Abstract
The invention refers to cylindrical bearings for guiding a shaft, such as for pumps, with each bearing element comprising a centering ring made of a material having a thermal expansion coefficient higher than that of the material of the shaft (for example, polytetrafluoroethylene), arranged essentially coaxially to the shaft, with a play such that upon an appropriate process cooling step, the ring is hooped to the shaft, and at a moment that each bearing element is motionless and fixed.
