Dingtai manufactures Mitsubishi track adjust assemblies—hydraulic tension cylinders maintaining correct track sag and absorbing undercarriage shock loads.
Factory-direct manufacturing gives global clients full OEM service, from technical drawings to finish machining, assembly, and strict quality control.
This assembly prevents track derailment and premature wear by holding consistent tension, reducing downtime and protecting idlers, sprockets, and track chains.
With over 20 years of undercarriage manufacturing experience and ISO9001/SGS-certified processes, Dingtai supplies proven reliability to demanding heavy machinery fleets.
We forge housings from 35MnB steel and apply deep induction quenching to rods and cylinders, delivering high hardness and long service life.
Core Selling Points
- OEM Capabilities: We match drawings, samples, or OEM part numbers exactly, producing track adjust assemblies with precise tolerances and full interchangeability.
- Premium 35MnB Material: Forged 35MnB steel housings provide superior tensile strength and impact resistance compared to standard carbon steel alternatives.
- Deep Quenching/Heat Treatment: Induction hardening produces HRC 50–55 wear layers on rods and bores, resisting scoring and high-pressure fatigue.
- 100% QC Inspection: Each assembly undergoes pressure testing, dimensional checks, and seal inspection before packaging, ensuring zero-defect delivery.

Technical Features
Track adjust assemblies operate as sealed grease cylinders. Pumping grease extends the piston to set track tension, eliminating manual adjustment and maintaining alignment.
A forged and induction-hardened cylinder body resists high-pressure shock loads, while a hard chrome-plated rod reduces scoring and corrosion in abrasive environments.
Polyurethane wiper seals and O-rings keep dust, mud, and moisture out, stabilizing internal pressure and extending service intervals.
Applications
- Mining and quarrying
- Road construction
- Heavy civil engineering and earthmoving
- Demolition and site preparation
- Forestry and land clearing
Frequently Asked Questions
What is the MOQ for Mitsubishi track adjust assemblies?
MOQ is 1–5 units depending on stock. Sample orders are accepted for quality verification.
How long is delivery time?
Stock items ship within 7–10 days. Production orders typically require 25–35 days before dispatch.
What heat treatment depth do you apply?
Induction hardening depth is generally 4–8 mm on cylinder bores and rods, achieving HRC 50–55.
What warranty is included?
We provide 12 months or 2,000 operating hours against manufacturing defects under normal use.
How do I match my part number?
Send your OEM part number, photos, and key dimensions. Our engineers cross-reference to the correct Dingtai assembly.
Are seals and grease fittings included?
Yes. Each complete assembly includes cylinder, piston, seals, and grease fitting unless otherwise specified.
Can you produce non-standard Mitsubishi models?
Yes, we customize based on drawings or samples to fit older, rare, or modified undercarriages.
Maintenance Guide
- Inspect weekly: Check for grease leakage, rod scoring, or housing cracks during routine undercarriage inspections.
- Adjust tension correctly: Pump grease until track sag matches manufacturer specification; do not over-tension the track chain.
- Release pressure safely: Loosen the grease valve slowly to retract the piston; stay clear of high-pressure discharge.
- Replace promptly: Replace the track adjust assembly if continuous tension loss, seal failure, or housing cracks appear.
