Efficient manufacturing of parts in the metal-cutting and metal-forming industry without quick clamping elements is inconceivable nowadays. JAKOB clamping elements meet these requirements perfectly due to their various force amplifying systems. They are a true alternative to conventional clamping elements as well as expensive half or fully automatic clamping systems.

Characteristics:
• high clamping forces
• high operational safety
• simple manual operation
• compact and flexible design

• Mechanical

• Hydromechanical

JAKOB clamping screws were conceived for highest demands and maximum workpiece weights with best possible operational reliability in mind right from the start. The user can choose between single- and double-acting designs. The screws are equally suitable for external and internal clamping. JAKOB clamping screws are used in faceplates or clamping discs on vertical-, horizontal-, center-, facing- and roll turning lathe, in grinding- and special-machines.

Characteristics:
• enormous clamping force
• maximal reliability, high rigidity
• large clamping stroke
• simple manual operation

The piston assembly (pulling or pushing version) is exposed to the interaction of cup spring force and hydraulic pressure.The clamping force is exerted by a pre-stressed spring cup.The hydraulic pressure is only required for the release stroke of the elements by which the pull stud/pressure piece is released. This system ensures a very high factor of safety since the clamping force generated is independent from oil pressure and unaffected by leakage.

Characteristics:
• mechanical clamping-hydraulical release
• high operational safety
• leakproof and robust
• economical clamping solution

The holding force of a clamping device during mechanical tooling is of special importance. It is relevant for tooling quality, but also for the safety of the operator, the workpiece and the machine tool.
