Hollow piston cylinders, with internal piston thread

Hollow piston cylinders are used in combination with mechanical clamping elements in hydraulic clamping fixtures as traction and thrust cylinders. The piston has a threaded through-bore which can, for example, be used to screw in the tensile rods. The integrated metal wiper prevents the piston from being damaged by metal shavings, thus increasing the availability and service life of the cylinders. The external thread of the housing allows versatile installation options, including using lock nuts. HYDROKOMP offers single-acting (with reset spring) and double-acting hollow piston cylinders. For the purpose of supplying oil, the hollow piston cylinders are equipped with G1/4 threaded ports.

• suitable as traction or thrust cylinder

• pistons with through-bore

• use of tensile rods possible

• various installation options

• protection against shavings via integrated metal wiper

• standard cylinders and special designs available

Operating conditions:

For single-acting hollow piston cylinders, the penetration of foreign objects and liquids into the spring cavity must be prevented via preventive cylinder arrangement or by covering. If required, a vent line can also be connected. In order to prevent the threading from becoming damaged during use, the grooved nuts must always be tightened according to the load. The user must ensure that the tensile rods and screws are made of a material with a strength class of at least 10.9. This is especially applicable for maximal operating pressures between 350 and 500 bar.
