Deep Groove vs. Angular Contact Bearings for Magnetic Bearing Motors

2026-10-06
Latest company news about Deep Groove vs. Angular Contact Bearings for Magnetic Bearing Motors

Magnetic bearing motors can use different types of mechanical bearings depending on the equipment design and operating conditions.

Two common bearing types are deep groove ball bearings and angular contact ball bearings.

Deep Groove Ball Bearings

Deep groove ball bearings are commonly used for radial load applications. Their compact design and ability to operate at relatively high speeds make them suitable for many precision motor applications.

Angular Contact Ball Bearings

Angular contact bearings are designed to accommodate radial and axial loads. They can be considered when axial load support, rigidity and running precision are important.

Which Bearing Should Be Used?

The selection depends on the complete application rather than bearing type alone.

Engineers may need to consider:

  • Rotational speed
  • Radial and axial loads
  • Required precision
  • Internal clearance
  • Preload
  • Shaft and housing design
  • Lubrication
  • Operating temperature

For specialized magnetic bearing motor applications, surface treatment can also be considered. Beining develops bearings with MoS₂ coating on the inner and outer rings for specific application requirements.

Beining Technology provides deep groove ball bearings, angular contact bearings and customized precision bearing solutions for high-speed motors, automation and other demanding applications.

Customers can provide drawings, dimensions, speed and load information for technical evaluation.
