Heavy Duty 25MnB Steel Track Shoe Assembly Forging and Casting Track Pad for EX200 Excavator

This EX200 track shoe assembly is a precision-engineered undercarriage component manufactured by YT, a specialized factory with more than 35 years of experience in excavator and bulldozer spare parts production. Designed as a direct replacement for the EX200 undercarriage system, it is built from 25MnB Steel steel and finished with a controlled heat treatment that delivers a surface hardness of HRC 40-55. Every unit is produced on modern machining centers and vertical CNC lathes so that critical dimensions, run-out and tooth geometry stay within strict tolerances.

The component is intended for machine owners, repair workshops and spare parts distributors who need reliable aftermarket undercarriage parts that reduce downtime and lower the total cost of ownership. With a monthly supply capacity of 10,000 pieces, we support both small trial orders and long-term, container-level contracts.

• Wear-Resistant Grouser Plate: Forged and cast 25MnB Steel steel with a controlled heat treatment reaching HRC 40-55 for stable performance in abrasive soil and rock.
• Stable Load Distribution: Uniform grouser spacing and thickness control ground pressure, improving traction and machine stability on soft and uneven terrain.
• Impact-Tough Body: A ductile core absorbs shock loads from repeated contact with rocks, frozen ground and construction debris.
• Accurate Bolt Pattern: Bolt holes are drilled and reamed to OEM pitch so the shoe bolts onto the chain link without modification.
• Anti-Corrosion Coating: Protective finish resists rust during shipping and outdoor storage, keeping the plate ready for immediate installation.
• Wide Model Coverage: Suitable for Komatsu, Caterpillar, Hitachi, Kobelco and Doosan crawler machines, with standard and widened grouser options.

Production follows a documented seven-stage route. Each track shoe assembly starts from verified raw stock, is shaped by casting or forging, then rough- and finish-machined before receiving its hardening treatment. A final inspection gate checks hardness, dimensions and surface integrity before packing, so that every batch behaves predictably in the field.

1. Raw material inspection and光谱 verification of the steel chemistry
2. Modeling, pattern making and sand preparation for casting or billet cutting for forging
3. Casting or forging into a near-net shape, followed by controlled cooling
4. Normalizing and rough machining to remove scale and establish reference surfaces
5. Finish machining of teeth, bores, bolt holes and pitch on CNC lathes and machining centers
6. Induction hardening and quench-tempering to the specified surface hardness
7. Dimensional inspection, magnetic particle crack testing and surface treatment

YT is a dedicated manufacturer of excavator and bulldozer undercarriage parts with over 35 years of production experience. Our plant operates casting, forging, heat treatment and precision machining lines under one roof, supported by an in-house metallurgical laboratory and a trained quality team. We export to North America, Europe, the Middle East and Southeast Asia, and we regularly produce custom parts from OEM drawings and samples. Flexible payment terms, video technical support and 24-hour online service are standard for our partners.

We help customers match the right track shoe assembly to their working conditions. For high-abrasion sites we recommend the hardened specification; for machines that work mainly on soft ground we can supply a standard plate to balance wear life with cost. Combine this part with our track chains, rollers, idlers and idler assemblies for a complete undercarriage rebuild from a single supplier.

• Undercarriage refurbishment programs for EX200 contractors and rental fleets
• Spare parts distribution for dealers who serve multiple excavator and bulldozer brands
• Wear-part replacement for mining, quarry, forestry and construction equipment
• Custom batches matched to OEM samples for machines with discontinued factory parts

• Does this track shoe fit my machine? It is produced for the listed model and matched to the OEM bolt pitch, so it fits directly without drilling or modification.
• What material and hardness do you use? We use 25MnB steel with a controlled heat treatment reaching HRC 40-55, balancing wear resistance and toughness.
• Can you supply custom widths or grouser heights? Yes. We produce standard and widened plates and can follow customer drawings or samples.
• What is the delivery time? Normally 7 to 30 days after order confirmation, depending on quantity and stock.
• How is the product packed? Anti-rust protected, then packed in wooden cases or pallets secured for ocean freight.

Parts are protected with anti-rust oil or coating, packed in strong wooden cases or pallets and secured for ocean freight. Neutral or customer-branded packing is available. We offer a warranty of 12 to 18 months against manufacturing defects and provide video technical support for installation. Delivery is normally 7 to 30 days after order confirmation, depending on quantity and stock.
