Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The bottom roller, also known as the track roller, is a critical undercarriage part that carries the weight of the excavator and ensures smooth movement of the track chain. For compact models such as U008 and U10, the roller must handle frequent directional changes, confined-space operations, and challenging terrains. A high-quality roller ensures reduced vibration, lower wear on track links, and stable operation of the entire machine.
Material and Heat Treatment
Our U008/U10 bottom rollers are manufactured using high-grade alloy steel with excellent toughness and wear resistance. After forging, the roller surface undergoes deep heat treatment, reaching a hardness of HRC52-58 on the wear surface. This process significantly improves the roller’s resistance to abrasion, impact, and deformation, ensuring long service life under demanding jobsite conditions.
Manufacturing Process
The Kubota track rollers are produced through a controlled step-by-step process:
Heat Treatment
Machining Process
CNC turning and milling ensure dimensional accuracy
Assembly
Running Test
Simulated load test to verify functionality
Paint Spraying
Anti-rust coating for surface protection
Packing
Precision Machining and Assembly
Every roller body is CNC-machined to maintain dimensional accuracy and smooth track contact. Bushings and shafts are ground and polished to reduce friction, while high-precision bearings are used for consistent load distribution. During assembly, strict tolerances are followed to ensure a perfect fit, preventing premature wear and operational instability.
Advanced Sealing System
Compact excavators often work in muddy, dusty, or wet environments, which can quickly damage rollers without proper protection. To solve this, our U008/U10 rollers adopt a dual-lip floating seal system that prevents grease leakage and blocks the intrusion of dirt, water, and abrasive particles. This sealing technology guarantees long-lasting lubrication and reduces the need for frequent maintenance.
