Port Aligners

Enables the distance and angular relationship between two flanges to be adjusted, where a fixed flange supports three equi-spaced threaded shafts, and in parallel, a travelling flange has adjustable floating mounts. A typical application would be the final alignment of sample transfer arms.

Features

  • Any-orientation mounting
  • +/- 5mm axial adjustment
  • +/- 3° angular tilt
  • High quality flexible 316L bellows accommodates motion, whilst maintaining ultra-high vacuum
  • Bakeable to 250°C

The Port Aligner range enables the distance and angular relationship between two flanges to be adjusted. The range consists of five series, which can be supplied with either tapped or clear bolt holes on the flanges. Each range provides +/-5 mm axial length adjustment, with +/- 3° angular tilt.

Essentially, this is a simple device that once adjusted, provides a stable platform. The design consists of two approximately parallel flanges, one of which remains fixed, whilst the position of the second may be adjusted with respect to the first.

The fixed flange supports three equi-spaced threaded shafts. Alignment of the travelling flange is achieved by adjusting the floating mounts attached to each threaded shaft. The port aligner can be mounted in any-orientation and is bakeable to 250°C.

A high quality, flexible, 316L edge-welded bellows, spans the flanges to accommodate the required motion while ensuring an all-metal vacuum enclosure.
