Bronze insert rings are recommended for use in situations where condensation can be a problem or where the ring may come into contact with elements that would be corrosive to cast iron. Bronze also has a tendency to expand faster than cast iron which is beneficial during periods of momentary losses of lubrication.

Other advantages are reduced ring breakage as well as reduced cylinder wear because of its low coefficient of friction and high coefficient of thermal conductivity (heat transfer) characteristics.

The protruding bronze surface is able to glide over dry spots on the cylinder wall that may have little or no lubrication while accelerating the transfer of heat from the piston and ring to the cylinder wall with subsequent cooling.

Available in butt, angle, and step cuts.
