Series GRM1 miniature workholding clamp

The GRM1 miniature clamps are designed for applications requiring a compact size, light weight, and high clamping force. These clamps generate a total clamping force up to 1,000 N and are particularly suitable for robotics, end effector systems, and general industrial automation. The clamps are compact and lightweight, yet offer the highest clamping force in the industry for their size. Weighing 0.24 kg (without tips), they deliver a total clamping force of 600 N. They are available in two jaw types, the “S” Standard and the “F” Flange, for flexibility in use. The size 0 clamp has the same design as the larger GRM clamps, ensuring the same superior performance.

Advantages

  • Compact and lightweight (400 g) with high clamping force (1,000 N)
  • Secure clamping due to locking in closed position in case of pressure loss
  • Flexible jaw configurations (0°–50°) for diverse applications
  • Fast cycle time (0.2 s at 6 bar) for efficient production processes
  • Durable design with long service life and easy maintenance
  • Wide range of jaw tips for different material thicknesses and surfaces
  • Switch options and special seals for added functionality
