Heli-Cal Shaft couplings are an essential connection in any rotary device without loss of registration under load. The original helical beam style product compensates for angular, parallel and skewed shaft misalignments whilst delivering zero backlash, constant velocity shaft through its single piece construction. Ideal for servo, stepper and electric motor connection they are available in Stainless Steel and Aluminium as standard supplied in both metric and imperial bores from 3mm up to 38mm.

Shaft couplings manufactured from plastic offer an excellent low cost equivalent to aluminium shaft couplings especially where the torque requirement is lower.

This product range offers you a quality range of plastic injection moulded shaft couplings giving high torsional stiffness combined with exceptional durability to shaft misalignment. There are two basic designs called UJ and GJ. Type UJ is for lighter usage and smaller angular and parallel shaft offsets, whilst type GJ, with its two flexible elements, is ideal for medium usage.

Abssac's X-Slot shaft couplings bridge the gap and offer a cost-effective balance between couplings that are too stiff radially and those not stiff enough torsionally for servo type applications.

The X-Series coupling incorporates two flexible element sets-combining greater end-to-end rotational accuracy with radial accuracy in one design. In durability testing, the couplings have been subjected to parallel offsets of up to five times the rated value and tested to failure. Even when tested for tens of millions of cycles at these exaggerated offsets the coupling exhibited an exceptional performance capability.
