Strengthening metal against fatigue

A team of researchers at MIT and in Japan and Germany has found a way to greatly reduce the effects of fatigue by incorporating a laminated nanostructure into the steel.

SKF offers new high-performance seal option on a range of bearings

SKF is making its high-performance RSH seal design available on a larger range of SKF Explorer deep-groove ball bearings. The tried and tested RSH seal uses a highly optimized dual-lip configuration to provide additional protection in demanding environments. For users, the result is bearings that last longer, especially in wet, contaminated or dusty operating conditions,

High reliability roller bearings reduces operation costs for wind turbines

In 2003, NSK developed the range of rolling bearings for this industry and named it as “Wind Standard U303”.

Lessons learned lead to new ideas in gearbox bearings

By Michelle Froese, Senior Editor Windpower Engineering & Development Gearboxes have long taken blame as the typical cause for a wind-turbine failure, and for good reason. Many gearboxes fail to pass the five-year mark without need for component repairs or full replacement. But when the wind industry first got its start, few considered the high

Tips for extending bearing life in wind turbines

Gearbox reliability has improved remarkably in the last 10 years thanks to a better understanding of bearing loads. However, even high-quality components have a limited life expectancy in the wind industry so it is important to have a consistent maintenance plan in place. In this Wind Talk podcast, The Timken Company‘s Rick Brooks discusses new trends

What different kinds of bearings are used in wind turbines?

A wide range of bearings perform different functions throughout a wind turbine. For instance:

The case for case carburized bearings in wind turbines

Case-carburized bearings have distinct advantages over through-hardened versions. Case studies presented here suggest properties to request in the specification for gearbox replacement bearings.

Wind-driven aerators run better with Vesconite bearings

Vesconite says its bearings last up to 10x the life of bronze bushes, and they don’t swell so they work where nylon is unsuitable. May be the best material for dirty and poorly lubricated conditions.

Timken expands line of small-bore metric seals

The catalog is available online at Timken.com/catalogs and through the Timken catalog app at http://timkencatalogs.squawqr.com/.

Making short lived pitch bearing work longer

Let’s start with the function of a pitch bearing, which is to allow for variable pitch position of the turbine blade and to transmit blade loads into the hub.
