HKK HRC Jaw coupling

These are  low cost, no fuss shaft couplings. Type HKK jaw shaft couplings are available in steel, cast iron and aluminium and can come with ATEX approval if requested. Type HRC jaw couplings combines the benefits of an elastomeric coupling with those of a taper lock bush.

The curved jaw coupling design consists of an elastic “spider” and two hubs. The spider, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. These spiders allow the user to customize the jaw coupling’s performance. Selecting a soft spider will give the jaw coupling the greatest dampening characteristics, while a hard spider will provide the greatest torque capacity and strength. The jaw coupling can also be considered as a fail safe device. If the spider fails, the jaws of the two hubs interlock allowing direct power transmission, allowing the application to be safely shut down for maintenance.

To suit shaft sizes from 6mm to 100mm or supplied pilot bored.

Type HCC Collars are designed for easy assembly, adjustment and disassembly. The single component collars loack around the axis of the shaft with an even distribution of clamping force. The collars can be used on shaft sizes from 3mm to 50mm diameter and are available in both steel and stainless steel
