Non Magnetic Bearings for MRI Equipment

Bearings for Medical Applications & Devices

A plastic race radial ball bearing fitted with borosilicate glass balls is the only type of ball bearing used in MRI patient tables. Its nonmetallic nature is required because the imaging area must remain nonmagnetic, or metal-free. 

Critical Design Features: POM, PBT, or UHMW-PE plastic races and cage fitted with borosilicate balls for total nonmetallic construction. True Race Technology™ ball grooves reduce friction and improve performance. UHMW-PE  or Polyurethane can be used as the outer race wheel to reduce noise and be non marking when the bearing wheel runs on a hard track surface.

Additional reasons for use:

  • No lube required: The ability to run without lubrication is a benefit when cleanliness is a priority.
  • Integration & assemblies: KMS can design a custom housing to provide a complete assembly. Spherical profiles can be designed on the outer race of the bearing to create an “all in one” bearing wheel.

Plastic Vs Steel

Lightweight: Plastic is five times lighter than steel, thereby reducing the weight and energy to move them.
