Product Definition: Dingtai manufactures Kato track adjust assemblies, the hydraulic cylinders that control track tension within excavator undercarriage systems.
Service Advantage: Factory-direct production supports global OEM replacement with CNC machining, precision assembly, and dimensional control for Kato excavators.
Problem Solved: Hardened cylinders and heavy-duty seals prevent track derailment, reduce downtime, and resist high-pressure grease leakage in demanding applications.
Why Us: With over 20 years of undercarriage manufacturing experience, Dingtai holds ISO9001 and SGS certifications, ensuring reliable batch consistency.
Technology: 35MnB forged steel and deep induction quenching deliver HRC 50-55 surface hardness, extending service life under high-impact loads.
Core Selling Points
- Premium 35MnB Material: Forged 35MnB alloy steel provides high tensile strength and fatigue resistance for repeated track tensioning cycles.
- Deep Quenching/Heat Treatment: Induction hardening produces HRC 50-55 on cylinder rods and yokes, reducing scoring and premature wear.
- ISO9001/SGS Certified: ISO9001 quality systems and SGS material reports verify every batch meets export and OEM inspection standards.
- 100% QC Inspection: Each assembly undergoes dimension checks, pressure testing, and visual inspection before crating to guarantee field performance.
Our catalog of Kato Track Adjust Assembly parts includes various specifications, fully compatible with Kato HD-series excavators and selected tracked machines.

Technical Features
The track adjust cylinder converts grease pressure into linear force, pushing the idler forward to maintain correct track sag and prevent derailment.
Heavy-duty seals sustain high working pressure without leakage; the induction-hardened rod resists scoring from fine abrasive particles.
Forged 35MnB yoke and cylinder body provide impact toughness, preventing cracks during rock excavation and heavy load cycles.
Applications
- Mining excavation and quarrying
- Road construction and site preparation
- Demolition and scrap handling
- Forestry and heavy earthmoving
- Utility and pipeline projects
Frequently Asked Questions
Q1: What is the MOQ for Kato track adjust assemblies?
A: Trial orders start at 1 unit; mixed model orders are accepted.
Q2: What is the delivery time?
A: Stock items ship in 3-5 days; custom production takes 20-30 days depending on quantity.
Q3: How deep is the heat treatment?
A: Induction hardening depth reaches 3-5 mm, producing HRC 50-55 on wear surfaces.
Q4: What warranty policy applies?
A: 12 months or 2,000 operating hours against material and manufacturing defects under normal use.
Q5: How do I match part numbers?
A: Provide the OEM part number, machine model, or drawing. Our engineers confirm dimensional interchange before production.
Q6: Are seal kits available?
A: Yes, replacement seal kits are available, and assemblies can be rebuilt to reduce operating costs.
Q7: Can you supply material certificates?
A: SGS and mill test certificates are supplied with bulk orders or on request.
Maintenance Guide
- Installation: Clean mounting bores and grease fill port before installation; apply anti-seize to mounting bolts.
- Tension Adjustment: Pump grease until track sag measures 20-30 mm between carrier rollers; avoid over-tensioning.
- Inspection: Check for grease leakage around the rod seal every 250 service hours.
- Replacement: Replace the assembly if cylinder body cracks, scoring depth exceeds 2 mm, or yoke wear is excessive.
