Plain bearing vs. roller bearing: How plain bearings are successfully replacing roller bearings

In many applications, the question plain bearing vs. roller bearing goes in favor of plain bearings, due to their increase in performance. Our expertise, as one of the world's leading manufacturers of hydrodynamic plain bearings, enables us to use Miba plain bearing technology to your advantage, including in wind power and aviation.


Plain bearings vs. Roller bearings

These applications benefit from the upgrade in technology


  • Airplane turbines
  • Wind turbines
  • Gearboxes
  • Refiners
  • Gas and steam turbines


In addition to plain bearings very successfully replacing rolling bearings when developing new applications, for existing applications switching to plain bearing technology also delivers customer benefits.

Plain bearings as a key element in gearboxes for wind turbines

Since 2008, we have been working on bearing solutions for main gearboxes on wind turbines that are already in series production. During a detailed design process, we develop customer-specific and application-driven plain bearing solutions. Power density can be increased even further in future by integrating the bearing functionality into the component using a direct coating. The question of plain bearing vs. roller bearing does not arise here.


Why plain bearings are replacing roller bearings in wind turbines:

  • Compact construction: reduces space needed and weight
  • Increased power density
  • Higher load capacity and excellent impact resistance
  • Reduced noise during rotation
  • Comprehensive material portfolio and expertise
  • Easy installation and reduced maintenance required
