Hydro lubricated rubber bronze bearing 50 mm Caravel

Length of the bearing is 200 mm

Outside diameter 70 mm

Caravel bearings are made of an outer shell in bronze 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.

Easy assembling and replacement

Caravel water lubricated bearings meet every requirement in terms of inner and outer tolerance: when needed, they are grinded externally, to be assembled and replaced very fast.

Noise and vibrations damping

Water lubricated bearings are the ideal solution to limit and keep under control vibrations and noise: such a feature plays an important role on propeller shafts and industrial applications. It may happen that turning bodies are not perfectly balanced or extreme precision is required.
When the shaft’s rotation around its own axis does not coincide with its geometric center, the rubber’s extreme elasticity absorbs the vibrations in a very effective way. Laboratory tests have proved that vibrations do not spread to the outer shell. The NBR rubber is ideal to prevent damages and shaft.
