Product Description
Detailed Introduction to Loose Gear Components for Swing & Travel Reducers
I. Product Overview
Our company keeps full sets of loose gear parts for swing reducers and travel reducers of all excavator series in stock. They fit all tonnage excavators of mainstream brands including Sany, CAT, XCMG, Komatsu, Hitachi, Kobelco, V olvo and more. All gear loose parts are machined strictly in accordance with original OEM gear drawings and manufactured from high-strength alloy steel dedicated to construction machinery. The complete set includes separate components such as sun gears, planetary gears, internal ring gears, planet carriers, output shafts, shims, needle rollers and bearings. Damaged parts can be replaced individually instead of replacing the entire reducer assembly, which greatly cuts maintenance costs.
Loose gear parts for regular common models are permanently stocked. Two export packaging options are available: wooden cases or fumigated wooden pallets, with packing and delivery arranged on the same day. Custom production is supported for non-standard gear parts of rare old models and heavy-duty large-tonnage mining excavators. All quotations are negotiable, and bulk container export is available. We provide supporting model comparison tables, dimensional parameters and quality inspection documents, suitable for bulk procurement by repair shops, equipment rental companies and mining projects.
II. Complete Range of Loose Gear Components
1. Loose Gear Parts for Travel Reducers
Sun gears, primary planetary gears, secondary planetary gears, tertiary planetary gears, internal ring gears, planet carriers, drive output shafts, needle roller bearings, isolating shims, retaining circlips, thrust washers, bronze bushings, pressure plates, reduction shaft gears, oil seal retainers.
2. Loose Gear Parts for Swing Reducers
Complete split components including swing sun gears, swing planetary gears, swing internal ring gears, swing planet carriers, swing output gears, central shafts, rollers, wear-resistant shims, locating pins, dust shields and reduction driven gears.
III. Materials & Core Manufacturing Processes
Raw Material Selection
Gear blanks are made of 20CrMnTi / 40CrMo high-strength carburizing alloy steel. Wear-resistant shims and thrust washers adopt high-hardness wear-resistant alloy steel, while load-bearing shafts use quenched and tempered 45# alloy steel. The materials feature excellent impact resistance and fatigue resistance, applicable to high-load intensive operations in mines and rockwork sites.
Precision Machining Flow
Precision turning by CNC lathe → Precision hobbing / gear shaping → High-temperature carburizing heat treatment → High-frequency quenching of gear surfaces → Low-temperature tempering to eliminate internal stress → Precision gear grinding → Dynamic balance testing → Full dimensional inspection.
Process Advantages
The gear surface boasts an even hardened layer with hardness reaching HRC58–62. Gear roots have sufficient toughness to resist tooth breakage. Gear fitting tolerances strictly comply with OEM standards, delivering uniform meshing clearance, quiet operation, low risk of gear tooth breakage and low heat generation.
IV. Applicable Equipment Models
Covers all tonnages of mini excavators, medium earthmoving excavators and heavy mining excavators.
V. Core Product Advantages
Separate Sales of Split Loose Components
There is no need to purchase complete reducer assemblies. Only the damaged gear component needs to be replaced, which drastically reduces spending on maintenance consumables and shortens equipment downtime.
OEM-Grade Meshing Precision
The tooth profile, module, pressure angle and mounting hole diameter fully match OEM specifications. After installation, gears mesh smoothly without vibration or abnormal noise, preventing rapid secondary abrasion.
High Strength, Durability & Impact Resistance
Adopting professional carburizing and quenching technology, the gear surfaces are wear-resistant and gear roots resist fracture. The service life far exceeds that of ordinary low-quality copied gears under long-term heavy mining working conditions.
Full Coverage of All Brands & Tonnages
Mass stock of common loose gear parts for mainstream brands. One-stop supply of all split gear components for swing and travel reducers without sourcing goods from multiple suppliers.
Comprehensive Export Support
We provide real dimensional photos of parts, model compatibility lists, hardness test reports and complete customs clearance & commodity inspection documents to support global sea freight export.
VI. Commercial Service Terms
Loose gear parts for swing and travel reducers of mainstream models are sufficiently in stock, accepting single-piece retail and bulk wholesale orders for repair workshops. Custom production is available for scarce outdated models.
Packaging options include thickened solid wooden cases and fumigated wooden pallets with internal foam buffer protection for shockproof and rustproof performance, suitable for long-distance transportation via land and sea containers.
All quotations are negotiable, with tiered volume discounts for large orders.
Every gear is inspected for outer diameter, tooth profile, hardness and flatness before shipment. After-sales exchange is supported for mismatched component models, together with basic warranty coverage.
