Set screw, ball-shaped
No. 6940
double-acting,
max. working pressure 400 bar,
min. operating pressure 25 bar.
Cylinder housing from hardened steel, burnished. Piston tempered, ground, nitrided, and treated with a corrosion-resistant coating. Oil supply via oil channel in fixture body.
These threaded cylinders can be used in all types of clamping fixtures. Ideal for pressure bars for tolerance compensation in multiple-workpiece clamping fixtures, and for positioning, holding or ejecting, and clamping workpieces. Can be used extending or retracting.
The O-rings are smaller than the diameter of the screw-in thread. This reduces the risk of damage to the seal during the installation process.
Two-piece body makes it easier to change the piston-rod seal. Housing seals against the surface of the hole sleeve. For sizes 05 and 08, there is additional sealing between the housing head and the fixture body.
Small dimensions, can be installed closely spaced side-by-side. The cylinder must be screwed into the fixture body up to its flange.
Maximum speed of operation 0.5 m/s
Can be supplied on request for higher pressures and temperatures.
