  • Understanding Journal Bearings - EDGE

    Bearings are used to prevent friction between parts during relative movement. In machinery they fall into two primary categories: anti-friction or rolling element bearings and hydrodynamic journal bearings. The primary function of a bearing is to carry load between a rotor and the case with as little wear as possible.

    Copper-cadmium alloys which have almost double the mechanical strength and wear resistance of pure copper, yet still retain 90 per cent of its conductivity, contain between 0.8 to 1.2 per cent cadmium. In addition, copper-cadmium alloys can be severely cold rolled without making them susceptible to softening during soldering.
