Kubota track groups are complete undercarriage assemblies that integrate track chain, links, shoes, rollers, idlers, and sprockets for reliable propulsion.
We supply factory-direct Kubota track groups with full OEM manufacturing services, matching original specifications for global replacement and procurement clients.
Our track groups reduce unplanned downtime by resisting premature wear and preventing link or pin failures in demanding operating conditions.
Dingtai has over 20 years of undercarriage manufacturing experience and ISO9001/SGS certification, ensuring consistent quality control.
We use 35MnB steel and deep quenching heat treatment to extend bushing and link life under heavy load.
Core Selling Points
- Premium 35MnB Material – Links and chain are forged from high-strength 35MnB steel for improved impact resistance and longer service life under load.
- Deep Quenching/Heat Treatment – Bores and rolling surfaces receive deep induction quenching to HRC 52–60, reducing wear and elongation.
- Global Brand Compatibility – Directly interchange with Kubota KX, U, and SVL series undercarriages without modification.
- ISO9001/SGS Certified – Every batch undergoes certified QC inspection and material traceability, meeting global procurement standards.
Our catalog of Kubota Track Group includes various specifications, fully compatible with Kubota KX, U, and SVL series excavators and compact track loaders.

Technical Features
Sealed and lubricated track chain assemblies allow oil-filled pins to rotate inside hardened bushings, reducing internal friction and extending pitch life.
Deep-quenched 35MnB links resist bending and impact, while induction-hardened bushings provide surface hardness of HRC 52–60 with a tough core.
Floating seals retain lubricant and block abrasive contamination, protecting pin and bushing surfaces from premature failure in dirty environments.
Applications
- Residential and commercial construction
- Utility installation and trenching
- Road repair and asphalt maintenance
- Landscaping and site preparation
- Demolition and material handling
- Agricultural and drainage projects
Frequently Asked Questions
What is the minimum order quantity for Kubota track groups?
MOQ is one complete track group per side or one pair, subject to stock availability and custom order requirements.
How long is delivery?
Standard delivery is 15–25 days after order confirmation. Stocked specifications can ship within 7–10 days.
What heat treatment depth do you use?
Deep quench layers for links are typically 4–8 mm. Pins and bushings are induction-hardened to HRC 52–60.
What warranty policy applies?
We provide a 12-month or 2,000-operating-hour warranty against material and workmanship defects under normal use.
Can you match Kubota OEM part numbers?
Yes, we cross-reference Kubota OEM part numbers and supply equivalent track groups with full dimensional interchangeability.
Do you offer custom shoe width or link quantity?
Yes, we customize shoe widths, link counts, and bolt patterns according to your machine configuration and operating conditions.
How do I confirm the correct track group?
Send your excavator model, serial number, chain pitch, link count, or original part number for verification.
Are these track groups compatible with standard Kubota sprockets?
Yes, they are designed to interchange with standard Kubota final drive sprockets and idlers without modification.
Maintenance Guide
- Inspect: Check track sag, pin and bushing wear, and link cracks every 250 operating hours.
- Adjust Tension: Maintain track slack within Kubota-recommended limits, usually 10–20 mm between idler and top roller.
- Clean Undercarriage: Remove mud, stones, and debris from sprocket and idler cavities to prevent accelerated bushing wear.
- Replace: Replace the track group when pin leaks appear or bushing wear exceeds OEM wear limits.
