The renewable energy sector is being forced to reduce the levelized cost of electricity (LCoE). The wind energy industry is striving to match or exceed the LCoE of traditional energy sources. Due to the cost of the equipment combined with the lower relative operations and maintenance costs compared to traditional energy, the driving factors in reducing the LCoE in wind are the costs of the equipment and uptime. Uptime in wind turbines is critical to the future of the energy source. In the past years, SKF scientists and research engineers conducted systematic investigation and verification tests on key parameters, which may have strong contribution to the main-shaft bearing performance. To reduce the risk of lubrication starvation, SKF NoWear surface coating has been selected and verified, which can not only increase the wear resistance on the raceway surfaces, but also reduce the friction and therefore prolong the grease life. NoWear testing has shown performance upgrades by reducing wear in the starved condition, and more critically to overall asset life, extending the time to starvation when compared to a non-coated roller bearing. SKF NoWear is a wear resistant metal-containi...
