Sintered Bronze

The bush in Sintered Bronze give a wide range of applications, is realized with a powder of bronze sintered, calibrated and impregnated into specific oil (volume of impregnation of 25% ÷ 29% as per DIN 30910 Sint A50). During the application, this kind of material, thanks’ to the oil impregnation, developes a film of lubricant oil, between the shaft and the bush.
