Type DSS/SG/RF 10 to 1,200 Nm

The DSS/SG/RF torque limiters give ultra-fast release on overload with zero residual torque. They suit precision machinery, particularly where running speeds and inertias are high. These torque limiters are backlash free and can be provided with locking bush shaft connection to avoid backlash in keyways. Torque range is 10 to 1,200 Nm.

High sensitivity to overloads is achieved by disc springs with negative spring rate. Torque transmission from balls in sockets is then disengaged to achieve disconnection between input and output. These torque limiters can operate in either direction of rotation. Re-engagement is a simple mechanical process.

DSS/SG/RF limiters suit offset drives or can be supplied with flexible couplings for in-line drives. Both torsionally soft and metal-disc torsionally rigid couplings are available with bores up to 70mm.

Special variants are available for volume applications.
