Rigid shaft couplings are essential components in mechanical power transmission systems where precise alignment, high rigidity, and zero motion loss are required. Apexcoupling is a professional China-based manufacturer specializing in high-performance rigid shaft couplings, supplying both standard products and customized solutions to global industrial customers.

This series of rigid shaft couplings is manufactured from high-strength aluminum alloy, offering excellent mechanical strength, lightweight structure, and long service life. Unlike flexible couplings, rigid shaft couplings are designed to transmit torque without angular, radial, or axial compensation, making them ideal for applications that demand absolute shaft alignment and maximum torsional rigidity.

Apexcoupling rigid shaft couplings use a precision clamping screw tightening method, ensuring strong shaft fixation without backlash. The clamping structure prevents shaft damage while delivering stable torque transmission and eliminating power loss during rotation. These rigid shaft couplings are suitable for both forward and reverse rotation and perform reliably under high-speed operating conditions up to 9400 r/min.

With an allowable torque range from 5 N·m to 115 N·m, these rigid shaft couplings are widely used in asynchronous motors, stepping motors, automation equipment, and industrial machinery. The rigid structure ensures consistent performance in applications where vibration reduction is not required but positioning accuracy is critical.

As a direct factory supplier, Apexcoupling offers OEM, ODM, and OBM services for rigid shaft couplings. Keyways are available upon request, and bore sizes can be customized to meet specific motor shaft requirements. Our rigid shaft couplings are manufactured under strict quality control systems and comply with ISO9001 standards, ensuring stable quality for export markets.

These rigid shaft couplings are widely applied in manufacturing plants, machinery repair shops, food and beverage factories, construction works, energy and mining industries, and automation systems. Their high torque capacity, high rigidity, and zero backlash characteristics make rigid shaft couplings an ideal choice for precision-driven equipment.

By choosing Apexcoupling rigid shaft couplings, customers benefit from factory-direct pricing, flexible customization, fast delivery, and professional technical support. Our goal is to provide reliable rigid shaft couplings that help global customers improve transmission efficiency and equipment stability while reducing maintenance costs.
