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

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

general

Power clamping screws
- mechanical
- hydromechanical
JAKOB clamping screws were conceived right from the beginning for highest demands and maximum workpiece weights with best possible operational reliability. 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

Hydro-mechanical spring clamping cylinders
The piston assembly (pulling or pushing version) is subjected alternatively to the cup spring force or hydraulic pressure. This means that the cup spring packet is compressed more with increasing pressure. The hydraulic pressure is required only for the release stroke of the elements whereby the pull stud/pressure piece is released. This System ensures a very high factor of safety since the clamping force generated is independent from the oil pressure and from pressure loss due to leakage.

Characteristics
• mechanical clamping-hydraulic releasing
• high operation safety
• leakproof and robust
• economical clamping solution

Hydromechanical power clamping nuts - hydraulic nuts
JAKOB- Hydromechanical power clamping nuts of series HM are designed for maximum clamping forces as soon as for highest demands conserning reliability, operating comfort and product quality.

Special characteristics:
• highest clamping forces - large operating path
• simple manual operation with clamping force control
• maximum reliability with counter ring
• no torsional and lateral forces by clamping
• compensation of unevenness through flexible surface
• spring reurn of hubs, leak proof oil refeed
