More information on our eccentric roller grip offerings can be found here.

1. Installing the Grips

  • 1.1. Place female eye end of grip onto male eye end.
  • 1.2. Align pin holes of male and female eye ends, insert pin.
  • 1.3. Using a spanner wrench, tighten locking nut against grip to eliminate axial play between grip and eye end.
  • 1.4. Repeat for second grip.

Setup for roller grip

Roller grip setup2. Grip Usage

  • 2.1. Open roller by lifting lever.  Center the sample in upper grip and release lever to engage.
  • 2.2. Zero (tare) load channel on indicator/controller, negating sample weight.
  • 2.3. Jog upper grip downward to allow sample to be fixed in lower grip.  Ensure centering of sample in both grips.
  • 2.4. Sample must align with vertical axis between load cell and lower eye end.  This alignment is to avoid additional torque and bending forces, which skew data.

3. Maintenance

  • 3.1. Clean grips after use. Wipe away sample fragments or residue.
  • 3.2. Grips do not require lubricant.
  • 3.3. If grip faces become worn or damaged, contact ADMET for a replacement set.
