High precision motors are used throughout industry to provide smooth and quiet rotation. From robotic exoskeletons to industrial actuation systems, high precision motors are increasingly in demand as a source of electrical power.

FIJ ball bearings provide the precision and performance this application demands. Low friction and noise levels, a lightweight and compact design, energy efficiency and a high life expectancy are all crucial requirements which can be met by the FIJ product range.

Product range

FIJ high precision motor bearings offer:

  • Optimised internal geometry and surface finish resulting in very low running friction and low noise and vibration properties.
  • Reliable performance, minimal maintenance requirements and longer life design.
  • Manufacture from a range of materials suitable for the application, including ceramic (silicon nitride) balls for increased wear resistance and resistance to electrical currents.
  • Designed to withstand heavy radial loads and moderate thrust loads in both directions.
  • High performance lubrication options and greased-for-life designs available.
  • Compatibility with high-temperature environments and high speed running.
  • Fully shielded and sealed versions of all bearings to prevent contamination ingress and contain lubrication.


Typical motor applications include:

  • Industrial automations and robotics
  • Industrial fans, blowers and pumps
  • Power tools and consumer products
  • Electric and hybrid vehicle applications
  • Aircraft and space vehicles
  • Medical and surgical equipment
