Claw type surface-to-surface design provides protection functions, with effective damping for vibration and shock reduction during the running-in process. The claw type teeth two sleeves are offset circumferentially, with quincunx elastic body involute in the gap. This design avoids stress concentration during small installation deviations. Effectively compensates for axial, radial, and angular displacement. Compared to traditional column pin coupling elastomers with large volume and shear effects that are prone to damage, the new claw type couplings operate under extrusion pressure only, enabling them to withstand greater loads, offer better wear resistance, and provide longer service life. Suitable for both horizontal and vertical installation.
CJ Series Coupling Characteristics
- Simple structure, stable performance, and reliable operation
- Three-component structure for easy installation and maintenance
- Multiple material options for hub and elastic body to ensure stable performance in various environments
- Surface matching claw type shaft hub with involute arc elasticity avoids stress concentration, transmits higher torque effectively, and offers superior abrasion resistance with extended service life
- Small protuberance pad on elastic body isolates metal shaft hub contact, providing effective insulation without requiring lubrication
Physical Properties
Manufactured by injection molding using high-quality polyester or CSM/SBR molds. Specifically designed for all types of metal shaft couplings with excellent performance characteristics including high tensile strength, superior wear resistance, high elastic resilience, water resistance, oil resistance, excellent fatigue resilience, and high impact resistance. We maintain complete mold sets and supply the full range of GR, GS, MT, Hb, HRC, L, NM, and Gear J series couplings with high quality and extensive experience. Suitable for all types of industrial metal shaft couplings.
