Precision Open-Axis Rotary Feedthroughs, WOA Series
Description
WOA-550/FA/W (shown with optional /FA/W fine adjust worm drive)
The WOA rotary feedthrough is an all
metal-sealed rotary feedthrough with unique features and exceptional performance.
Open Axis
The WOA feedthrough has a 3/4" rotary tube with a clear
axis diameter of 0.55". The top of the rotary tube
has a fixed 1.33" O.D. flange (2.75" O.D. optional).
This open axis feature allows a multi-axis feedthrough to be constructed
by stacking multiple linear or rotary feedthroughs onto the WOA
feedthrough. A variety of coaxial rotary and/or linear
drives can be produced.
Precision
The WOA feedthrough demonstrates unique rotary precision. Tests confirm resolution of better than 0.003° with a backlash of less than 0.005° for positioning (no torque load) applications.
Readability
Standard scale: 1° graduations
/FA with vernier: 1 minute
