Linear / Rotary Feedthroughs

Lightweight, versatile transfer arms for UHV applications.

  • Exceptional Control: Experience near force-free manipulation with precise control.
  • High-temperature Bakeout: These transfer arms are suitable for temperatures up to 200°C.
  • Versatile configurations: Available in standard strokes (100-500mm) with customization options up to 750mm.

  • What are Linear / Rotary Feedthroughs?

    This transfer arm manipulator is a compact and versatile manipulator solution for short to medium length applicaitons. Featuring magnetic couplings that drive the in-vacuum rod, it offers unmatched smoothness and reliability during UHV transfers. Ideal for transferring sample or mounting movable sample storages..

    Why Choose Ferrovac Motion Feedthrouhgs?

    Eco-Friendly and Cost-Effective: With a maintenance-free lifespan of up to 10 years and readily available spare parts, these transfer arms reduce environmental impact and long-term costs.

    Precision and Reliability: Engineered for ultra-high vacuum (UHV) systems, Ferrovac manipulators operate seamlessly in pressures ranging from 1E-11 to 1000 mbar.

    Versatile Functionality: Multiple configurations and accessoires make the Linear / Rotary Feedthrough adaptable for a wide range of applications far beyond transporting samples.

    Typical Applications

    Ferrovac Linear / Rotary Feedthroughs are available in various configurations to meet a wide range of applications, such as:

    • Sample Handling: Precise transportation of samples within the vacuum chamber.
    • Sample Parking: Creates compact and easy-to-use parking racks when combined with a stack of receptacles.
    • Heating Stage Carrier: Ideal to carry mobile sample heating stages
    • In-Vacuum Tools: Engage and disengage thermal links, activate screws, utilize scrapers, and much more.
    • And much more…

    Shaft:

    For most transfer applications, the single shaft option fulfills all requirements.
    They offer both rotational movement and linear extension/retraction, while maintaining a highly tactile feel and smooth operation.

    In certain cases a dual-shaft solution offers additional actuation for vacuum-side end effectors.

    Flange:

    Linear / Rotary Feedthroughs are available with mounting flanges in the standard sizes DN16CF and DN40CF.

    Retracted Length [mm]

    Specifies the minimal length of the shaft extending from the DN40CF flange surface towards the vacuum side, while the manipulator shaft is fully retracted.

    Linear Travel [mm]

    The maximum travel distance of the transfer shaft. Added to the retracted length, this defines the shaft's maximum extension into the vacuum chamber.

    Options:

    HT Option - For Heavy Load Applications: For applications that require increased force, the High Torque version delivers more power for tasks such as securely fastening sample holders in position, or engaging a mechanically activated thermal link. It ensures the reliable application of high torque without compromising precision

    (Y0) Option - Zero Retracted Length Option: Designed to make the most out of the space available in our UHV suitcase chambers, this version sports the shortest possible retracted shaft length on the vacuum side.

    (RL) Option - For Controlled Rotation Limits: In some applications where visibility is low, or in cases where very fragile components are handled, the limitless, continuous rotation capabilities of the coupling can be limited with an optional Rotation Limit component.
