Torsionally rigid couplings : ARPEX ARS-6

ARPEX® all-steel coupling, ARS-6 series Universally applicable maintenance-free all-steel coupling for the use at low up to average speeds with a permissible angular misalignment of up to 0.7°.
Advantages :
- Compensates radial, angular and axial shaft misalignments.
- Torsionally rigid and without torsional backlash.
- Suitable for any direction of rotation.
- Maintenance-free and wear resistant.
- No lubrication required.
- Easy to assemble.
- Nearly vibration-free.
- Low restoring forces.
- Modular construction system – technical solutions possible by combination of standard components.
- Approved for use in hazardous locations, zones 1 and 2.

Designs :
- With fixed and variable lengths of spacers.
- With Composite spacers (extremely light – up to 80% lighter than comparable steel couplings).
- With clamping hubs (flexible clamping joint).
- With integrated limitation of axial play.
- With integrated vertical support for vertical installation.
- With AKR torque limiter (see special brochure K 4311).
- With sliding hubs.
- With shear pin / tie bolt coupling.
