Pelamis’ first wave energy converter (P1) was a simpler design with separated hinged joints. Although this arrangement allowed useful working space between the axes, it had to carry high transferred loads and was unable to manage the combined motions needed for the P2 configuration. Also, the bearings themselves were relatively Low friction bearings, affecting efficiency.

But how can you secure a spinning shaft? In the early days, up to 14 large metal collars containing low friction bearings were placed along the propeller shaft to attach it to the hull. Unfortunately these overheated because of friction between the shaft, the bearing and the collar.

Eco-friendliness is a modern way to describe any equipment that makes the attempt to leave the environment untouched or unharmed. In regard to commercial vehicles, it can be an innovative mechanical feature that is trying to cut fuel consumption, decrease carbon dioxide emission and significantly improve overall engine performance. Carbon dioxide emissions have drastically increased due to human activity. In response to this environmental problem, the automotive industry and some engineering companies have designed and introduced eco-friendly utility equipment such as hybrid vehicles skf bearings . These innovative vehicles can lead the way in terms of cost-effectiveness with the contribution to the cause of lower oil consumption and longer vehicle mileage.

Turbocharger – This is another innovative development utilizing ceramic rolling balls. It is not difficult to assemble and has a parallel ntn bearing arrangement to minimize frictional loss. This fact reduces fuel consumption and decreases carbon dioxide emissions in comparison to the usual such components. An additional feature includes the integration of wear-resistant ceramic rolling elements that can endure extreme temperatures, minimize noise and have high loading capacity when running at high speeds. The unit is made of aerospace-quality steel, reinforced steel and sports a polymer cage design. This modern ball bearing unit is thought to improve overall engine performance, improve running accuracy and improve fuel efficiency.
