Description
ZX200-5G Top Roller OEM Replacement 9262248
This carrier top roller is a 1:1 OEM direct replacement for ZX200-5G excavator, matched with official part number 9262248. It perfectly fits original mounting holes and assembly dimensions without cutting, drilling or any on-site secondary modification.
Item Specification
OEM Part Number 9262248
Applicable Excavator Model ZX200-5G
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, rough earthmoving terrain, high-frequency urban construction
Installation Type Plug-and-play OEM direct replacement
Applicable Working Environments
ZX200-5G new-generation excavators are widely used in high-frequency urban construction, large-scale earthmoving, quarry mining and complex muddy working sites. This upgraded heavy-duty top roller is customized to match the high-load working characteristics of ZX200-5G machines.
Core Production & Heat Treatment Process
Adopt high-strength one-piece integrated forging steel blank to meet higher load demand of 5G series excavators. Dual standard heat treatment is adopted: integral quenching improves surface hardness to resist long-term abrasive wear from gravel and sediment; secondary tempering eliminates internal metal stress, avoiding roller shell cracking under frequent strong impact.
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.
Optimized Operation Advantages
  • Accurate OEM size matching eliminates track deviation and walking vibration during high-frequency operation
  • Enhanced heavy-duty floating seal prevents muddy water and dust intrusion, avoiding oil leakage in harsh sites
  • Upgraded overall structural toughness adapts to frequent impact loads of 5G generation excavators
  • Direct bolt-on installation saves maintenance time and reduces on-site labor costs
Real Customer Cooperation Case
A Southeast Asian engineering fleet equipped with batches of ZX200-5G excavators used generic top rollers before, which failed within 720-850 working hours due to insufficient heat treatment. After replacing with our OEM-standard top rollers, all parts run stably over 1800 working hours without seal leakage or shell fracture, cutting annual undercarriage maintenance cost by 34%.
Frequently Asked Questions
Q1: Is this top roller fully compatible with ZX200-5G?
A: Yes, OEM part number 9262248 is specially customized for ZX200-5G, 100% consistent with original installation size, no extra adjustment required.
Q2: What is the difference between this roller and ordinary ZX200 standard roller?
A: This model is upgraded for 5G high-load version with thicker roller shell and better impact resistance. Ordinary standard rollers cannot bear long-time high-frequency impact and are easy to crack.
Q3: Can you provide batch quality inspection reports?
A: Yes, we can provide complete heat treatment test reports and dimensional inspection reports to support customers' bulk order quality inspection.
