Product Description
GD/G Type Cross Universal Joint Coupling – Single / Double Section, 42CrMo Alloy Steel, 30mm Bore
Factory Direct from Guangdong, China | 42CrMo Alloy Steel | Single & Double Section | H7 Precision Bore | High Torque | Low Clearance | FA Factory Automation Standard | Custom Sizes Available
Product Overview
The GD/G Type Cross Universal Joint Coupling from Apexcoupling is a high-performance power transmission component designed for angular misalignment compensation and reliable torque transfer. As a CPCA/CPCW universal joint type, this coupling is manufactured in Dongguan, Guangdong, China, and is widely used in factory automation, CNC machinery, packaging equipment, and general industrial drive systems.
The coupling is made from 42CrMo alloy steel – a high-strength material known for excellent toughness, superior wear resistance, weldability, high-temperature resistance, and corrosion resistance. The H7 precision inner bore is ground for high concentricity, minimal clearance, and reduced noise during high-speed operation. All bores are precision-machined on imported machining centers to ensure tight tolerances and superior accuracy.
The GD/G series is available in single-section (G) and double-section (GD) configurations. The built-in bearing and locking pin in the sleeve allow for continuous operation within a 30° angle, with a maximum angle of 45° per joint. The material can also be 304 stainless steel, typically blackened for a standard finish, with optional nickel plating, galvanizing, or polishing upon request.
As a FA factory automation standard universal joint, this coupling is kept in large stock for fast delivery. It offers quick response when rotating clockwise or counterclockwise and boasts high transmission efficiency. Custom sizes and configurations are available upon request.
