Non-Magnetic Bearings for MRI Systems

Non-magnetic bearings are essential components in modern MRI systems, where even the slightest magnetic interference can affect image quality and machine performance. These highly specialized bearings are designed to operate in strong magnetic fields while maintaining precision, durability, and absolute magnetic neutrality. We supply a complete range of non-magnetic bearing solutions suitable for all MRI applications and related medical technologies.

Why Non-Magnetic Bearings Are Essential in MRI Equipment

Magnetic Resonance Imaging requires a stable, interference-free environment. Standard steel bearings cannot be used inside MRI systems due to their magnetic properties, which can distort imaging and disrupt equipment functionality. Non-magnetic bearings eliminate these risks by using materials such as ceramics, plastics, titanium, or austenitic stainless steels.

• No magnetic interference
• High dimensional stability
• Low noise and vibration
• High resistance to corrosion and chemicals
• Suitable for cleanroom and sterile environments

Materials Used in Non-Magnetic Bearings

Non-magnetic bearings are available in several material configurations depending on performance requirements:

• Full ceramic bearings – Si3N4, ZrO2 for maximum magnetic neutrality and high-speed capability
• Titanium bearings – extremely strong, lightweight, non-magnetic
• Polymer and hybrid bearings – suitable for low-load or auxiliary MRI components
• Austenitic stainless steel bearings – non-magnetic grades for specific mechanical loads

Typical MRI Applications

Non-magnetic bearings are used in multiple areas of MRI systems, including:

• Patient table movement systems
• Gradient coil cooling systems
• RF coil positioning mechanisms
• Vacuum and cooling pumps
• Drive assemblies and rotating elements
