High Light SK250LC-6 Top Roller OEMHigh-Grade Steel Heat Treated RollerKobelco Factory OEM Carrier Roller
SK250LC-6 SK250LC-8 Top Roller OEM Replacement 24100N5946F2, Carrier Roller for Excavator Undercarriage
Product Overview

This heavy-duty carrier top roller is a 1:1 OEM direct replacement for SK250LC-6 and SK250LC-8 long track excavators, with standard OEM part number LQ000210. Perfectly matching original mounting dimensions and bolt holes, it requires no cutting, drilling or any on-site modification. It effectively supports track operation, avoids track sagging and vibration, and optimizes undercarriage running performance for long-working heavy-duty excavator fleets.

Specifications
Item Specification
OEM Part Number 24100N5946F2
Applicable Excavator Model SK250LC-6 / SK250LC-8
Machining Tolerance ±0.01mm CNC ultra-precision machining
Heat Treatment Process Overall quenching + stress relief tempering
Applicable Working Scenarios Muddy construction site, gravel quarry, road renovation, heavy-load earthmoving terrain
Installation Type Plug-and-play OEM direct replacement
Applicable Working Environments

SK250LC-6 and SK250LC-8 long track excavators are widely used in large-scale earthmoving projects, quarry mining, road reconstruction and complex muddy working sites. Continuous gravel friction, long-term water immersion and frequent impact bring high load pressure to undercarriage parts. This top roller is professionally built to adapt to harsh working conditions and maintain stable performance during prolonged operation.

Core Production & Heat Treatment Process

Adopt high-strength one-piece forging steel blank to withstand heavy operational loads. Dual standard heat treatment is adopted: integral quenching improves surface hardness for excellent abrasion resistance; tempering eliminates internal metal residual stress to enhance structural toughness. All mounting holes and matching surfaces are processed by high-precision CNC equipment, with machining tolerance strictly controlled within 0.01mm, fully consistent with original factory OEM standards.

On-site Installation Steps
  1. Raise the excavator track with a hydraulic jack to separate track from ground and release partial track tension
  2. Remove fixing bolts of the old top roller, take out damaged roller and clean dust and sediment on the mounting base
  3. Place the new top roller in original position, align reserved bolt holes accurately
  4. Lock all fixing bolts with standard torque, reset track tension and conduct track idle running test
  5. Check no abnormal vibration or friction noise to complete installation
Product Advantages
  • High-precision size matching stabilizes track running and reduces walking vibration
  • Reinforced floating seal structure effectively isolates dust and muddy water
  • Complete dual heat treatment upgrades durability for heavy-duty working sites
  • Reinforced structure suits high-load operation of long track chassis
  • Direct bolt-on installation saves maintenance time and labor cost
Customer Application Case

A large engineering fleet operates multiple SK250LC-6 and SK250LC-8 excavators for quarry and infrastructure projects. After equipped with our OEM-spec top rollers, all undercarriage parts keep stable operation over 1800 working hours with excellent sealing condition and complete roller shell, cutting annual undercarriage maintenance cost by 33%.

Frequently Asked Questions
Q1: Does this top roller fit SK250LC-6 and SK250LC-8?
A: Yes, OEM part number 24100N5946F2 is fully compatible with both models, no extra adjustment needed.
Q2: What are the advantages of our products over ordinary aftermarket rollers?
A: Our products adopt complete dual heat treatment and 0.01mm high-precision machining, delivering better abrasion resistance and structural stability for long-term heavy-duty work.
Q3: Can you provide batch quality inspection reports for bulk orders?
A: Yes, we can provide professional heat treatment reports and dimensional inspection reports to support customer quality inspection and customs clearance.
