Atro Polyurethane Mack Trunnion Bushing MA10000

The ATRO MA10000 is a premium heavy-duty trunnion bushing engineered specifically for the Mack Camelback Suspension. While standard rubber bushings degrade when exposed to grease, oil, and road chemicals, ATRO’s proprietary high-quality polyurethane is designed to be impervious to these elements.

Proudly Made in the USA, this bushing provides superior vibration dampening and maintains its shape longer than OEM rubber, reducing downtime and maintenance costs for your fleet.

Product Features:

• Superior Material: ATRO Polyurethane is chemically resistant to oil, grease, salt, and hydraulic fluids.

• Enhanced Durability: Engineered to withstand the heavy oscillation loads of the Mack Camelback system.

• Direct Replacement: Precision-molded to meet or exceed OEM specifications.

• Fleet Efficiency: Reduces the frequency of bushing replacements, keeping your trucks on the road longer.

Why Choose ATRO Polyurethane?

Rubber bushings often fail because they are "bonded" and tear over time, or they simply rot away from chemical exposure. ATRO bushings are not bonded; they are designed to rotate and absorb impact without the internal stress that causes rubber to fail. When you install an ATRO MA10000, you are installing a part designed to outlast the competition.
