Power transmission coupling lasts up to thirty times longer

21 March 2011

The Sure-Flex brand of elastomeric couplings, which is now available ex-stock from Huco Dynatork, are suitable for applications where low cost, high flexibility and vibration dampening are primary concerns. Quick and easy installation is assured as the design has no bolts, gaskets, covers or seals; and no special tools are required. Alignment is simply checked with a straight edge placed against the outside of the flanges.

These couplings need neither lubrication nor maintenance as the components are wear-free and the design ensures no ingress of abrasive dirt and moisture. Sure-Flex couplings use a synthetic rubber or Hytrel thermoplastic flex element to transmit torque – up to 8.2kNm – and to accommodate shaft misalignment. Indeed, they have exceptional torsional flexibility and their 4-way flexing action absorbs shock, vibration, misalignment and end float.

‘Fatigue test to failure’ results confirm that the Sure-Flex polymeric flex elements last twice as long as their nearest competitive coupling and up to 30 times longer than the remaining competitive models.
