Dual Side Action and Wedge Hydraulic Grips for High-Capacity Tensile Testing

NextGen Hydraulic tensile grip - Dual side action - NG206DPS.01

NextGen’s Dual Side Action and Wedge Hydraulic Grips are engineered for high-load, high-precision tensile testing using universal testing machines (UTMs). These grips are suited to laboratories and manufacturers conducting rigorous tests in compliance with ASTM, ISO, DIN, JIS, and GB/T standards. Their heavy-duty hydraulic design ensures uniform gripping pressure, preventing specimen slippage and deformation, especially under elevated forces. Applicable for metals, plastics, and composite materials, these grips support automated test cycles, enhancing safety and repeatability in industrial or research environments. 

Compatible with all NextGen's UTM platforms, these grips are built for performance across tensile, compression, shear, and cyclic testing operations. 


Hydraulic Grip Models

Eight grips split by how the jaws are driven. The first five close from both sides at once, so the specimen stays on the load axis instead of being pushed off it. Each comes with its own jaw faces and its own hydraulic power unit. The range opens at 100 kN.

Model NGA105B

GenMark 500 – Automatic Gauge Length Marking Machine

The GenMark 500 is a full-automatic gauge length marking machine for metal bar, rebar and wire rod, applying the reference marks used to determine elongation after fracture. A servo-driven lead screw sets 5 mm or 10 mm spacing and a pneumatic tungsten steel needle marks specimens up to 500 mm gauge length, supporting ISO 6892-1 and ASTM E8/E8M workflows. Adjustable marking force, quick needle changes, and fixtures for both round and flat samples keep specimen preparation consistent across operators and shifts.
