Push-Pull Linear-Rotary Feedthroughs FLRM Series Push-Pull Linear-Rotary Feedthroughs, FLRM Series Description The FLRM series of linear-rotary feedthroughs are based on the FLM series push-pull linear feedthroughs. The FLRM mounts on a standard 2.75" O.D. flange. Other size flange mounts are available. The body length has been increased to provide greater spacing between the linear bearings, and the 1/2" O.D. rod replaced with a 1/2" O.D. tube. An FRM-133-25 rotary feedthrough is mounted on the axis of the 1/2" tube, providing rotary motion at the probe tip. Linear motion is push-pull against the pressure differential (12 lbs. maximum). This unit is an all position device with position locks on both feedthroughs. Strokes of up to 36" are feasible, dependent upon payload, orientation and acceptable deflection. All metal construction for bakeability.
