Bushing is a bearing between movable and immovable components. These spare parts function to hold the shaft rotated by the motor and through the gear box, from the gear box into the shaft that is held by the brass material bushing, which will be able to reduce vibrations and the shock of shock loads. The purpose of this research is to know the level of roughness and wear rate of brass bushing, this research is to find out how efficient it is, the use of a bushing with a field that is very likely to have a large shock load and to know the wear test data, roughness, of the brass bushing. This type of research uses an experimental method, from the results of the study it is concluded that to get the roughness and wear value using a conventional lathe, the spindle rotation is 970 rpm. Based on experimental experiments with predetermined parameters, the lowest roughness value is Ra 1.13 and the highest roughness is Ra 2.41. Experimental experiments for the wear test of each specimen obtained the wear rate after the initial weight was subtracted from the third one hour weight, from the smallest weight of 0.07 grams and the largest weight of 1.62 grams.
