604533-00220/2 Single-row Outer-ringless Full-complement Cylindrical Roller Bearing
Selection Guide
Wind turbine gearbox bearings work under variable load and speed, frequent starts and stops, and a design life requirement of twenty years or more, so material cleanliness, heat treatment and raceway profiling requirements are far stricter than for general industrial bearings. When selecting or replacing, always verify dimensions (bore, outside diameter, width), the internal design code (cage type, roller profile modification), clearance class, and any special coating or surface treatment. Because capacity and life depend heavily on the specific gearbox design, we strongly recommend providing the gearbox model or the complete original bearing designation so we can carry out a technical check before quoting.

Yes—CAD/DXF/PDF high-precision drawings and 3.1 material certificates (GCr15 bearing steel) for 604533-00220/2 are available on request from RAYSDE.
604533-00220-2 Can I replace a wind turbine gearbox bearing directly by part number?
Yes, but only after a technical check. The same designation may have different internal designs across gearbox manufacturers — cage type, roller profile modification, clearance class and coatings can all differ, and identical external dimensions do not guarantee identical capacity and life characteristics. Please provide the gearbox manufacturer and model, the complete original bearing designation with suffixes, plus the failure mode and photographs. We will check dimensions and internal design, confirm interchangeability and quote, avoiding early failure after installation.
604533-00220-2 What are the common failure modes of wind turbine gearbox bearings?
Typical failures include fatigue spalling of raceways and rollers (often developing from micropitting), white etching cracks (WEC, associated with electrical current passage or lubricant chemistry), cage wear and fracture, and smearing or scuffing caused by poor lubrication. When investigating a failure, check the lubricant condition, filter elements and oil analysis results, and whether shaft currents are present — replacing the bearing without removing the root cause usually leads to a repeat failure within a short time. We can support failure analysis and improvement recommendations.
