Hydraulic Side-Acting Grips
DuraSync™
Instron® hydraulic side-acting grips provide an innovative
solution for high-capacity testing and deliver enhanced gripping
performance, usability, and operator safety over traditional grip
designs. These advanced grips maintain a constant clamping force
on the specimen that acts perpendicular to the direction of testing
and is independent of tensile loading.
DuraSync Technology
Instron’s dual side-acting grips incorporate our latest DuraSync
technology. This self-centering mechanical synchronizer
(patent pending) provides many improvements over hydraulic
or mechanical rack and pinion designs commonly found in the
marketplace.
• Side-load dampening reduces the risk of grip damage when
t testing slightly bent or irregularly shaped specimens such as
t rebar or wire rod
• Opposing jaw faces repeatedly self-center during specimen
t clamping reducing testing time and eliminating the need to
t resynchronize the grip faces between tests
• The synchronizer is located outside the gripping pocket
t preventing mechanical failure due to contamination
Features and Benefits
Optional Accessories
• Wire strand holders and inserts designed specifically for testing
t 3- and 7-wire strand
• Secondary load string adapter plates for attachment of
t compression accessories and/or secondary tensile load strings
• Thru-zero support and jaw faces add the ability to perform
t low-frequency cyclic tests

Application Range
• Tensile tests on a wide range of materials
t including: steel rod and plate, machined rounds
t and flats, reinforcement bar, 3- and 7-wire strand,
t conveyor belt, and wood products
• Tension-tension cyclic tests
• Compression testing using optional secondary
t load string adapter
• Low-frequency, thru-zero cyclic testing with
t thru-zero support option
Notes:
1. For static electromechanical systems, a low-pressure, standalone pump is required.
Accessories for Materials Testing
• Adjustable clamping force alleviates specimen slippage
t and grip breaks
• Operator safety is improved through the use of low-pressure
t (131 bar) external supply lines
• Hydraulic power is provided by the machine’s main power supply
t reducing the cost and floor space associated with a secondary
t grip pumping unit1
• Fully open-front design provides easy specimen insertion
t increasing testing efficiency and safety
• Jaw faces are easily installed from the front side of grips and
t require no maintenance beyond simple cleaning
• Ergonomic control handset includes user-friendly, 3-position
t switches for upper and lower grip operation, and a magnetic
t back adding to operator convenience and productivity
• Grips are field-serviceable reducing down time and eliminating
t the cost of sending the grips back to the factory for service
