KTR-SI Compact

The KTR-SI Compact is a robust overload system with a decreasing spring characteristic line, which offers overload protection up to 3,100 Nm. The KTR-SI Compact has precise backlash-free torque transmission and a ball bearing connection flange. Its hardened ratchet surfaces provide a long service life.

Properties:

  • Backlash-free overload system with decreasing spring characteristic line
  • Overload protection up to 3,100 Nm
  • Robust design
  • Precise, backlash-free torque transmission
  • Ball bearing connection flange
  • Hardened ratchet surfaces provide for a long service life
Please refer to the respective data sheet for the properties of the individual couplings.

More informations

The KTR-SI Compact with ROTEX® GS is an overload system combined with the vibrationdamped ROTEX® GS. It is a backlash-free and frictionally-locking shaft-hub connection guaranteeing overload protection of up to 3,100 Nm. The KTR-SI Compact is also available with the torsionally stiff RADEX®-N or RADEX®-NC. The NC with TOOLFLEX® features a frictional-locking clamping hub or taper hub.

The KTR-SI Compact flange type is a torsionally stiff overload system up to 740 Nm. Thanks to its decreasing disk spring, this overload clutch is characterised by its low residual moments and high re-engagement accuracy.

It can also be combined with the backlash-free ROTEX® GS. The KTR-SI Compact flange type is axial plug-in and available in a ratchet and also synchronous design. It can optionally be supplied with a friction-locking shaft-hub connection or with a feather key connection.
