Eccentric Roller Grip

The Eccentric Roller Grip is a general-purpose grip for flat samples. These eccentric roller grips are self-tightening grips primarily designed for the precision testing of elastomeric and other flexible materials exhibiting a large reduction in cross-section area under load. The sample is held between the body and the eccentrically mounted roller as the load increases the gripping action becomes self-tightening due to cam action between the roller and the body.

This eccentric roller grip has a cross-hatched, serrated finish and clamps tightly against a horizontal back plain. The upper grip is counter balanced so that the specimen can be aligned with the load cell to eliminate non-axial forces. They provide excellent testing accuracy, positive non-slip gripping action and are quick and simple-to-use.
There are two models of Roller grips and depending on the type, samples of 25 - 50 mm wide and 5-6mm thick can be accommodated. Thicker samples will fit but the load axis moves to far from the centre of the mounting hole, also the self-tightening action becomes less effective with thicker samples. Electro-less Nickel plated surface finish are used throughout to provide excellent corrosion and scratch protection.
