Our Caterpillar sprocket is a precision drive component that meshes with the track chain, propelling excavators and bulldozers through severe terrain.
We operate a factory-direct model, providing comprehensive OEM sprocket manufacturing with custom branding, packaging, and engineering support for global distributors.
Our sprockets use deep-hardened profiles to resist abrasive wear, significantly reducing replacement frequency and avoiding unscheduled downtime in heavy-duty operations.
With 20+ years of foundry expertise and ISO9001/SGS certifications, Dingtai delivers sprockets that meet strict OEM durability and dimensional standards.
Forged from 35MnB steel, our sprockets receive deep quenching for a hardened case depth of 4–8 mm, delivering exceptional impact and wear resistance.
- Premium 35MnB Material
All drive sprockets are manufactured from high-toughness 35MnB steel, providing excellent shock load absorption and superior bending fatigue strength. - Deep Quenching/Heat Treatment
Tooth flanks undergo deep induction hardening to 4–8 mm case depth, achieving 50–60 HRC hardness while preserving a tough ductile core. - Precision Forging
Each sprocket is precision forged to net shape, guaranteeing smooth chain engagement and minimal track link wear under heavy loads. - OEM Capabilities
We support full OEM customization, including branding, packaging, and exact dimensional matching to your drawings or samples, with rigorous QC.
Our catalog of Caterpillar Sprocket includes various specifications, fully compatible with Caterpillar excavators and bulldozers across all series.

Technical Features
The involute tooth profile is precision machined to match the track chain pitch perfectly, distributing load evenly and minimizing stress concentration.
Induction hardening creates a deep hardened case on tooth flanks while preserving core toughness, preventing brittle fracture under impact.
The forged grain flow follows the tooth contour, significantly enhancing fatigue resistance compared to cast or machined-from-bar sprockets.
Applications
- Mining and quarrying
- Heavy civil construction
- Road and railway building
- Forestry and land clearing
- Demolition and material handling
Frequently Asked Questions
- What is the minimum order quantity (MOQ) for Caterpillar sprockets?
- Our standard MOQ is 10 pieces per part number, with flexible options for trial orders of 1–2 pieces for first-time customers.
- How long is the delivery time?
- Standard delivery is 25–30 days after order confirmation; express production can ship in 15–20 days depending on current capacity.
- What heat treatment depth do your sprockets achieve?
- Tooth flanks receive deep induction hardening to a case depth of 4–8 mm, achieving 50–60 HRC surface hardness while maintaining core toughness.
- Do you offer warranty on sprockets?
- Yes, we provide a 12-month or 2,000 operating hour warranty against material and manufacturing defects under normal use conditions.
- Can you match existing part numbers?
- Absolutely. We can manufacture sprockets to original CAT part numbers, and cross-reference samples or drawings for precise compatibility.
- Do you provide material certificates?
- Yes, we supply mill test certificates and SGS reports for each shipment to confirm 35MnB material composition.
- Are your sprockets suitable for extreme mining conditions?
- Yes, our deep hardened sprockets are specifically designed for high-impact and abrasive environments common in mining and quarrying.
- What packaging do you use for export?
- Each sprocket is wrapped in anti-rust paper and packed in plywood crates with fumigation-free certification for safe ocean transit.
Maintenance Guide
- Before installation, clean the sprocket mounting surface and verify bolt hole alignment to ensure proper seating and torque retention.
- Replace sprocket when tooth tips become pointed and track chain elongation exceeds 3%, preventing costly undercarriage damage.
- In heavy-duty applications, inspect every 500 operating hours; typical service life ranges from 2,000 to 4,000 hours depending on ground conditions.
