Installation Type
Plug-and-play OEM direct replacement
Applicable Working Environments
SK200 series 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
Raise the excavator track with a hydraulic jack to separate track from ground and release partial track tension
Remove fixing bolts of the old top roller, take out damaged roller and clean dust and sediment on the mounting base
Place the new top roller in original position, align reserved bolt holes accurately
Lock all fixing bolts with standard torque, reset track tension and conduct track idle running test
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
Universal design fits four mainstream SK200 models to simplify parts stocking
Direct bolt-on installation saves maintenance time and labor cost
Customer Application Case
A large engineering fleet operates multiple SK200-3, SK200-5, SK200-6 and SK200-8 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%.
