What are the key benefits of an axle lube management system?

• Improved fuel efficiency through reduced churning losses.
• Lower emissions to help fleets meet sustainability goals.

• Lower axle operating temperature to protect seals, bearings and gears for extended component life.
• Compatibility with low-viscosity lubricants like 75W-80 for reduced friction.
• Enhanced real-world performance when paired with high-efficiency axles like the Meritor 14X HE.

How do fleets experience MLMS?

• No extra maintenance required—MLMS is completely self-sufficient.
• No pumps, valves, or electronics to service or inspect.
• Extended drain intervals of up to 500,000 miles with approved lubricants.
• Seamless integration into existing axle designs, enhancing performance without additional complexity.

What is the Meritor® Lube Management System?

Conventional systems rely on mechanical pumps, valves or electronic controls to manage oil flow inside the axle. MLMS takes a different route by using the axle’s own motion to manage lubricant distribution and temperature. The Meritor Lube Management System (MLMS) revolutionizes axle lubrication by using the axle’s own motion to manage oil distribution and temperature—eliminating the need for mechanical pumps, valves or electronic controls.

How does an axle lube management system work?

• Traditional axles allow the ring gear to stir oil in the sump, creating drag and heat.
• MLMS captures and channels lubricant through an integrated oil collector in the axle housing.
• Oil is guided into housing arms, which act as passive radiators, cooling the fluid before it returns to the sump via small orifices.
• Approximately two liters of oil is displaced from the sump, reducing resistance and improving efficiency.
• When the vehicle stops, oil returns to the sump within 5–7 minutes, ensuring complete drainage for maintenance.
