SK Safety Coupling
SK Safety Coupling
The R+W BK safety coupling offers reliable overload protection for industrial applications. With precisely adjustable torque limitation, it protects machines from damage in the event of overloads or collisions. The low-inertia BK safety coupling disconnects the drive train in fractions of a second and ensures maximum safety and machine availability. Thanks to its compact design and high power density, it can be easily adapted to existing systems. Various designs allow flexible adaptation to a wide range of applications. The BK safety coupling from R+W impresses with its durability, maintenance-free design and first-class quality – optimum protection for your machines.
