Model SK1 Safety Coupling,

Precision Torque Limiters Series SK1 in Stainless Steel

News Release from: R+W Coupling Technology

Taking up the challenge for greater technical demands in modern machine design and construction, R+W has developed the unique reliable Model SK1 Safety Coupling in Stainless Steel. Ideal for clean room or wash down applications in the packaging, food processing, and medical industries.

Torque overload protection is often overlooked in machine design until something jams resulting in expensive damage and down time. The R+W Series SK1 safety coupling was developed specifically for this purpose. It uses a reliable ball detent system that is absolutely backlash-free and will disengage within 1 to 3 milliseconds when an overload is detected.

Four versions are available including a single position, multi-position, load holding, and free wheeling. These couplings are preset in the factory to a customer specified disengagement torque and can be adjusted in the field after installation.

The SK1 can be integrated into timing pulleys, sheaves, and sprocket wheels for a torque range of 0.2 to 1500 Nm (1.8 to 13,275 in. lbs.). It is shaft mounted using a clamping hub, taper conical sleeve or a pure keyway connection for shaft sizes from 4 to 70 mm (0.16 to 2.76 in.).
