The YM2D07 Excavator Bottom Roller is a heavy-duty undercarriage replacement component designed for YANMAR excavators operating in demanding environments. Developed with high-strength alloy steel and advanced manufacturing technology, this bottom roller provides excellent load-bearing capability, structural durability, and stable performance under continuous working conditions.

Designed to support the full operating weight of crawler excavators, the YM2D07 lower roller helps maintain proper track alignment, reduce vibration, and improve overall undercarriage reliability. It is an ideal replacement solution for construction contractors, machinery repair companies, and spare parts distributors requiring dependable aftermarket components.

During excavation, mining, and construction operations, bottom rollers are exposed to:

• Heavy machine loads
• Continuous impact forces
• Abrasive soil and rocks
• Mud and moisture
• Long working cycles

The YANMAR YM2D07 bottom roller is manufactured to withstand these challenges by combining high-strength materials, precision machining, and optimized sealing technology.

Main Performance Characteristics

Reinforced Load-bearing Structure

The YM2D07 bottom roller features a heavy-duty structural design capable of supporting high machine weight and repeated operating pressure.

The optimized roller body improves:
