Sprocket for Kobelco SK200-8 YN51D01003P1

As a direct manufacturer, we supply Sprocket for Kobelco SK200-8 YN51D01003P1  built for real working conditions, not laboratory assumptions. Based on long-term export feedback from mining and earthmoving customers, this sprocket is designed to maintain stable track engagement under continuous load, reducing downtime caused by tooth wear or misalignment.

Core Manufacturing Experience

In our Quanzhou production base, every sprocket is produced under full-process control—casting, CNC machining, and induction hardening.

We have repeatedly observed in field operations that many aftermarket parts fail early due to uneven hardness and poor tooth geometry. To avoid this, our Sprocket for Kobelco SK200-8 YN51D01003P1  adopts:

· 35MnB / 50Mn alloy steel casting for structural strength

· CNC-machined pitch accuracy for smooth track engagement

· Localized induction hardening on tooth surface only

· Internal ductile core to absorb shock load

This structure balances wear resistance and impact toughness, especially in muddy or rocky conditions.

Technical Specifications

· OEM Part No.: YN51D01003P1

· Applicable Model: Kobelco SK200-8 / SK210-8

· Material: 35MnB / 50Mn Alloy Steel

· Hardness: HRC 50–55

· Process: Forging + CNC machining + induction quenching

· Testing: 100% UT & MT inspection before shipment

· Service Life: 2000+ working hours (based on field feedback)

Real Working Performance

Based on customer feedback from Southeast Asia and Middle East mining sites, our sprocket shows:

· Lower tooth skipping rate under heavy load

· More stable track tension retention

· Reduced vibration during high-speed travel

· Longer replacement cycle compared to standard aftermarket parts

Compared with low-cost sprockets in the market, many alternatives only harden the surface shallowly, causing cracking or premature tooth rounding. Our design avoids this issue by controlling heat treatment depth precisely.

Application

The Sprocket for Kobelco SK200-8 YN51D01003P1  is widely used in:

· Excavation projects

· Quarry operations

· Mining environments

· Road and infrastructure construction

· Heavy-duty earthmoving work

Quality Control System

From raw material to final packaging, we follow ISO-based inspection flow:

· Material composition verification before casting

· Ultrasonic flaw detection (UT)

· Magnetic particle inspection (MT)

· Dimensional inspection of bolt hole pitch

· Final rotation fit testing 

Packaging and  Delivery

· Anti-rust oil treatment before packing

· Shrink-wrapped protection

· Reinforced wooden export pallet (fumigation-free)

· Standard dispatch: 7–15 days depending on order volume

FAQ

Q1: Does it match original Kobelco SK200-8 drive system?
Yes. Bolt pattern and tooth geometry are CNC-machined according to OEM specifications.

Q2: Why not fully harden the sprocket?
Full hardening increases brittleness. We harden only the teeth to ensure wear resistance while keeping the core impact-resistant.

Q3: Can bulk orders be customized?
Yes. We support OEM marking, packaging, and branding for distributors.
