OEM HITACHI ZAXIS ZX50 SERIES BOTTOM TRACK ROLLER | Tonkee®

The bottom track roller for the Hitachi Zaxis ZX50 Series is engineered to meet the demanding requirements of the construction industry.

It is typically constructed from high-quality materials such as forged steel or cast iron, known for their excellent strength and durability. These materials ensure that the roller can withstand the constant wear and tear it experiences during operation.

Design:
The design of the bottom track roller is intricate and precise. It typically consists of a central shaft, a set of bearings, a roller shell, and seals. The roller shell is what comes in direct contact with the excavator's steel tracks, allowing for smooth rolling motion. The bearings within the roller ensure low friction and efficient movement, while seals protect the bearings from contamination, extending their lifespan.

Function:
The primary function of the bottom track roller is to support the weight of the excavator and distribute it evenly across the undercarriage. This support is essential for maintaining stability and preventing excessive wear on the tracks. It also assists in propelling the machine forward and backward by rolling along the terrain.

Load-bearing Capacity: The bottom track roller is designed to bear heavy loads, making it suitable for the demanding tasks encountered in construction and excavation work.

Maintenance-Friendly: Many bottom track rollers are designed for easy maintenance.

They often have lubrication points that allow for the periodic greasing of bearings, ensuring smooth operation and extending component life.

Dust and Debris Protection: Seals are integrated into the design to prevent dust, dirt, and debris from entering the bearing housing. This protection is crucial for maintaining the integrity of the bearings.

Abrasion Resistance: The roller shell is engineered to be highly resistant to abrasion, which is critical since it comes into direct contact with the abrasive surface of the steel tracks.

Compatibility:
The Hitachi Zaxis ZX50 Series bottom track roller is specifically designed to fit these excavators. Compatibility is vital to ensure that the roller seamlessly integrates with the machine's undercarriage system, providing optimal performance.
