Main Bearing Grease
Main bearings use the most grease in the wind turbine. The bearing application is a combination of low speed, intermittent usage, high loads, and a lot of vibration. Due to the nature of the application it requires a grease developed and tested specifically for these requirements.
FUCHS has developed a series of greases that meet industry requirements, provide protection against wear, and have an EHL that protects during the sliding and rolling of the bearings. These greases have different viscosities so that you can choose the one that best fits your needs.
STABYL EOS E 2
This fully synthetic, high performance grease utilizing a 320 cSt base oil was developed within the WINDLUB project in Europe, which is a consortium of wind bearing, filter and lubricator companies.
STABYL EOS E 2 was specifically designed for use in heavily loaded roller and plain bearings of wind power plants. Due to its wide operating temperature range, its high mechanical stability and its outstanding load carrying capacity, STABYL EOS E 2 is excellently suitable for the lubrication of the main rotor bearings.
STABYL EOS E 2 is a grease that can provide protection against wear and an EHL that will protect during both sliding and rolling of the bearings.
STABYL LX 460 SYN
STABYL LX 460 SYN is a fully synthetic high-performance grease utilizing a 460 cSt base oil. The grease was specifically designed for use in main bearing(s) of the wind turbine. Combining the advantages of synthetic base oil, a special lithium complex thickener and a state-of-the-art additive package, STABYL LX 460 SYN reduces the wear that comes from vibration and load. The grease shows an outstanding performance throughout a wide temperature range.
This OEM approved grease has years of up tower experience and can be applied by the means of a grease gun, automatic grease dispensing units as well as central lubricating systems.
GLEITMO 680 XT
GLEITMO 680 XT is the newest main bearing grease offering from FUCHS and was designed by incorporating the newest technology oil that allows an oil with a 680 cSt viscosity to operate at the low temperatures required in Wind. It was also designed to adapt to complex lubrication issues that come with larger bearings and longer blades.
These bearings spend a high percentage of their dynamic movement in the slide regime and less in the pure rolling environment causing more wear from micro movements where the bearing is operating in the boundary lubrication phase.
GLEITMO 680 XT incorporates proprietary additive technology that better handles the sliding and highly loaded phases, lowering the wear and extending bearing life.
