Clamps

Mechanical and hydro-mechanical clamping elements from GAM/JAKOB with various force amplification systems meet the increased demands for shorter set-up and production times. They present an alternative to simple, mechanical clamping devices (clamps, brackets...), as well as to half and fully automatic clamping systems with complex energy supply and control. Either as original equipment or retro-fit GAM/JAKOB power clamping elements keep your tools and work pieces in position safely!

 

Mechanical Power Clamping Screws


 

 

  • Wedge clamping system with force amplification
  • High clamping forces at low tightening moments
  • Maximum operational safety – self-retaining mechanism
  • Easy, manual operation
  • Clamping forces of up to 250 kN

Mechanical and Hydro-mechanical Power Clamping Spindles


 

 

  • For mounting in face plates, as in jaws of lathe, grinding and special machines.
  • Very high clamping forces at low tightening moments
  • Maximum operational safety and stiffness
  • High force clamping stroke and high alignment precision
  • Easy operation and mounting, minimum maintenance
  • Clamping forces of up to 750 kN
 

Mechanical Power Clamping Nuts



 

  • Easy, manual operation - low tightening moments
  • Maximum clamping forces through force amplification
  • High operational safety through self-retention
  • Corrosion-protection and robust up to 400°C
  • Design with blind hole or through threads
  • Clamping forces of up to 200 kN

Hydro-mechanical Spring Clamping Systems



 

  • Two types as spring tension / spring pressure cylinders
  • Mechanical clamping – hydraulical declamping
  • Maximum operational safety – leakage-proof and robust
  • Clamping force is mechanically applied through a preloaded cup spring package
  • Temperature range: -30°C to +100°C
  • Clamping forces of up to 350 kN
 

Hydro-mechanical Spring Clamping Systems



 

  • Highest clamping forces, high clamping strokes
  • Maximum operational safety with counter ring
  • No torsional and transversal forces during clamping
  • Compact – robust – corrosion protected
  • Spring-retraction of forcers - leakage-free oil feedback
  • Compensation of flatness faults through floating surface
  • Clamping forces of up to 3,250 kN
