Bushing 1 x 1-1/4 x 1-1/2 Bronze sleeve bushings or bronze bushings are hard and strong, as opposed to brass bushings, which are softer and more easily deform. Thus, bronze bushings have longer lifespans than brass bushing sleeves. They resist shock, impact, wear and corrosion. They require an external lubricant, for example grease or oil, at installation and during operation to reduce friction and wear. S.A.E. 841 Bronze Material. Oil impregnated.
