4.1.1.1 Roller Screw Vs Hydraulic & Pneumatic Comparisons:
In applications where high loads are anticipated or faster cycling is desired, roller screw actuators provide
an attractive alternative to the hydraulic or pneumatic options. With their vastly simplified controls,
electromechanical units using roller screws have major advantages. They do not require a complex support system
of valves, pumps, filters and sensors. Thus, Exlar units take up much less space and deliver extremely long
working lives with virtually no maintenance. Hydraulic fluid leaks are non-existent. Noise levels are reduced
significantly. Additionally, the flexibility of computer programmed positioning can be very desirable in many
applications.
