With multiple actuator position options and a second load train mounting position, this T-slot table test system can be configured for a wide variety of applications. Ideal for testing components and sub-assemblies.
T-slot table set at convenient working height for easy specimen placement
Two load train mounting positions place actuator and crosshead where you need them
Optional hydraulic locks to quickly unlock and lock the crosshead
Capable of testing small material specimen to large automotive subassemblies

¹ Determined at each Load Unit’s full fatigue rating with its crosshead raised 50 in (1270 mm) above the T-slot table. | ||||
Deflection rates can vary 20%, depending on the type of actuator and force transducer you use. |
| |||
For the most accurate high frequency test results, use a Load Unit with a fatigue rating that’s larger than its actuator’s force rating. (A 322.31 Load Unit with a 55 kip fatigue rating and a 22 kip actuator will be stiffer than a 322.21 Load Unit with a 22 kip fatigue rating and 22 kip actuator.) | ||||
