Rack & Pinion Linear-Rotary Feedthroughs RPLR Series


Rack & Pinion Linear-Rotary Feedthroughs, RPLR Series

Description


RPLR-.75/RRO (shown with optional /RRO remote rotary operation)

The RPLR series of linear-rotary feedthroughs uses a 3/4" diameter probe. The probe is actuated by a rack and pinion positive drive (rotary bellows sealed feedthrough). The independent rotary actuation is achieved by a second rotary feedthrough. Only the 3/8" diameter probe tip rotates, keyed with a ball bearing keyway. This allows mounting of jaw-type devices which are actuated by the rotary action. The standard mounting flange is a 2.75" O.D. rotatable flange. The RPLR is an all position device with position locks on both rotary feedthroughs. All metal construction for bakeability.

This unit is also available as a linear-only feedthrough (RPL Series).

Options

Option: Mechanical Counter Model Number: /MC Price: add Contact per axis
  • 40 counts per feedthrough rotation (approximately 0.034" linear travel per count on RPLR)
  • Removable for bakeout
  • Retrofit kit allows mounting without breaking vacuum

  • Motorization Options    
    /MS Stepping or /MY Synchronous Motorized Rotary Feedthrough
    Model Number: /MS (Stepping) or /MY (Synchronous)
    Price: add Contact per axis
    • With integral motor drive.
    • /MS stepping or /MY synchronous motor drive
    • 50 oz-in holding torque (higher torque motors available)
    • Low inertia design
    • Manual knob
    • Motor controller sold separately
    NOTE: The /MS or /MY motor option is suitable for the linear actuation when the operation is horizontal. When the linear travel is other than horizontal, the /MS/W option should be used.

    We strongly recommend the use of limit switches on this or any other motor drive being used to actuate the linear drive on the RPL or RPLR. The limit switch actuator assembly specified below (or one similar) should be used to protect the RPL or RPLR from being over-driven. See the RLS rotary limit switch option.


    /MS/W Stepping or /MY/W Synchronous Motorization with High Precision Worm Drive
    Model Number: /MS/W (Stepping) or /MY/W (Synchronous)
    Price: add Contact
    • Anti-backlash worm gear drive
    • Self-locking
    • Manual knob
    • Capable of driving up to 16"/min minimum at 1,000 pps
    • May be field-mounted without breaking vacuum, or returned to the factory for installation
    • Motor controller sold separately
    NOTE: This motor drive is self-locking. This is necessary to protect the probe and associated equipment from spinning down if the power is removed from the motor. However, because of the self-locking design, the drive can generate significant torque at the FRM, and thus do damage if overdriven.
