The benefits of oilless bronze 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 of 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.
