  • Dual Shaft, Dual Rotary Transporter: Available Translation Mechanisms

    RMJ40 - Standard Slide Translation (Recommended):

    • A specially designed inner sliding ring with minimized contact points ensures smooth and precise movement of the inner rods through the shaft, enabling effortless sample transfer. This highly durable design is ideal for ultra-high vacuum (UHV) environments and is our recommended version.

    RMD40 - Dry Lubricated Ball Bearing Translation:

    • This version utilizes sapphire hybrid ball bearings with a Dicronite (WS2) dry lubricant coating to ensure smooth and precise rod translation within the shaft. It is recommended exclusively for ultra-high vacuum (UHV) applications where minimal outgassing is paramount.

    Both the RMJ40 (Recommended) and RMD40 are available in standard lengths or can be customized to your specifications.

  • This heavy-duty sample transporter is a robust, all-metal transfer rod designed to move samples between ultra-high vacuum (UHV) chambers.

    • Enhanced Stability: Its square, tubular shaft provides superior stability compared to traditional solid shafts, making it perfect for:
      • Longer models (>500mm)
      • Heavier loads
    • Independent Rotation: The inner shaft rotates independently, allowing for precise sample manipulation with tools like pincers or rotatable sample carriers.Note: This model features a single rotary design, allowing for independent rotation of the inner shaft but not rotation of the end-effector itself.
    • Smooth Motion: The square shaft glides smoothly within slide bearings, while the inner shaft rotates precisely on sapphire hybrid ball bearings, ensuring accurate and reliable sample transfer.
    • Strong Coupling: Rare-earth magnets ensure a secure connection between the handle and the shaft.

    Shaft Orientation:
    The standard shaft orientation is shown in the image. However, you can specify a 30° rotated orientation (H option) if needed. This is important when using a PGRMS pincer, as the flange bolt hole orientation determines whether the pincer jaws open horizontally or vertically.

    Manipulator Motions:

    • Linear travel
    • Inner rod rotation
