MRI Scanners

Customer: Major MRI manufacturer
Application: Magnetic Resonance Imaging (MRI) Scanners


  • Must operate in strong magnetic field
  • 360-degree range of motion


Included in the design of a major MRI maker’s equipment was a table with a 360-degree range of motion. Because it operates in a very strong magnetic field, the table’s ball bearing had to be completely non-metallic.

Trelleborg Sealing Solutions proposed a custom Durobal®. Unique features of the design included low friction, self-lubrication and zero maintenance. The design allowed the table to move in/out and laterally on the machine’s bearing surface. MRI Scanner.

Extremely smooth movement provided added comfort and extra security to the patient during MRI procedures. As the bearing is composed entirely of thermoplastics and glass, problems with magnetic interference were eliminated.
