Hydraulic cylinders offer long working life Suitable for working pressures of up to 250 bar hydraulic cylinders feature rugged components to give a long operating life in presses, automation systems and wood working equipment. The hydraulic cylinder Division of Parker Hannifin, the world's leading manufacturer of motion and control solutions, has introduced its latest MW Series of roundline hydraulic cylinders. These cylinders are suitable for working pressures of up to 250 bar and feature rugged components to give a long and reliable operating life in industrial applications such as presses, automation systems and wood working equipment.

The latest MW roundline series is available in two versions: the MWA, for working pressures up to 250 bar, and the MWB for pressures of up to 160 bar.

Depending on the version, standard stroke lengths range up to 4000mm, in a choice of bore sizes between 32mm and 200mm, with piston rod diameters from 14mm to 200mm.

In each case, the MW Series cylinders feature threaded head end rod bearings which accommodate a high performance polyurethane lipseal and wiper seal, while MWA cylinders are fitted with an additional PTFE seal with energiser.

All models feature welded end caps.

Both MWA and MWB ranges are available with a choice of five mounting options including flange, trunnion and pivot styles.

Each piston rod is manufactured from precision ground, high tensile carbon steel, hard chrome plated to a minimum thickness of 20 microns and polished, to ensure a long service life.

One-piece steel pistons are fitted with a durable elastomeric sealing element, supported by twin wear/anti-extrusion rings.

This robust construction ensures that each cylinder provides a long and reliable operating life with minimal maintenance requirements.

The standard MW Series hydraulic cylinders are designed for use with all conventional hydraulic fluids including water-based and 'green' fluids, and are able to withstand temperatures from -30 deg C to +80 deg C.

They can be customised to meet specific customer requirements; for example, spherical bearings at the rod and cap ends can be specified if an application requires a degree of tolerance when misalignment occurs when traversing a curved track.

Other options include integrated valve and manifolds, custom paint finishes, position switches, air bleeds, custom thread forms and lengths, as well as linear transducers.
