Design:

Cylinder body made of tempering steel, blued. Exchangeable jaws. Standard version with serrated and hardened jaw. Jaw exchangeable. Complete with two mounting bolts (ISO).

Application:

Purely a counter-hold when using a hydraulic or mechanical pull-down clamp. The workpiece is pulled down onto the machine table by the horizontal force that is applied.

Features:

The smooth clamping jaw moves always against the machine tool table surface, i.e. the stop position is always the same. Clamping on slotted table possible lengthwise and crosswise. No raising of the clamping jaw, because the clamping bolt is right behind the jaw. Suitable for incorporation in fixtures. New design of jaws connection with rubber buffer ensures sliding without any play.

Note:

The maximum pull-down stroke of the jaw must not exceed dimension G. The hole ØD can be used for additional support or positioning.
