3222 3490 02 Bottom Roller For Road Construction Machine Undercarriage Parts

Track rollers, also known as lower or bottom rollers, are designed to transfer most of the machine's weight and dynamic forces to the ground through the tracks. Forged from deep hardened steel, they are heat treated to increase internal strength to resist bell-mounting and improve rebuildability. Heat-treated housings increase body strength and extend service life.

Features:

Made from special high-strength hardened steel and premium seals, the roller offers strength, durability, and high performance.

The tread and flange areas of the rollers are heat treated to increase strength and extend wear life.

The drum is equipped with a white dust-proof plug to prevent damage from oil and sand.

OEM quality: All product dimensions strictly follow OEM. We will also do a final inspection before shipping to avoid any issues.
