Co-Axial Linear Drives – UCC Series

Co-Axial Drives consist of two integral elements; a pneumatic drive unit to provide power and an integrated, closed circuit hydraulic drive to provide accurate speed control.

UCC Drives are used extensively in the field of automation, where traditionally, hydraulic, mechanical or electrical drives would have been used for the control of linear movement and positioning.

Accurate positioning and speed control is ensured by a closed hydraulic circuit within a coaxial tube. Although power is provided by compressed air speed and positional accuracy are unaffected by the compressibility of the air. UCC Drives offer a clean, environmentally friendly, pollution free solution.

Control is simple, with only two compressed air connections to power operate the unit. Options also include positional feedback for PLC interfacing. UCC Drives are compact and easy to install, and are also relatively simple to maintain. By reducing the number of components and simplifying the complexity of the system we have increased the level of overall reliability. All UCC Drives are 100 % tested.

UCC Drives are designed in accordance with ISO standards making standardization and interchange ability with pre-existing systems simple. Ordering is also made simple using a single code which is dedicated to the particular User.

UCC Drives are not just a component but a complete control solution.
