MINIRAIL - the range of high-precision guideways

MINI-X Impressions

MlNlRAlL represents the latest generation of miniature guideways for sophisticated applications.

They are extremely robust. Their smooth running precision and reliability are demonstrated in every application. The design, material selection and surface finish of the recirculation element and ball entry zone, guarantee low pulsation and therefore a smooth ride. The range includes eight rail widths which can be combined with up to four carriage sizes.

NEW: short carriage version (Order code MNNS). The best choice for restricted installation spaces.

Customer benefits of the short carriage:

  • The compact, short carriage is ideally suited to small installation spaces
  • Consistently high level of accuracy
  • Long lifetime
