Track Roller for Doosan DH220 2270-1098

At Quanzhou Qiansheng Heavy Industry Machinery Co., Ltd., we specialize in manufacturing durable undercarriage parts for excavators and bulldozers. The Track Roller for Doosan DH220 2270-1098  is one of our core products developed for demanding working conditions where machine stability, wear resistance, and long operating life are essential.

This bottom roller is engineered to support the full operating weight of the excavator while ensuring smooth track movement across rough terrain. Whether your equipment operates in mining sites, quarry projects, road construction, or large-scale earthmoving environments, our track roller is built to maintain reliable performance under continuous heavy loads.

Unlike low-cost aftermarket rollers that often suffer from premature leakage, shell cracking, or uneven wear, our products are manufactured under strict quality control processes using carefully selected raw materials and advanced production equipment.

Why  Choose Our Track Roller for Doosan DH220 2270-1098

High-Strength Forged Steel Structure

We use high-quality 40Mn2 and 50Mn alloy steel materials combined with precision forging technology to improve structural strength and impact resistance. This helps prevent deformation and cracking during long-term heavy-duty operation.

Advanced Heat Treatment Technology

The roller surface undergoes medium-frequency induction hardening to achieve excellent hardness and deeper wear-resistant layers. This process significantly improves durability in abrasive working environments such as mining and quarry operations.

Surface Hardness:  HRC 52-58
Hardening Depth:  5-8 mm

The enhanced hardness extends service life and helps reduce equipment downtime and replacement frequency.

Stable Sealing Performance

Our Track Roller for Doosan DH220 2270-1098  is equipped with high-quality floating seals and precision bushings to effectively prevent oil leakage, dust intrusion, and water contamination.

The sealing system is designed to maintain lubrication stability even under muddy, wet, or dusty jobsite conditions.

Precision Machining for Accurate Fitment

All rollers are processed by CNC machining centers to ensure accurate dimensions and stable installation performance. The product is manufactured according to OEM specifications for direct replacement compatibility with Doosan DH220 excavators.

No modification is required during installation.
