Bronze / Brass

Manufactured using a powder metallurgy process, these bearings are created by mixing bronze powder (90% Cu, 10% Sn) with graphite (up to 20% by volume). The mixture is compacted under pressures of 200 to 1500 MPa and sintered at 850°C, resulting in self-lubricating bars and bushings with interconnected porosity of 17% to 30%. To enhance their anti-friction properties, the machined parts are submerged in an ISO 100 oil bath at 80°C and allowed to cool in the oil until they reach room temperature.

We source bars or bushings from SG Industries, specialists in producing these materials. These components are then used to manufacture self-lubricated bearings that are not exposed to percussion loads. Typical applications include automotive bearings, motors, reducers, fluid pumps, fans, couplings, refrigeration compressors, and general machine tools.
