Key Features
- Specifically designed for air compressors
- Manufactured on serious production lines for consistent quality
- Premium quality materials at competitive prices
- Custom packaging options available
- OEM services provided with A&V quality checks
Design Advantages
The claw-type surface-to-surface design provides effective vibration damping and shock absorption, reducing wear during operation. The circumferential offset of claw-type teeth with quincunx elastic body arrangement compensates for installation deviations while avoiding stress concentration.
Compared to traditional column pin couplings, our design offers superior load capacity, better wear resistance, and longer service life. Suitable for both horizontal and vertical installations.
Product Characteristics
- Simple, stable design for reliable operation
- Three-component structure for easy installation and maintenance
- Multiple material options for hubs and elastic bodies
- Involute arc elasticity design for higher torque transmission
- Elastic body protuberance pads prevent metal-to-metal contact
