Boom Swivels

Boom swivels also known as ‘slewing rings’ or ‘rotating seals’ are used in many industries wherever a gear-operated rotating seal is needed. They are also the focal point of any boom operated vacuum system and are rated for extreme weight and high-stress operation. Our boom swivels are made in house and come in many different sizes and configurations to fit your tank and truck. They can be outfitted with a worm drive and hydraulic motor depending on your needs.

We offer 4” to 17” ring diameters in geared or non-geared options depending on your application, and 10” and 13” models  with or without a worm drive. All of our boom swivels include:

  • In-house laser hardened bearing courses for superior durability in high-stress conditions
  • High carbon steel rings
  • Chromed bearing balls
  • Custom made wiper seal for a perfect seal under vacuum
