Parker Hannifin has released a new catalogue detailing the features and specifications of its 2H series hydraulic cylinders. The heavy-duty cylinders incorporate a number of features such as tie rod construction enabling them to offer outstandingly long and efficient service life under high working pressures. Parker hydraulic cylinders offer a compact and cost-effective method of moving, positioning or clamping tools or work-pieces in a variety of industrial applications, ranging from automation and machine tool systems, to presses, injection moulding and die casting machines.

The heavy-duty 2H series incorporates a number of innovative features, designed to improve overall performance and reliability, while extending operating life.

The cylinders' piston rods are manufactured from precision ground, high tensile carbon alloy steel, hard chrome plated and polished, to eliminate the problems caused by impact damage, scratches and abrasions which result in shortened gland seal life.

Similarly, the steel cylinder body tube is surface finished to minimise internal friction and wear, prolonging the life of piston seals.

The cylinders feature pressure-energised body seals to ensure that leakage is prevented even under pressure shock conditions.

As well as lip seals manufactured from an enhanced polyurethane, with a life of up to five times that of traditional materials, the piston rods also feature a double lip wiper seal that prevents the ingress of dirt into the cylinder and as a result extends the life of gland and seals.

2H tie rod cylinders are available in a range of bore sizes and stroke lengths, and are able to withstand working pressures of up to 210 bar.

Optional features include end of stroke cushioning for controlled piston deceleration, bespoke rod and port sizes, stroke limiters for use where absolute precision in stroke length is required, and rod locking devices providing fail-safe operation.

The new 2H series catalogue is now available, detailing these features in depth and listing the properties (including dimensions, and mass and nominal force) of the entire product range.

Sections are included on cushioning, pressure limitations and ports, and seals and fluids, making the catalogue a useful reference guide, while a how to order section makes product selection refreshingly simple.
