DSS or DSR: Balls or Rollers torque limiters 
DSS / DSR torque limiters are overload protection devices with either ball or roller transmission, which disengages fully at the pre-set peak torque. The torque is steplessly adjustable by altering the spring pressure.
DSS / DSR Features
- Precise torque setting by adjusting the radially balanced locking nut
-
The innovative regulation of the nominal torque by measuring the “H” dimension allows for immediate coupling calibration. Equidistant re-engagement in phase or at 360°
-
Available with electromechanical switch / proximity for the transmission disconnection
-
Immediate intervention for an improved reaction compared to electronic systems
-
Maintenance-free for long lasting high reliability
-
Suitable for oily and wet environments
DSS / DSR – Available on Request
- Complete with transmission gear, fully turned and mounted (plate wheel, pulley, gear pair)
-
Possibility to use helical springs for low intervention torques
-
Connections with bore and keyway, locking assembly possible
-
Version with personalized re-engagement in phase 30°, 45°, 60°, 90°… possible
Main Applications
- Packaging and wrapping machines
-
Labelling machines
-
Bottling machines
-
Conveyors
DSS / DSR Advantages and Benefits
- Protects the gearbox from jamming due to foreign matters
-
Protects packages from squashing and deforming
-
Protects the product handling elements from accumulations
-
Maintains the timing between driver and driven after an overload
