Description

Excavator Hydraulic Motor 1st & 2nd Stage for SK200-8 Swing Reduction Gearbox

Restore smooth and powerful swing operation to your Kobelco excavator with this premium 1st and 2nd stage swing carrier assembly, engineered as a direct OEM replacement for the Kobelco SK200-8 swing reduction gearbox. As the core load-bearing component of the swing drive system, this assembly transmits torque from the swing motor to the excavator superstructure, enabling precise 360° rotation. Manufactured to exact factory specifications, it resolves common swing system issues including weak rotation, abnormal noise, and gear slippage. Each assembly comes fully pre-assembled with all planetary gears and bearings, eliminating the need for separate component sourcing and reducing installation time by up to 60%.

Core Selling Points

✅ Perfect OEM Fit for Kobelco SK200-8
Precision-machined to match the exact dimensions, tooth profiles, and mounting points of the original Kobelco swing carrier. It bolts directly into the existing swing reduction gearbox without any modifications, ensuring seamless integration and minimal equipment downtime.
✅ Industrial-Grade Heavy-Duty Construction
Manufactured from high-strength alloy steel with advanced carburizing and quenching heat treatment. This provides exceptional hardness, wear resistance, and impact strength, extending service life by 2-3 times compared to standard aftermarket alternatives.
✅ Precision-Engineered for Smooth Operation
All gears are hobbed and ground to AGMA Class 8 precision standards, ensuring perfect meshing, minimal backlash, and quiet operation. This eliminates vibration and reduces stress on other swing system components.
✅ Complete Ready-to-Install Assembly
Each unit comes fully assembled with 1st and 2nd stage planetary carriers, sun gears, planet gears, and needle bearings. It is 100% load-tested before shipment to guarantee reliable performance under heavy working conditions.
