These torsionally stiff, light weight couplings are capable of transmitting high torques at high speeds while accepting significant levels of angular, radial, and axial misalignment. They are easy to install, suitable for hostile environments, require no lubrication and feature a high torque to weight ratio. Specific designs are available which meet the customer’s exact requirements. Standard units are compliant with API 671 (American Petroleum Institute) and ATEX 94/9/EC.

•	No maintenance
•	Standard and reduced moment designs available
•	Capable of being torsionally tuned to suit specific machinery requirements
