the spacer and the sleeve on both sides coincide. Then realize the connection of two half couplings.

coupling parameters


Good vibration damping performance,

Simple structure,

Stable and reliable work,

No noise,

No lubrication,

Simple maintenance,

Easy to disassemble and installation

Good manufacturability and low cost,

Can be derived into a variety of structural forms,


(1) The alignment accuracy of two axes is low;

(2)  The shape is more complex ,the manufacturing and the balancing is low ;

(3) It is suitable to low speed and stable load,generally,the linear velosity shouldn't more than 5m/s,if exceed 5m/s,the balance verification is reqiured.

How to improve balance?


In order to improve the balance, the bolts should be installed between normal and reverse phases.
