Product Description

Couplings are essential power transmission components used to connect two shafts and transmit torque. They are widely applied in industrial machinery, automation systems, pumps, valves, gearboxes, machine tools, blowers, and various mechanical drives.

We supply a full range of couplings including flexible couplings, rigid couplings, gear couplings, universal joints, disc couplings, and more—covering torque transmission, vibration damping, and misalignment compensation for different working conditions.

As a professional supplier, we support multiple specifications, materials, and OEM customization, fully compatible with mainstream international models.

Product advantage

High machining precision: CNC turning, grinding, and dynamic balancing ensure stable transmission.

High reliability: Suitable for high torque, heavy-duty, and long-duration operation.

Excellent misalignment compensation: Works for axial, radial, and angular offsets.

Premium materials: 45# steel, 40Cr, aluminum alloy, stainless steel, alloy steel optional.

Long service life: Wear-resistant elastomers, bushes, and gear teeth for reduced maintenance.

Full model coverage: Supports standard and customized couplings according to customer drawings.
