Special Lubricants for Wind Power Applications Made by Fuchs Lubritech and Fuchs Europe in a Powerful Partnership – The Fuchs Wind Power Division
a report by Dirk Kempkes1 and Hanno Paul2 1. Business Development Manager Wind Power, Fuchs Europe Schmierstoffe; 2. Product Manager, Pastes and Grease Pastes, Fuchs Lubritech
Today’s most demanding applications for lubricants can be found in wind power plants. Gearboxes, main bearings, pitch and yaw bearings with the drives and toothing systems, hydraulic systems and generators are expensive machine elements or parts. It is costly and highly problematic to change these components after they have been installed in the nacelle on top of the turbine. To avoid malfunctions and premature breakdowns of wind power plants, the Fuchs Wind Power Division offers a complete range of special lubricants – greases made by Fuchs Lubritech and fluids made by Fuchs Europe. These are especially developed and precisely balanced to protect all of the mechanical components of today’s wind power plants.
Different participants in the world of wind power have different requirements in terms of the performance of lubricants. Manufacturers of wind turbines and related parts want to have lubricants with the best performance and longest lifetime. Long-term guarantees often can be decisive in this business.
Greases
In addition to the requirements of the manufacturers, wind power plant operators often like to have ‘multipurpose greases’ that have a high performance but are easy to handle. Their main focus on avoiding too many different lubricants is to prevent possible ‘mix-ups’ of the different greases for bearings and toothing systems, for example. They like a ‘one-for-all’ grease, even if it is not easy to create in practice.
STABYL EOS E 2
Fuch Lubritech, as a specialised manufacturer of greases for wind power applications, therefore offers the high-performance STABYL EOS E 2 grease to be used in main, pitch and yaw bearings and also for the toothing systems of large machine elements. Such highly stressed bearings have to tolerate permanent vibrations and constantly changing torques, with additional influences, such as different temperatures and changing humidity.
Dirk Kempkes is the Business Development Manager Wind Power for the Fuchs Wind Power Division. He is responsible, in coordination with the product management department, for the gear and hydraulic oil business. He is a member of the International Organization for Standardization/International Electrotechnical Commission (ISO-IEC) Joint Working Group for the new international gearbox standards for wind power applications and a member of the German VDMA/FVA Research Group. After academic study of mechanical engineering and process engineering he worked for several companies in the industry between 1983 and 1988.

Hanno Paul has been the Product Manager for Pastes and Grease Pastes, Fuchs Lubritech since 2006. Hanno has studied design engineering, environmental protection technology and plant design engineering. He has had ten years practice in maintenance. And five years practice in application engineering for lubrication.
The technical details of gleitmo 585 K include: •
• 62 gleitmo 585 K
This is a fully synthetic special lubricant containing a synergistic combination of white solid lubricants. With gleitmo 585 K being the flagship and top product in the wind power business, Fuchs Lubritech offers this high-performance speciality grease with outstanding wear and corrosion protection for pitch and yaw bearings as well as for toothings (lube pinions are required).
gleitmo 585 K’s combination of white solid lubricants offers excellent protection against wear, especially under critical operation conditions, such as vibrations and oscillation movements under high load, which are typical for pitch and yaw bearings on wind turbines. gleitmo 585 K is well-known in the wind power industry. It has been used as an original equipment manufacturer (OEM) first fill and service lubricant for many years with good results.
STABYL EOS E 2 is based on a fully synthetic ester and contains lithium soap as a thickener. It fulfils the highest technical requirements for modern lubricants used in wind turbines. It was developed in a perennial research project in cooperation with leading bearing manufacturers and is successfully in use on wind turbines as a general- purpose lubricant. It is also used for the toothing system of the yaw and pitch bearings (lube pinions are required).
The technical details of STABYL EOS E 2 include: •
•
universal application on wind power units, especially for pitch, yaw and main bearings;
extremely wide temperature range, suitable for all climatic conditions from -40 to ≤130ºC;
• has National Lubricating Grease Institute (NLGI) grade 2 consistancy; •
the classification KPE 2 K-40 according to DIN 51502 (German Standard);
• • • • •
considerable reduction of lubricant diversity on wind turbine units; good protection against false brinelling and fretting corrosion; high load-carrying capacity at low rotational speeds; pumpable in automatic lube systems; and
Specially approved by Rothe Erde (ThyssenKrupp) this incorporates IMO and ZS lubrication systems.
It is currently used by lots of wind power plant manufacturers such as, users of wind power plants and parts.
outstanding wear protection, especially at shock loads and oscillatory movements for use in pitch and yaw bearings; suitable for all climatic conditions;
