Romheld - Model B1.4301 Series -Threaded-Body Cylinder

These clamping cylinders may be threaded directly into tapped holes of the fixture. These compact devices can be used to great advantage in fixtures where space is at a premium. Hydraulic fluid is supplied through passages drilled into the fixture body, thus eliminating hydraulic hoses and threaded fittings. The built-in spring returns the piston when hydraulic pressure is released.
