Clamping Elements

Rod clamping with maximum clamping force

Pneumatic Rod Clamping
Holding forces 1,400 N to 36,000 N
Holding torques 15 Nm to 720 Nm

Immediate clamping in case of loss of pneumatics: Suitable for rods with diameters of 20 mm to 40 mm, the clamping elements LOCKED PN absorb the forces axially and rotationally. With holding forces of up to 36,000 N, they reach or exceed the levels of hydraulic clamps. The system costs are however lower.

Alongside clamping in both directions of motion, the LOCKED-PN also surprises with its compact design. They need less installation space and enable short rod lengths. Many users appreciate the modular system. It allows several segments to be stacked so that the necessary clamping force can be attained for every application.

The areas of application for the ACE product family LOCKED PN are mechanical engineering and machine tools.

Application Examples

Clamping Elements - LOCKED PN
With the help of hydraulic presses, cut ceramic parts are manufactured during the week. So that the rods of the upper and lower stamping plate do not sag when the press is at a standstill over the weekend or during holidays and therefore have to...
Clamping Elements - LOCKED PN
ACE clamping elements are inserted, as a variable stop, during a joining process for the production of drilling tools. They meet the requirements for a precise positioning of the workpiece head and an adaptation of the length tolerance of up to 3...
Clamping Elements - LOCKED PN
When processing the cables, the head of the machine is driven up against the rear wall. Here, an ACE miniature shock absorber ensures reliable damping in the end position. Clamping elements with the designation LOCKED PN-product family support...
