HYDRAULIC SIDE ACTION TENSILE GRIPS
With a Patented Self-Centering Mechanical Synchronizer
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.
PATENTED DURASYNC TECHNOLOGY
SUPERIOR GRIPPING PERFORMANCE
Instron’s dual side-acting grips incorporate our latest DuraSync technology. This patented self-centering mechanical synchronizer 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 testing slightly bent or irregularly shaped specimens such as rebar or wire rod
- Opposing jaw faces repeatedly self-center during specimen clamping reducing testing time and eliminating the need to resynchronize the grip faces between tests
- The synchronizer is located outside the gripping pocket preventing mechanical failure due to contamination
Features
- Adjustable clamping force alleviates specimen slippage and grip breaks
- Operator safety is improved through the use of low-pressure (131 bar) external supply lines
- Hydraulic power is provided by the machine’s main power supply reducing the cost and floor space associated with a secondary grip pumping unit Note: For static electromechanical systems, a low-pressure, standalone pump is required.
- Fully open-front design provides easy specimen insertion increasing testing efficiency and safety
- DuraSync 2 offers semi-open back design which facilitates testing of shorter specimen when using an automatic extensometer
- Jaw faces are easily installed from the front side of grips and require no maintenance beyond simple cleaning
- Ergonomic control handset includes user-friendly, 3-position switches for upper and lower grip operation, and a magnetic back adding to operator convenience and productivity
- Grips are field-serviceable reducing down time and eliminating the cost of sending the grips back to the factory for service
Application Range
- Tensile tests on a wide range of materials including: steel rod and plate, machined rounds and flats, reinforcement bar, 3- and 7-wire strand, conveyor belt, and wood products
- Tension-tension cyclic tests
- Compression testing using optional secondary load string adapter
- Low-frequency, thru-zero cyclic testing with thru-zero support option
