Product catalog summary

Overview of R+W Safety Couplings (TORQSET®):
R+W Safety Couplings, known as TORQSET®, are engineered for torque ranges between 200 and 250,000 Nm. They feature a fit clearance of 0.02 - 0.07 mm and can operate in temperatures from -30 to +120°C. Special features include automatic re-engagement and optional ATEX certification for hazardous environments. The standard disengagement is full with a manual reset.

Model Features:

ST1: Offers simple keyway mounting for indirect drives, providing precise overload protection and torsional stiffness. Available in sizes 2 to 40, with adjustment ranges from 0.2 to 45 KNm.
STR: A robust version with keyway mounting, designed for high durability and reinforced bearings. Available in sizes 2 to 250, with adjustment ranges from 0.2 to 250 KNm.
STN: Includes a conical clamping ring for high shaft clamping pressure, available in sizes 2 to 160, with adjustment ranges from 0.2 to 165 KNm.
STF: Features flange mounting on both sides, suitable for torque transducers and high-speed applications, available in sizes 2 to 40, with adjustment ranges from 0.2 to 45 KNm.

Technical Specifications:

Constructed from hardened steel with a nitrocarburized surface for enhanced durability.
Design includes coupling hubs with keyway or conical clamping connections, output flanges with fastening threads, and integral bearings.
Safety elements are evenly spaced and externally adjustable for precise overload protection.
Supports various mounting options, including keyway, conical clamping, and flange mounting.

Performance Parameters:

Maximum speeds range from 1200 to 9000 rpm depending on the model and size.
Allowable maximum radial forces range from 5 KN to 240 KN, with larger loads possible using special bearings.
Moment of inertia and weight vary significantly across models and sizes, reflecting diverse application capabilities.

Applications and Options:
These couplings are suitable for a wide range of industrial applications requiring precise torque control and overload protection. Optional accessories and special solutions are available to tailor the couplings to specific needs.

Adjustment Wrench Specifications:
Adjustment wrenches are available in sizes 10, 15, 30, and 70, each with a specific order number. These tools are essential for engaging and disengaging elements.

Switch Plate Information:
Switch plates can be requested for all sizes and series. It is crucial to test switches for proper functioning after mounting with safety coupling.

Proximity Switch (E-Stop Function):
Order Number: 650.2703.001
Technical Data: Voltage range of 10 to 30 V DC, max output current of 200 mA, max switch frequency of 800 kHz, temperature range from -25° to +70° C, protective system IP 67, normally open switch type, and max detection gap of 2 mm.

Mechanical Limit Switch (E-Stop Function):
Order Number: 618.6740.644
Technical Data: Max voltage of 250 V AC, max constant current of 2.5 A, protective system IP 65, opener contact system, temperature range from -30° to +80° C, and actuation via a metal plunger.

ATEX Limit Switch (E-Stop Function):
Order Number: EEX. 1624.004
Technical data is available upon request. The switch diagram indicates a 2-channel isolating switching amplifier.

General Recommendations:
Ensure all switches are 100% tested for proper functioning after installation with safety couplings. The actuation path should be approximately 0.1-0.2 mm for optimal performance.
