Water lubricated metal and rubber bearings
Caravel bearings are made of an outer shell in brass or bronze, stainless steel, aluminium, pvc, with an inner surface covered by vulcanized NBR rubber.
Shell and rubber are carefully pasted and the adherence deeply tested in our laboratory.
Shape, dimensions and number of the lubrication channels are designed according to precise mathematical and mechanical principles. The inner design of the rubber surface can be axial, spiral or helical, with one or more right- or left-hand principles, according to the shaft rotation, to help water in its action of lubrication and cooling of the shaft.
