Dingtai manufactures Kubota track adjust assemblies, the hydraulic tensioning components that maintain correct track tension and absorb undercarriage shock loads.
We operate factory-direct with full OEM manufacturing services, supplying distributors and equipment owners across North America and global markets.
This assembly prevents track derailment, premature rail wear, and unscheduled downtime by holding consistent track tension in demanding working conditions.
With over 20 years of engineering experience and ISO9001/SGS certified processes, Dingtai delivers repeatable dimensional accuracy and proven reliability.
We use high-strength 35MnB alloy steel, deep quenching, and chrome-plated rods to ensure long service life under high-pressure track loads.
Core Selling Points
- Premium 35MnB Material: High-stress yokes and mounting brackets are forged from 35MnB alloy steel, resisting bending, fatigue, and impact damage.
- Deep Quenching/Heat Treatment: Induction hardening creates HRC 50-55 surfaces on rods and high-wear pins, extending service life in abrasive conditions.
- ISO9001/SGS Certified: Our production system follows ISO9001:2015 standards, with SGS-verified material and process quality for consistent OEM-grade output.
- 100% QC Inspection: Every assembly undergoes dimensional checks, weld inspection, and pressure testing before shipment to prevent field failures.

Technical Features
The grease-type tension cylinder uses a high-pressure seal and relief valve, allowing precise track tension adjustment while absorbing shock loads.
Chrome-plated rods and honed cylinder bores reduce friction and oil bypass, maintaining stable track tension under continuous load.
Heat-treated yokes and forged mounting ends increase fatigue strength, preventing bending or breakage in rocky and abrasive work conditions.
Applications
- Mining and quarrying
- Road and highway construction
- Demolition and site preparation
- Utility and underground contracting
- Landscaping and agricultural earthmoving
Frequently Asked Questions
What is your minimum order quantity for Kubota track adjust assemblies?
Our standard MOQ is one to two pieces for stock replacement. OEM custom orders may require higher quantities based on machining setup.
What is the typical delivery time?
Standard assemblies ship within 15–30 days after deposit confirmation. Custom-machined orders may require 25–40 days depending on specification.
How deep is the heat treatment on rods and yokes?
Induction hardening depth typically ranges from 1.5 mm to 3.0 mm on high-stress zones, with HRC 50–55 surface hardness.
What warranty do you provide?
We provide a 12-month or 2,000-hour warranty against material and workmanship defects under normal operating conditions.
How do I match the correct part number?
Provide your Kubota OEM part number, machine model, or a dimensional drawing. Our engineers cross-reference exact interchange specifications.
Do you supply seals and installation components?
Yes, each assembly includes the required high-pressure seals, grease fitting, and mounting hardware unless otherwise specified.
How do you ensure quality before shipment?
Every unit undergoes dimensional inspection, weld testing, and pressure retention testing to verify seal performance and structural integrity.
Maintenance Guide
- Check track tension daily using the Kubota sag specification; adjust through the grease fitting as needed.
- Inspect the cylinder rod and seals for leakage, scoring, or dents before each shift.
- Release grease pressure safely before removing the adjust assembly; avoid over-tensioning track chains.
- Replace the assembly if track tension cannot be held or if the cylinder body shows visible cracks or damage.
