PC20-5 Sprocket Products Details

Sand casting technique to maintain internal metallographic structure.
Precise machining of fitting surfaceto ensure reliable installation andstable usage.

Key advantages

1. Superior Material & Hardness
Made of high-grade alloy steel ZG40Mn with precision quenching & tempering. Surface hardness reaches HRC 48-53 (depth 8–12 mm), delivering exceptional wear resistance and impact strength.

2. Precision Engineered Teeth
CNC-machined to OEM exact specs. Uniform tooth pitch and profile ensure smooth meshing with tracks, reduce vibration/noise, and prevent slippage for efficient power transmission.

3. Durable & Long Service Life
Deep-hardened wear surface resists abrasion, bending, and breakage even in harsh conditions (mud, rock, construction sites). Extends overall undercarriage life and lowers replacement frequency.

4. Perfect Fit & Easy Installation
Exact dimensions match PC20-5 final drive and track systems. Bolt-on design enables quick, straightforward replacement, minimizing machine downtime.

5. Reliable Quality Control
Manufactured under ISO 9001 standards with multi-stage inspections. Consistent quality ensures stable performance and reduces maintenance risks.

6. Cost-Effective Operation

Longer lifespan and reduced wear on mating parts (tracks, rollers) cut maintenance costs and improve job-site productivity.

PC20-5 Sprocket Applications

Our excavator sprockets are versatile and suitable for various construction scenarios and excavator models.

They are widely used in construction projects such as building construction, road construction, mining operations, and hydraulic engineering.

Whether it is a mini excavator used for urban landscaping and residential construction, or a large excavator used for open-pit mining and large-scale earthwork, our drive sprockets can provide stable and reliable power transmission support.

They are also essential replacement parts for excavator maintenance, ensuring the continuous and efficient operation of engineering machinery.
