Safety Couplings

Our safety/overload couplings operate on the ball-in-detent principle, ensuring absolute backlash-free performance due to KBK’s unique ball arrangement as the locking mechanism. Each safety coupling is precisely adjusted and tested to meet the customer’s specified release torque. After initial use, the release torque can be continuously adjusted as needed.

KBK safety couplings are available in four functional modes and come in multiple configurations for both direct and indirect drives. In addition to our extensive standard product range, we also offer custom replicas of existing safety couplings, including those from GERWAH and other brands.
