A gear type coupling is a high-performance rigid shaft connection solution designed for transmitting large torque under demanding industrial conditions. Manufactured by Apexcoupling, a powerful coupling factory in mainland China, this gear type coupling is engineered for durability, precision, and long service life in heavy-duty power transmission systems.

This gear type coupling adopts a curved tooth (crowned gear) design, which allows small angular and radial displacement while maintaining excellent torque transmission capability. Compared with straight-tooth designs, the crowned teeth structure of the gear type coupling reduces edge stress, improves load distribution, and significantly extends operating life.

The coupling body is made from high-strength S45C steel, offering superior wear resistance and mechanical strength. With a rated torque of 300 N·m and an allowable torque range up to 12000 N·m, this gear type coupling is suitable for pumps, compressors, gearboxes, mixers, conveyors, and heavy industrial machinery. The rigid structure ensures zero backlash transmission, making the gear type coupling ideal for applications requiring precise rotational control.

To enhance reliability, the gear type coupling supports multiple surface treatments such as black oxide, zinc plating, nickel plating, and phosphating. These treatments improve corrosion resistance and adapt the gear type coupling to harsh working environments. The bore can be customized into key slot, hexagonal, square, or spline shapes with H7/H8 tolerance, ensuring perfect shaft matching.

Installation flexibility is another advantage of this gear type coupling. The keyway and setscrew tightening method guarantees secure shaft locking and prevents slippage under high load. The integral sealing structure design helps retain lubricant, reduce component count, and improve the overall operating stability of the gear type coupling during long-term continuous operation.

As a professional manufacturer and exporter, Apexcoupling supplies both standard gear type coupling models and customized gear type coupling solutions under OEM, ODM, and OBM cooperation. With a low MOQ of just one piece, international buyers can easily test quality and performance before large-scale procurement.

Choosing Apexcoupling means selecting a reliable gear type coupling supplier focused on quality control, engineering support, and long-term B2B cooperation for global industrial markets.
