Series 647 Hydraulic Wedge Grips
The Series 647 Hydraulic Wedge Grips are versatile, easy-to-load grips for a wide range of tensile and fatigue applications.
MTS Systems — 645,002, 645,005, 645,012, Grips are sold in pairs.
The Series 645 Fatigue-rated Pneumatic Wedge Grips provide the versatility and reliability you won’t find in other pneumatic grips. The symmetrical housing design ensures even specimen loading across the entire face of the wedge. Based on proven MTS designs, the lateral movement of the wedges won’t change the gripping position on the specimen when the grips are energized.
