Pinching Grips Setup and Operation

Home / Testing Guides / Pinching Grips Setup and Operation

This post will help guide you through pinching (pincer) grip setup and operation on your universal testing machine. Pinching grips are low capacity tensile grips used to grip small size samples.

Pinching grips may be supplied as a manual version, pneumatic version, or with a chain mount for flexible positioning. For further information on ADMET pinching grip options, click here.

1. Installing the Grips

  1. Place female eye end of grip onto the male eye end on the testing machine.
  2. Align pin holes of male and female eye ends, insert pin.
  3. Using a spanner wrench, tighten locking nut against fixture to eliminate axial play (wobbling).

2. Grip Usage

  1. Place test specimen between pincers and tighten with thumb screw for GSP-0.1PT.
  2. Squeeze lever arms of GSP-CH-F to open the grip for specimen insertion.
  3. Insert specimen between the upper and lower grips to start testing.
