Adjustable upper and lower spans, roller-supported loading, multiple capacity options, and optional deformation measurement help laboratories perform standardized bending tests with stable support conditions and repeatable force application.

Wedge tensile grips are built for high-load tensile testing of flat and round specimens made from metals, composites, and plastics. Their wedge-action mechanism increases gripping pressure as tensile force rises, helping minimize slippage and maintain alignment during demanding tests. Available models support force capacities from lower-force laboratory work up to 300 kN, with interchangeable flat and vee jaw inserts for different specimen sizes.

Pneumatic grips provide fast, repeatable air-actuated clamping for universal testing machines in high-throughput tensile and compression workflows. Designed for wires, composites, polymers, films, fabrics, and other materials, they apply uniform gripping pressure while reducing operator fatigue and sample loading time. Side-action, wedge-action, and snubbing configurations, plus interchangeable jaw faces, support secure holding across varied specimen geometries and standards.

Shoulder fixtures are specialized tensile grips for specimens and components with shoulder geometries, where alignment and secure seating are essential for reliable pull-off or tensile testing. Compatible with NG-EML and SHM universal testing machines, they help laboratories reduce bending effects, improve repeatability, and support standardized ASTM and ISO workflows in research, production, and quality-control environments.

Compression fixtures provide aligned axial loading for rigid samples tested on NG-EML and SHM universal testing machines. They are suited for metals, polymers, elastomers, foams, composites, and construction materials where stable force distribution and specimen alignment are critical. High-rigidity construction, secure contact surfaces, and compatibility with ASTM D695, ISO 604, ASTM E9, and GB/T 14485 support repeatable compression testing.

These bending fixtures support standard 3-point flexural testing of plastics, composites, metals, ceramics, alloys, and construction materials. Designed for use with NG-EML and SHM universal testing machines, they offer adjustable spans, multiple capacity options, and repeatable roller-supported loading. Compatibility with ASTM D790, ISO 178, ISO 14125, ASTM E290, and GB/T 9341 helps laboratories perform consistent standards-based flexural evaluations.

Eccentric roller grips are built for low-force tensile testing of thin, soft, and flexible specimens such as rubber sheets, plastic film, and deformable materials. Their cam-driven roller mechanism increases clamping pressure as tensile load rises, helping prevent slippage without damaging delicate surfaces. Compatible with NextGen NG-EML and SHM systems, they support repeatable alignment and accurate testing of narrow specimens.

Self-tightening grips are designed for tensile testing of deformable, elastic, or low-friction materials such as rubber, plastics, foams, textiles, and biomedical specimens. As tensile force increases, the gripping mechanism automatically increases clamping pressure, helping compensate for thinning or elongation during the test. This reduces slippage, limits specimen damage, and improves repeatability without frequent manual adjustment.

Snubbing grips, also known as capstan grips, are designed for tensile testing of wires, cables, ropes, textile strips, and geogrids that can slip or break in standard clamps. By wrapping the specimen around curved surfaces, they increase friction and reduce grip-end failures. These fixtures help laboratories achieve safer, more repeatable axial loading for high-strength or flexible materials.

Side action tensile grips provide quick, secure clamping for films, thin sheets, textiles, fine wires, polymer strips, and other flexible specimens on universal testing machines. Available in manual lever and screw-action configurations, they support different force ranges, jaw surfaces, and specimen sizes. Their side-clamping design helps improve alignment, reduce slippage, and speed up routine tensile testing in QC and R&D labs.
