Description

The Instron® 8874 is a compact tabletop biaxial servohydraulic testing system that meets the challenging demands of various static and dynamic tests. The system carries out axial, torsion, or combined axial-torsion tests. With the actuator in the upper crosshead and a lower t-slot table, the 8874 makes an ideal platform for testing a variety of medical devices, biomaterials, advanced materials, and other components testing. • Double-acting servohydraulic actuator with force capacity up to ±25 kN (±5620 lbf) and torque capacity of ±100 Nm (880 in-lb) • High-stiffness, precision-aligned load frame with twin columns and actuator in upper crosshead • 100 mm (4 in) of usable axial stroke and ±130° of rotation • Designed for both dynamic and static testing on a variety of materials and components • Choice of hydraulic confi guration and dynamic performance to suit application • Adjustable upper crosshead with hydraulic lifts and manual locks fi tted as standard for easy adjustment of daylight • Patented1 Dynacell™ load cell technology for faster testing and reduction of inertial errors • Compact tabletop servohydraulic fatigue testing system –frame requires less than 0.4 m² (4.3 ft²) of space • Designed to be used with the 3520 Series of Hydraulic Power Units • Compatible with a large range of grips, fi xtures, chambers, video extensometers, protective shields, and other accessories • Patented stiffness based tuning algorithm that enables users to tune a variety of specimens in seconds
