Advantages and benefits in application ■ Eminently suitable for highly stressed lubrication points ■ Highly effective due to dual lubrication effect ■ Economical due to possible reduction in frequency of lubrication ■ Saving of maintenance and lubricant costs by reducing downtimes and corrective maintenance due to wear During the process of joining segments that weigh several tons of the tower and the nacelle, the components, bolts, sockets and cones have to be joined smoothly. The MoS2 high-performance grease OKS 400 is a speciality lubricant that is used in particular at sliding surfaces subjected...

Lubrication of crown gears of the yaw drive Adhesive Lubricant OKS 495 is used as an adhesive lubricant in order to ensure lubrication of the tooth flanks of the yaw drive or also the pitch drives before the central lubricating system becomes active. OKS 495 is also used at the regularly planned maintenance intervals. OKS 495 is applied directly to the load-bearing tooth flanks. Intensive incorporation in the tooth flanks prevents the occurrence of air inclusions that negatively influence the establishment of an even lubricating film. A thin application is sufficient as corrosion protection for...

Advantages and benefits in application ■ Highly effective due to good adhesion to prepared substrates ■ Consistent coefficient of sliding friction under heavy loading of sliding film ■ Increased wear protection of sliding points that can otherwise not be lubricated One of the most important lubricating points of a wind energy plant is the yaw drive that is used to align the nacelle to the wind direction. The large slewing bearings implemented with a straight spur toothing nowadays do not have an additional drive crown gear. A toothing cut into the bearing rings simplifies the design and reduces...

BlOlogic Industrial Cleaner, water-based concentrate Advantages and benefits in application ■ Synergetic combination of active ingredients with temporary corrosion protection ■ Free of solvents, no harmful vapours ■ Good separation behaviour. Gentle to plastics, seals, rubber and sensitive metal surfaces ■ Registered under Number 129003 in Category A1 by the NSF The aerodynamic properties of the rotor blade are decisive for the performance and output of the wind energy plant. Soiling can result in turbulences and performance drops. Therefore the rotor blades are usually cleaned parallel to the...
