Product Advantages

The CJ series coupling features a simple yet stable design with three-component structure for easy installation and maintenance. The involute arc elasticity design avoids stress concentration while effectively transmitting higher torque. The elastic body's small protuberance pad isolates metal contact, providing effective insulation without requiring lubrication.

Manufactured through injection molding with high-quality polyester or CSM/SBR materials, these couplings offer exceptional performance characteristics including high tensile strength, wear resistance, elastic resilience, and resistance to water, oil, and fatigue. Suitable for all industrial metal shaft coupling applications.
