D-glide maintenance free composite plain bearings can in all respects match conventional metallic plain bearings. Loads can in many cases be higher, friction is lower and wear is less. All without lubrication or any other form of maintenance. We provide also the knowledge to make optimum composite materials. This can range from selecting the right D-glide quality for the steering system of a truck, to designing the complete bearing construction for 600 tons offshore sheaves.
