Electrical erosion is a common cause of bearing failure – something that can lead to complications for wind farm operators, such as downtime or reduced productivity. However, there is a cost-effective solution to this. SKF collaborated with a wind turbine generator manufacturer to resolve the issue.

In order for a wind turbine bearing to be as effective and durable as possible, it must be tested thoroughly. This is not always an easy task, with few facilities having the capabilities to put large-size bearings through their paces. SKF recently built and opened the world’s most powerful test center for this purpose.

Not all old parts have to be replaced. SKF bearing remanufacturing services can extend service life – so you can reduce lifecycle costs and environmental impact.

Operation and maintenance (O&M) costs can constitute up to 25% of a turbine’s levelized energy cost over its lifetime. Technology that helps reduce maintenance and downtime is therefore crucial. In the previous article of this two-part series, we examined four of the most common bearing failure modes. This time, we will look at black oxidation – an effective solution to improve operational reliability.

White etching cracks are a symptom of bearing failure. SKF researchers and application engineers discuss how to tackle the challenges and reduce the risk of this failure mode.

The reliability of bearings has a profound impact on wind turbine operating costs. But as the parts are often subjected to a wide variety of operating conditions, they may fail when they are pushed beyond their limits. In fact, in the past, as many as 80 percent of wind gearbox failures were caused by faulty bearings. Here are the top four main failure modes.

Whether onshore or offshore, in a desert or on a mountain, wind turbines are exposed to harsh conditions. Around the world, SKF lubrication solutions help operators to improve system reliability. Discover the benefits.

Bearings are among the most essential components in wind turbines. If a fault occurs in a turbine bearing, it could result in significant financial losses for everyone involved in the wind power supply chain. A major breakdown could cause widespread disruption, affecting the energy supply of a large organization – or even an entire region. Keeping these parts performing efficiently and reliably is therefore of utmost importance.

In the wind power industry, each hour a turbine remains out of operation equates to an hour of lost revenue. Minimizing downtime is therefore a top priority for everyone involved in the sector. Keeping turbines running requires knowledge, care, and vigilance.
