Air motors from Huco Dynatork combine precise positioning and efficient operation with the ability to withstand the rigours of 100 per cent caustic washdown environments.

As standard, the motors are able to operate totally immersed in water, so even high-pressure washdowns can be accommodated.

With acetal housings also available, the motors are able to withstand most caustic acids and chlorinated sanitisers used in the food industry.

The free-floating piston design of the air motor means that it consumes up to 80 per cent less air than a conventional vane motor and provides start/stop performance characteristics similar to those of a stepper motor, performing in constant start/stop applications under load.

In operation, air up to 100psi is supplied to each of three pistons in turn via an integral rotary valve.

The free-floating pistons transmit torque on start-up that can be adjusted via a pressure regulator.

The result is high torque at variable low speed, combined with very low noise.

Huco Dynatork offers a range of air motors in different sizes, with maximum torques of up to 16 or 550Nm with a gearbox.

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.
