Heat Resistant Piston Ring for Bedford MOT500 Corrad - 115.888mm Diameter, 0.021mm Precision

• High Temperature Coating: Enhanced heat resistance and superior lubrication performance for high-temperature environments
• Low Friction Coating: Reduces friction loss, improves engine efficiency, and saves energy

Piston rings feature precisely engineered grooves and gaps that guide the flow of lubricating oil and coolant. These channels transport optimal amounts of lubrication and cooling fluids to friction surfaces at the top and bottom of the piston, ensuring sufficient lubrication and cooling effects while reducing friction, heat buildup, and wear.

The piston ring effectively balances piston surface temperature, minimizing thermal stress and heat loss through strategically placed grooves and gaps that direct lubricating oil and coolant to critical friction surfaces.

Typically composed of multiple rings with close side connections, common configurations include oil rings, oil control rings, and upper/lower spiral grooves. Each structural variation serves specific functions including cylinder sealing, heat conduction, and lubrication.
