R+W SK2 60 102 W torque limiter, adjustment range: 25-80 Nm, stainless steel and aluminium
HV3020121501The R+W SK2 60 102 W safety coupling is a precision overload protection device, also known as a torque limiter or overload clutch. Part of the SK2 series from R+W Antriebselemente GmbH, a German manufacturer internationally recognized for high-performance couplings and safety components, it is designed to protect machinery from damage caused by sudden overloads.
Manufactured from stainless steel and aluminium, this model combines strength, corrosion resistance and low weight. It features an adjustable torque range of 25–80 Nm with a maximum torque of 80 Nm, making it suitable for medium torque drive applications. With a length of 102 mm and a compact outer diameter of Ø32 mm, the SK2 60 102 W is designed for space-sensitive installations. The coupling includes a Ø25 mm H7 bore with keyway (D1) and a Ø25 mm H7 bore (D2), ensuring secure and precise shaft mounting. Classified as coupling size 60, it integrates seamlessly with other R+W drive elements for reliable safety performance.
