Repair or Replacement of Damaged Components
Essential damaged components are repaired or replaced returning the unit back to operation.
New HSS & IMS Bearings
High speed shaft and intermediate shaft bearings repaired or replaced.
Bearings Upgrade
Up to date concept to eliminate known failures, such as bearing axial cracking and White Etching Crack appearance.
Micro Geometry Improvements
Gear teeth regrinding improvements provide a more accurate tooth connection and decrease the possibility of debris forming.
Elimination of Spinning Bearing Outer Races
Moventas service solution to completely stop the spinning of outer bearing races. The race spinning can cause bearing bore deformations leading to misalignment and ultimately to warping of the high speed and intermediate speed shafts as well as gearbox axels and housing.

Gearbox Expert Workshop Services
Extend gearbox lifetime with innovative, proven and
fit for purpose repairs. Alternatively, upgrade older
gearbox configurations to correspond with the latest
available technologies in the market. Benefit from
our experience in gearbox research and development,
material selection and manufacturing processes.
We understand, that the customer has irreplaceable
knowledge of the gearbox working conditions and
our service experts work with the customer to find
the root cause of the gearbox problem, and eliminate
any future instances of it. Moventas technical
capabilities and workshops will extend your gearbox
lifetime.

Case Carburized Ring Gear
Internal gearing case carburization offers the strongest resistance to wear. Gear lifetime can be doubled at planetary section, covering the entire gearbox design lifetime of 20 years, providing optimal running conditions for bearings.
All wind turbine gear manufactures recognize case carburized gears as superior. Moventas is the only wind gearbox manufacturer with the technological know-how to carburize inner gearings. Service brings this technology to you via ExtraLife.
Condition Management System, CMaS®
Moventas Condition Management System (CMaS) is a state-of-the-art service installed on thousands of units worldwide. Minimize downtime and costs while maximizing the lifetime of the wind turbine drivetrain. CMaS® is available for all workshop levels.
• See the real-time health condition of your drivetrain
• Installation onsite or in workshop• 24/7 global online accessibility
Clean Steel
Gear material upgrade to Moventas Clean Steel. Improved mechanical strength provides resistance against tooth fracture and flank breakage with increased gear surface safety of 10% and gear root safety of 5%.Tight Moventas material specifications prevent subsurface inclusions which act as initiation points for fatigue and tooth fractures.
Integrated Planet Wheel Bearings
Moventas Service is able to provide a larger WEC resistant and black oxidized bearing, in accordance with tight physical constraints.
This is possible with the incorporation of an outer raceway into the planet wheel. Resulting in a larger bearing with an even load distribution, better radial load handling, and greater planet gear stability. Flexspider technology allows planet pins to compensate for deformations. As an added benefit, there is no outer race that can spin inside the planet bearing.
