EC460 Travel Gearbox 3rd Planetary Carrier Spider With Sun Gear Assy for Excavator Parts SA8230-35750 SA8230-35560

This third-stage planetary carrier spider assembled with sun gear serves as the vital medium-speed power transmission component fitted within the travel reduction gearbox of EC460 crawler excavators. During all-terrain traveling and heavy digging operations at mines, earthmoving sites and infrastructure projects, this assembly undertakes continuous torque transfer and frequent impact loads, delivering consistent power distribution for the excavator’s travel system.

All manufacturing standards strictly comply with OEM dimensional tolerances. Gear tooth profiles, spline parameters and mounting datum dimensions fully match the cross-reference part numbers SA8230-35750 and SA8230-35560. Direct installation without secondary cutting or grinding greatly reduces on-site repair labor hours and shortens equipment downtime caused by long lead times of original genuine components.

EC460

1. Dual Cross-Reference Part Numbers, Exclusive Fit for EC460

   SA8230-35750 and SA8230-35560 own interchangeable installation dimensions. This planetary carrier assembly is specially engineered for EC460 travel gearbox structure and cannot adapt to other excavator models. Strict replication of OEM geometric parameters avoids assembly clearance deviation, walking vibration and accelerated gear wear after replacement.

2. Integrated Forging Structure Suited for Continuous Heavy-Duty Operation

   Conventional low-grade planetary carrier assemblies are prone to spider cracking and gear tooth breakage under prolonged rough-terrain operation. Our product adopts one-piece precision forging and overall heat treatment technology, significantly enhancing impact resistance. It maintains stable service life under round-the-clock heavy excavation and frequent traveling workloads.

3. Independent Dual Pre-Delivery Testing Eliminates Hidden Risks

   Every finished assembly undergoes two separate testing sessions before leaving the factory. Dimension calibration confirms all fitting tolerances; simulated travel fatigue testing replicates harsh quarry working conditions to verify transmission stability. Defective goods are screened out in advance to avoid unexpected equipment shutdown losses for repair yards and mining contractors.

4. Cost-Effective Solution for Excavator Fleets & Repair Workshops

   Genuine planetary drive spare parts come with high purchase prices and unstable supply cycles. This aftermarket assembly provides equivalent load capacity and service cycle matching original parts at competitive factory prices, effectively lowering recurring maintenance costs for machinery leasing companies and repair shops running EC460 equipment.

5. Flexible Global Logistics Solutions for Overseas Buyers

   All stocked goods can be dispatched within 3 working days after payment confirmation. Air freight supports urgent breakdown orders for remote construction sites. Consolidated sea freight and full-container transport offer economical bulk delivery solutions for spare parts distributors serving Africa, Southeast Asia, the Middle East and Latin American markets.

Our factory possesses more than 10 years of specialized R&D and mass-production experience in excavator final drive planetary components. Travel gearbox spare parts constitute our mature core product line. We operate a closed-loop production workflow covering alloy steel forging, precision gear machining, integral heat treatment and finished product load simulation testing. Professional heavy-load test benches simulate severe quarry and foundation construction environments to continuously optimize component shock resistance and long-term durability. Our planetary gear spare parts are exported to dozens of countries annually, maintaining stable long-term cooperation and consistent positive feedback from global heavy machinery spare parts suppliers.
