DescriptionItem
Allows axial-torsional grips to be mounted to a force transducer. The
adapter provides the thread needed to use the couplings.
• Adapter plate
Clamps the grips to the to the actuator and force transducer (via an
adapter). The couplings have left and right handed threads that
preloads the grip connection and prevents offsets in the force train.
• Upper and lower
couplings

Description
The Series 647 Hydraulic Wedge Grips are typically mounted in an MTS load unit to secure the specimen
under test. Hydraulic pressure to the grips is supplied by and adjusted at an external hydraulic grip supply.
The grips have a side loading design for quick and easy specimen installation.
