Renewable Energy

A term that is heard more and more is ‘going green’. We believe that some idealism is essential for being a good company, it provides guidance and adds meaning to the activities of the day. In our case part of our motivation comes from the desire to, in our own modest way, aid the reduction of pollution of the planet. This is one of the reason why we are perpetually trying to create and improve grease and oil free bearing design.

It also means that where we can, we offer our help to designers and manufacturers of renewable energy equipment. Wind energy has our special interest. For the ever growing wind mills the nacelle yaw bearings become a bottle neck and propeller pitch bearing capacity nowadays determines the dimensions of the base of the blades, instead of the optimum aerodynamic design. More efficient designs are available, maintenance free and very cost efficient.

In tidal, current and wave energy, designing the moving parts is interestingly challenging. Waves typically come in about eight second intervals, which works out to be more than 10.000 motions a day, every day, year in, year out. Try imagining what that means for a bearing. Water always contains sediment – another word for abrasive particles –, sea water is unpleasantly corrosive and every object in the sea is a target for marine growth. Not the easiest set of circumstances for mechanical moving parts. Add to that, the fact that lubrication is not an option, you cannot pollute the planet while being busy protecting it and the challenge becomes clear. We have created proven designs for a variety of renewable energy generators and if we do not yet have a required bearing in our portfolio, we will do whatever it takes to create it.
