| 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.) |
