Characteristic
Most commonly used bearing alloy, found in bearings operating at moderate loads and
moderate-ta-high speeds, as in electric motors and appliances. Other characteristics, material
for plain bearings in mechanical engineering with medium loads, also very good emergency
running and high wear resistance.
