MORE THAN MANUFACTURERS
WE ARE YOUR ENGINEERING TEAM

We design, calculate, test and monitor.
All in-house. All with purpose.

An ecosystem of services for the entire life cycle

We don’t just deliver a bearing: we cover every stage in the life of your pitch and yaw bearings, from supply and replacement to high value-added engineering services.

Our goal is clear: to maximise the availability of your assets, prevent critical failures and reduce wind turbine downtime.

Bearing engineering services

Smart engineering that raises
your turbine's performance

Six services that answer the same question: how to make your bearings last longer and fail less.

Bearing root cause analysis (RCA)

01 Root cause analysis (RCA)

  • – On-site failure investigation at your facilities
  • – Independent metallurgical analysis
  • – Load assessment using operating data
  • – Report with proposed corrective actions
Bearing redesign

02Bearing redesign

  • – Comprehensive design: raceways, cages, seals, rolling elements
  • – Advanced fatigue and structural integrity calculation
  • – Proprietary ball and roller design tools
  • – Tailor-made proposals to prevent future failures
Laulagun bearing testing and validation

03 Testing and validation

  • – Product validation for OEMs
  • – Technology validation in R&D projects
  • – Assessment of design limits
  • – Our own test centre in Idiazabal
Turbine monitoring

04 Turbine monitoring (TPM)

  • – Condition monitoring tailored to each turbine
  • – Sensors and positions defined with you
  • – Adapted to the identified failure modes
  • – Anticipating any problem in operation
Bearing training and maintenance kit

05 Training and maintenance kit

  • – Training in correct seal replacement
  • – Prevention of lubrication-related failure modes
  • – Complete kit: tools + consumables + instructions
  • – Good practices to extend bearing life
Wind turbine with hub bearing

06 Field hub audits

  • – Hub inspection by expert technicians
  • – Detection of anomalies in moving components
  • – Verification of maintenance and lubrication
  • – Full report with recommended actions

And when it's time to replace, we're there too

Supply and replacement with fast response and minimal machine downtime.

Replacement bearings

Replacement of the bearing as an individual component, ensuring a fast response and minimum wind turbine downtime.

Replacement + peripheral kit

All-in-one kit for faster, safer installation: bearing, grease collection containers, torque or stiffening plate and lubrication system.

Validated on our test rigs

Six in-house test rigs in Idiazabal for testing complete bearings and their critical components: fatigue, extreme load, friction and sealing, monitored with dozens of sensors.
