Dingtai manufactures Yanmar-compatible idlers, the front undercarriage components that guide track movement and maintain proper track tension on excavators.
We provide factory-direct supply with full OEM manufacturing services. Global clients receive custom engineering, strict tolerances, and competitive pricing without intermediary costs.
Our idlers resist premature wear, flange cracking, and shaft failure. This reduces unplanned downtime and extends the service life of your Yanmar undercarriage.
With over 20 years of heavy machinery production experience, Dingtai holds ISO9001 and SGS certifications, ensuring consistent quality for procurement professionals.
Each idler uses premium 35MnB steel and deep quenching heat treatment to deliver high surface hardness, impact toughness, and reliable long-term performance.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB steel, the idler body delivers superior tensile strength and wear resistance in demanding working conditions.
- Deep Quenching/Heat Treatment: The tread surface is hardened to 50-58 HRC through deep quenching, extending service life under abrasive soil and rock conditions.
- Precision Forging/Casting: Single-piece forged construction eliminates porosity and structural weak points, ensuring the idler withstands heavy lateral loads.
- Global Brand Compatibility: Yanmar idlers are reverse-engineered from OEM drawings, ensuring direct replacement for ViO, SV, and B-series mini excavators.

Delivery & Logistics
We ship factory-direct with flexible order quantities, including low MOQ for stock models. Export-grade packaging and reliable logistics support delivery to global ports.
Technical Features
The idler body is precision-forged from 35MnB steel, then deep-quenched to achieve a hardened tread face. This resists abrasive wear and track link impact.
A precision-machined shaft and sealed bushing assembly maintain proper alignment. The design reduces lateral deflection and protects the undercarriage during continuous operation.
Integrated reinforced flanges prevent track derailment. This engineering extends service intervals and lowers total operating cost in high-load applications.
Applications
- Residential and commercial site preparation
- Utility trenching and underground installation
- Road maintenance and sidewalk construction
- Landscaping, grading, and material handling
- Demolition and small-scale quarry operations
Frequently Asked Questions
What is the minimum order quantity for Yanmar idlers?
MOQ is generally 1 piece for stock specifications. Custom OEM orders may require 10-20 pieces depending on tooling.
What is the delivery time?
Standard production takes 25-35 days. Stock items can ship within 7-10 days after payment confirmation.
What is the heat treatment depth?
The tread surface is hardened to 50-58 HRC, with effective depth typically 4-8 mm depending on idler size.
What warranty do you provide?
We offer a 12-month or 1,500-hour warranty against material and manufacturing defects under normal operating conditions.
Can you match Yanmar part numbers?
Yes. Provide the OEM part number or drawing, and our engineers will confirm exact dimensional compatibility before production.
What materials are used?
We use 35MnB or 40MnB forged alloy steel for the idler body, with induction-hardened tread surfaces.
Do you offer samples?
Yes, sample orders are accepted for existing stock models. Custom samples require tooling confirmation.
Maintenance Guide
- Installation: Verify mounting bracket alignment and torque bolts to Yanmar specifications. Ensure the idler rotates freely before installing tracks.
- Inspection: Check tread surface and flanges every 250 hours. Replace idlers showing deep grooves, cracks, or oil leakage from the shaft seals.
- Replacement: Replace idlers when tread wear exceeds 25% of original thickness. Always use new OEM-grade hardware for installation.
- Storage: Store idlers upright in dry conditions. Rotate the shaft monthly to prevent bearing flat-spotting during long-term inventory.
