The bush in Sintered Steel is made with powder of steel obtained trough the powder metallurgy technology. The difference between this kind of material and more famous “Bronze” type is the volume of oil impregnation, that in this case is 25% ÷ 33% Standard Sint A00 DIN 30910. This material is more suitable in application with high load and low sliding speed.
