Collection: Eccentric Roller Tensile Grips

Eccentric roller tensile grips provide fast, self-locking specimen clamping for testing thin, flexible flat materials like plastic films, foils, and rubber membranes.

Featuring a spring-loaded, off-center cam roller, these grips automatically rotate and bite tighter against a fixed flat jaw face as tensile load increases. This self-tightening action prevents specimen slippage during high-elongation testing while enabling rapid, single-handed specimen loading to maximize throughput in high-volume quality control environments.

Ideal for testing polymers, adhesives, thin sheets, and flexible packaging, eccentric roller grips ensure reliable axial alignment and align with international standards such as ASTM D882, ASTM D3330, and ISO 527-3 across universal testing machines.
