Motion Feedthrough

Rotary Feedthrough

VFR series

  • Standard: VFR-S
  • Economy: VFR-E
  • Hi. Temp: VFR-HT
  • Precision: VFR-P
  • Heavy Duty: VFR-HD

Rotary FT has 5 design variations; each for a specific requirement. See below table. Housing are made of aluminum, except Hi Temp series which is all SST All rotary FT comes standard with a scale.

"Economy Series", which does not have a scale, is a lowest cost version. Torque of Heavy Duty series can be as high as 240 in-lb.
"Precision Series" is equipped with a precision micrometer
