Bronze Bearing Material on Friction Properties of Oilless Bearings

Tin Bronze & Vanadium-titanium Ductile Iron & Cast Iron

The friction coefficient of tin bronze is the lowest, followed by vanadium-titanium ductile iron, and the highest friction coefficient of ordinary cast iron is 0.2, and the changes in load and speed have little effect on them.

The tin bronze bearing has a wide range of load and speed, but the friction coefficient is stable. When the PV value of vanadium titanium ductile iron exceeds 700kg/cm, and the PV value of ordinary cast iron exceeds 600kg/cm, the temperature will rise rapidly, causing the bearing to become unstable.

Instability behavior of Oil-free bearings

When the load is less than a certain value, the bearing works very stably, and the friction coefficient is unchanged. When the load exceeds a certain value, the bearing will become unstable, and the friction coefficient and temperature will increase rapidly. For tin bronze bearings, instability is due to The worn copper powder accumulating. Under certain pressure and temperature, the copper powder will combine to form a film covering the surface of the solid lubricant, so that the embedded solid lubricant cannot continue to play a lubricating role, resulting in lubrication failure.

C93200 SAE 660 Bearing Bronze Used for Light Applications

C93200 bearing bronze is easily machined into several different kinds of custom bronze components, as it is considered one of the standard bearing bronze alloys for light applications and is less dependent on lubrication.

SAE 660 bearing bronze’s resistance to corrosion makes it an option for marine parts, but CDA 954 aluminum bronze and CDA 955 nickel aluminum bronze are the strongest bronze alloys on the market for long-lasting non-corroding marine parts for ships and military-grade bronze components.

High Leaded Tin Bronze

CDA 932 660 bearing bronze copper alloy is a high leaded tin bronze with trace amounts of iron, nickel, and antimony, making it an absolute workhorse of a bearing bronze alloy. It features excellent machining properties, good hardness, wear resistance, and great anti-friction qualities. CDA 932 is not subject to dezincification and has decent corrosion resistance to brine and seawater.
