Welker Pin Clamps

Welker Pin Clamps offer positive part location and clamping. With the dual finger design, clamping is achieved on both sides of a hole or slot. Maximizes work access to part.

  • The unique gapless finger design keeps contaminants away from the internal mechanism.
  • Linear clamping ensures positive clamping for multiple parts, flanged holes and part thicknesses within a 7mm range.
  • World switch compatible.
  • Applications: underbody fixtures, end effectors - replaces separate pin and clamp. Ideal for geometry setting or material handling.
  • All Welker Pin Clamps are NAAMS compatible
The only pin clamp on the market with a replaceable cartridge for cost savings!
