Self-Tightening Grips for Deformable and Elastic Materials

Self-Tightening Grips for Tensile Testing

NextGen’s self-tightening grips are engineered for precise tensile testing of deformable and elastic materials such as elastomers, foams, thin plastics, textiles, and biomedical specimens. These grips automatically increase clamping pressure as tensile force is applied, adapting to changes in specimen thickness without manual adjustment. Ideal for soft or low-friction materials that are prone to slippage or damage, the grips come in popular designs like scissor grips, cam-action grips, and lever-actuated jaws—all optimized for compatibility with NextGen’s Universal Testing Machines. By maintaining reliable alignment and consistent gripping force throughout the loading cycle, they ensure accurate, repeatable results in both quality control and research environments.

NGA203A – Self-Tightening Tensile Grip

The NGA203A Self-Tightening Grip is specifically designed for tensile testing of deformable and low-strength materials such as plastics and rubber. Its self-tightening mechanism ensures that clamping force increases automatically as tensile load is applied, making it ideal for specimens that thin or elongate during testing. This grip reduces slippage and avoids specimen damage without requiring manual adjustments. It is compatible with standard universal testing machines and provides stable performance in ambient laboratory conditions.

• Application: Tension tests for soft plastic and rubber materials.
• Maximum Capacity: Up to 2 kN load.
• Connection: Ø10 mm pin mount (upper and lower), suitable for standard UTM interfaces.
• Dimensions: Height 75 mm; Grip body width 104 mm for secure and compact clamping.
• Specimen Range: Accommodates specimens up to 10 mm in thickness and 30 mm in width.
• Grip Weight: Approximately 0.49 kg each for upper and lower grip.
• Working Temperature: Ambient laboratory environment.

NG5203A – Self-Tightening Tensile Grip

The NG5203A Self-Tightening Grip is built for tensile testing of flexible, low-friction materials such as plastics and rubber. With a higher load capacity and wider specimen accommodation than lighter models, it is ideal for materials that stretch or deform under stress. Its self-tightening mechanism ensures progressive clamping force as the tensile load increases, minimizing slippage and preserving specimen integrity. Compatible with standard UTMs, the grip delivers consistent results in ambient laboratory environments.

• Application: Tension tests for plastic and rubber materials.
• Maximum Capacity: Up to 5 kN load.
• Connection: Ø10 mm pin mount (upper and lower), compatible with standard UTM systems.
• Dimensions: Height 137 mm; Grip body width 150 mm, offering a stable clamping surface.
• Specimen Range: Suitable for specimens up to 12 mm thick and 45 mm wide.
• Grip Weight: Approximately 1.5 kg each for upper and lower grip.
• Working Temperature: Ambient conditions.
