The friction-free bearing design used in the ELectroForce Series Instruments utilizes a flexure assembly. A flexure is a metal strip that allows travel perpendicular to it's length. The design used in the ELectroForce is unique in that it provides both long travel and high lateral stiffness. Since there are no sliding surfaces with this approach, there is no friction or debris generation to shorten the life of the motor. The bearing life has been demonstrated in the 11 BB cycle tests.
Any measurement system can have errors due to vibration or scan rate.

A common misconception about our machines is that they run only at frequencies greater than 60 Hz. In fact, our machines perform excellently from zero to 60 Hz as well as from 60 to 100 Hz. Data from these tests have been used for successful FDA submittals. We have installations running as many as four servohydraulic systems from the same computer.
