Eccentric Roller Grips for Thin and Flexible Samples

Description

Eccentric roller grips are self-tightening fixtures used for tensile testing of thin films, rubber sheets, flexible plastics, and other low-strength materials. The design uses an off-center roller that presses the specimen against a fixed surface. As the tensile load increases, the roller rotates and adds clamping force.

This mechanism maintains contact with the specimen as it elongates or reduces in thickness, helping prevent slipping or tearing during the test. To support delicate materials, the gripping surfaces are commonly coated with rubber or other non-marking materials.

Eccentric roller grips are used in research labs, quality control environments, and manufacturing lines that work with soft or flexible specimens. Their lever-operated design allows quick specimen setup while maintaining steady clamping throughout loading. These grips are compatible with ASTM and ISO test methods for films, elastomers, and similar materials.
