Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Track rollers (also known as bottom rollers) are a key component of the Kubota U30 mini excavator undercarriage. Their primary function is to bear the machine's weight and maintain track chain alignment during operation. Durable and well-sealed rollers help reduce vibration, extend track life, and ensure stable mobility for the mini excavator whether operating on urban construction sites, farmland, or mixed terrain. Kinton Parts provides reliable quality Kubota excavator track rollers through consistent manufacturing processes.
Material & Heat Treatment
Our Kubota U30 track rollers are manufactured from high-quality forged alloy steel, offering an excellent balance of toughness and hardness. After CNC precision machining, the roller undergoes surface induction hardening (HRC52–58) for outstanding wear resistance. The core remains tough to absorb impact forces, while the working surface withstands constant abrasion from the track chain. Finally, an anti-rust coating is applied to protect against corrosion in wet or muddy environments.
Manufacturing Process
The Kubota U30 bottom roller is 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
