Claw type surface-to-surface design provides effective protection, vibration damping, and shock absorption during operation. The circumferential offset design with quincunx elastic body arrangement avoids stress concentration during installation deviations.
Effectively compensates for axial, radial, and angular displacement. Unlike traditional column pin couplings that operate under shear stress, our claw-type couplings work under extrusion pressure, enabling higher load capacity, superior wear resistance, and extended service life.
- Simple structure with stable performance and reliable operation
- Three-component design for easy installation and maintenance
- Multiple material options for hub and elastic body to suit various environments
- Surface-matching claw type design with involute arc elasticity for higher torque transmission
- Insulating elastic body pads prevent metal-to-metal contact, eliminating lubrication requirements
Standard sizes: Gear 3J, 4J, 5J, 6J, 7J, 8J, 9J, 10J, 11J
Custom sizes available according to buyer's drawings and specifications
