Standard and bespoke bearings for wind turbines
ind turbines are still comparatively new in technology terms, so the problem of maintaining and re-conditioning them is a relatively recent
one. What is generally not appreciated is that they have a finite service life, as evidenced by the first generation of turbines installed 10-years ago, or longer, that now require maintenance and overhaul. These maintenance procedures usually involve a gearbox
rebuild and replacement of large shaft bearings. However, unlike new builds, the maintenance projects have to be completed as quickly as possible, to minimise the generation downtime. Moreover, companies are often awarded repair business
contracts at the last minute after tender, and so need to source the repair parts quickly, because it would be extremely expensive to keep an inventory for all service parts on the shelf. While the UK is not a leader in the manufacture of wind
turbines, one British company is becoming indispensable to the specialist service companies that repair and maintain them. Thanks to its ability to manufacture large diameter
replacement bearings in a fraction of the time required by the international bearing manufacturers, Revolvo is helping wind turbine maintenance companies to meet very tight deadlines. Flexible production at the company’s brand new
manufacturing facility allows it to supply standard or bespoke solid and split bearings – to order – in sizes up to 1.5metres outside diameter in a matter of weeks. This is where Revolvo can help. Known for its range of SRB
split roller bearings, Revolvo,also manufactures large, OE-standard solid bearings – cylindrical, taper roller, thrust and deep groove ball bearings –and can deliver them in a fraction of the lead-time of the large international bearing manufacturers, often in a matter of weeks. This means that refurbishment projects can be delivered on-time and within budget by sourcing the bearings required for wind-turbine transmissions directly from the company. Revolvo manufactures solid bearings in sizes from 25mm
bore to 1500mm external diameter, and SRB split roller bearings in sizes from 35mm bore to over 1000mm internal diameter, plus imperial equivalents. In addition, the company makes bespoke and obsolete sizes of solid ball and roller bearings. l
Revolvo is based inDudley, West Midlands, UK.
