Product Details Supplier Info More products

The Sure-Flex brand of elastomeric couplings is available from Huco Dynatork 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, so no special tools are required.

Alignment is simply checked with a straight edge placed against the outside of the precision-machine flanges.

Characterised by their clean, dependable and quiet performance, these products need neither lubrication nor maintenance as the components are wear-free and the design is immune from the 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.

They are claimed to have exceptional torsional flexibility and their four-way flexing action absorbs virtually all types of 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.

As a result, these couplings are suited for rotating machinery across a range of industries.

Typically Sure-Flex couplings are found in systems involving pumps, fans, blowers, compressors, mixers, electric motors and conveyors.

Flex elements are available in a choice of four materials or compounds and in various shape configurations to suit the application.

Spacer, bushed hub and clamping hub designs complete the range – the most popular sizes of which are available from stock.

Huco Dynatork is a world-class manufacturer of flexible couplings.

Whether the need is for high torsional stiffness, generous misalignment capability, high-speed operation or a capacity for operating in push/pull mode, Huco Dynatork can help. And if your requirements fall outside our standard range, we offer a customised service and cost-efficient small-batch production. 

Our range is highly comprehensive, comprising membrane and bellows high-performance couplings; Oldham and Uni-Lat general-purpose motion control couplings; Single-Beam, Multi-Beam and Step-Beam brands; and jaw/spider and double loop light power drive couplings. We also stock stainless steel and plastic universal joints.

Although the design and manufacture of couplings remains the cornerstone of our business, this is just one of the company's five main product groups. Huco Dynatork piston air motors is one of them, the only brand that can be used for precision motion control. 

Our quality hallmark is also impressed onto a huge range of power transmission and motion control components that have distinct design and performance benefits over other products in the market. In addition to an extensive choice of stock gears, racks, ground shafts and spline shafts, the product programme also includes the comprehensive BSA range of leadscrews and ballscrews.
