The Mitsubishi Bulldozer Idler is a heavy-duty front guide wheel maintaining track tension and absorbing impact during dozing operations.
We supply factory-direct idlers with full OEM manufacturing support, custom dimensions, and strict quality control for global equipment buyers.
These idlers prevent premature undercarriage wear, reduce track derailment risk, and eliminate costly downtime caused by inferior aftermarket components.
Dingtai brings over 20 years of engineering experience, ISO9001-certified processes, and SGS-verified material test reports to every production batch.
Each idler uses premium 35MnB steel and deep induction quenching for hardened wear surfaces, tough cores, and high fatigue resistance.
Core Selling Points
- Premium 35MnB Material – We use high-tensile 35MnB steel with strict chemical composition control to withstand heavy shock loads and abrasive undercarriage conditions.
- Deep Quenching/Heat Treatment – Induction hardening penetrates wear surfaces to 4–8 mm depth, achieving HRC 52–58 for extended service life under continuous friction.
- OEM Capabilities – Factory-direct production matches OEM drawings, sample parts, or serial numbers, ensuring exact dimensional fit for Mitsubishi bulldozers.
- 100% QC Inspection – Every idler undergoes dimensional inspection, ultrasonic flaw detection, and hardness testing before packing to eliminate field failures.
Our catalog of Mitsubishi Bulldozer Idlers includes various specifications, fully compatible with Mitsubishi bulldozers.

Technical Features
The idler rim is precision forged from 35MnB steel, then induction hardened to create a wear-resistant shell and tough core.
Floating seal design keeps lubricant inside the shaft cavity while blocking abrasive dirt, moisture, and fine rock particles.
Bimetallic bushings provide low-friction rotation and reduce shaft wear under continuous high-load idler operation in abrasive environments.
Applications
- Mining: Hard rock and overburden removal.
- Road Construction: Subgrade and embankment compaction.
- Quarrying: Aggregate and blasted rock handling.
- Forestry: Clearing and slope work.
- Landfill: Waste compaction and daily cover.
Frequently Asked Questions
What is the minimum order quantity for Mitsubishi bulldozer idlers?
MOQ is 1 piece for sample evaluation. Bulk order pricing typically starts from 10 pieces per specification.
How long is delivery time?

Induction hardening depth is 4–8 mm with surface hardness HRC 52–58.
What warranty policy applies?
We provide 12 months from shipment against material and workmanship defects under normal operating conditions.
How do I confirm part number matching?
Send your OEM part number, idler drawings, or machine serial number; our engineers cross-reference before quoting.
Can you produce custom idler dimensions?
Yes, we manufacture to customer drawings, samples, or reverse-engineered dimensions with full dimensional reports.
Maintenance Guide
- Check track sag daily and adjust idler position to maintain manufacturer-recommended tension limits.
- Inspect idler tread, flanges, and welds for cracks, spalling, or uneven wear before each shift.
- Grease sealed idler hub at specified intervals and immediately investigate any oil or grease leakage.
- Replace idler when wear exceeds OEM wear limits, or when floating seals fail and allow contamination ingress.
