Wear-resistant and quiet: xiros® two
component ball bearings

The two-component ball bearing is suitable for high-speed applications. The outer material provides stability, the wear-resistant inner material has a vibration-dampening effect.

The 3D-printed shell with undercuts ensures a high level of safety when the materials are connected. The blue material is extremely wear-resistant and responsible for the quiet operation.

Innovation - Why is it a novelty?
  • Combining the specifications of a soft and hard polymer to obtain a strong and quiet ball bearing at the same time

Effect - What goals were achieved?
  • The development of a world first - with two components customers cover several requirements than with only one component

Usability / user benefits - What benefits do customers derive from the novelty?
  • Higher axial load capacity compared to existing soft xiros materials
  • Particularly advantageous at high speeds
