Parker Hannifin hydraulic tie rod cylinders incorporate a number of innovative features, designed to improve overall performance and reliability, while extending operating life.
For example, 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.
In addition, the polyurethane gland seals are paired with heavy duty wiper seals, to prevent the ingress of contamination.
Housed in a detachable gland bearing, these seals can generally be inspected and replaced without dismounting the cylinder, while pressure-energised body seals ensure that each cylinder remains leak-tight even in applications that are subject to high levels of pressure shock.
Standard Parker hydraulic tie rod cylinders are available in a range of bore sizes and stroke lengths, and are typically rated to 210 bar which, size for size, is up to 30% higher than competing products.
Depending on the product, options can include different rod and port sizes, piston and seal combinations to match varying duty cycles, end-of-stroke cushioning for controlled piston deceleration, and integrated analogue or digital position sensors. Request a free brochure from Parker Hannifin ...
