Sp = clamp, Lo = unclamp
* Clamping force when using standard clamping lever

Design:

Cylinder housing from hardened steel, tempered. Top mounting with four cylinder screws (resistance min. 12.9), these are included in the supply scope. Pistons and bolts from from hardened steel, tempered, ground and nitrided. All parts nickel plated.
Supply scope includes hinge pins and tension plates, but not clamping levers. Oil supply via threaded port or oil channel in fixture body.

Application:

Link clamps are used in clamping fixtures in which workpieces must be freely accessible and loaded from above. Particularly suitable for clamping in clamping pockets.

Features:

Top flange version, lever mechanism can be turned in the range of 180º in 90º steps. Special designs are possible.

Note:

Maximum speed of operation 0.5 m/s.
Proximity switch and electrical pressure-point monitoring can be supplied on request.
