FAQ

  • Q How do I choose a rotary union?

    A Proper selection of a rotary union solution requires details about your application's operating parameters including pressure, speed, media type(s), number of flow passages (channels), and connection size(s) / type(s). A good place to start your search is with our Standard Rotary Unions. If you are confident that a custom / modified solution is most likely required or need assistance in your selection, contact us to Get Started. Our experts are here for you.

  • Q Is there a quantity price break if I order multiple units?

    A To discuss quantity price breaks, contact a member of our Sales Support Team.

  • Q Do you offer replacement seals and/or bearings for rebuilding your rotary unions?

    A Yes, seal and bearing kits are available for our rotary union products for on-location rebuilding and repair. Contact us to Get Started

  • Q Which part of the rotary union stays stationary and which part rotates?

    A Functionally it makes no difference whether the shaft or the housing rotates. It is all dependent on how the assembly is mounted and installed on your machine or equipment.

  • Q Can an axial and/or radial load be placed on a rotary union?

    A In most cases, some degree of load can be placed on a rotary union, but please contact a member of our Sales Support Team to better understand your application needs.

  • Q Can I use more than one media type in a rotary union at the same time?

    A Yes, if all media types are suitable for that specific rotary union. However, if using air/gas and another fluid, Focus Machiery recommends using a rotary union with an extra passage (empty) between the two to avoid cross contamination. Please speak with a member of our Sales Support Team to discuss your application in detail.

  • Q ISO 9001 Certification

    A Our ISO 9001 certification ensures a systematic approach to quality assurance for you.
