210-2 Screw-in cylinder, with spring return single-acting, pmax. 400 bar
These screw-in cylinders are used as space-saving clamping cylinders and are characterized, among other things, by their compact design. Thanks to the internal stroke limiter, the cylinder can also be operated without a counter clamping surface.
Info
These screw-in cylinders are used as space-saving clamping cylinders and are characterized, among other things, by their compact design. Thanks to the internal stroke limiter, the cylinder can also be operated without a counter clamping surface. The use of the double wiper reduces dynamic leakage.
Installation instructions:
The screw-in cylinder operates hydraulically, single-acting. It is reset via an integrated spring. The pressure oil is supplied via drilled channels. The cylinder is sealed against the base of the screw-in bore by a sealing ring. Due to the plunger design, ventilation of the rod chamber is unnecessary.
Important notes:
The cylinder can be loaded up to the maximum clamping force in the relaxed and retracted state.
maximum clamping force. Protect the cylinders from direct exposure to aggressive cutting fluids and coolants. General operating conditions and other information can be found in the catalog on the "Recommendations & parameters" page.

Practical example
Multiple clamping device for series production of various workpieces.
The device is used in a rotary table. The clamping length is 600 mm.
It uses 48 screw-in cylinders with a piston diameter of 20 mm and a piston stroke of 15 mm (order number: EZY-EM-020-015) and a controlled rotary feed-through for single-acting clamping elements with 6 stations, including 2x loading/unloading, controlled simultaneously (order number: DRG-5-EW-06-002).
