Hyundai R220LC-9 Excavator Track Shoe Assembly Forged 23MnB Steel Triple Grouser 190 mm Pitch Undercarriage Track Plate

YT reference YT-R2209-TG800 is an aftermarket track shoe assembly engineered for the Hyundai R220LC-9 hydraulic excavator and the larger R290LC-9 model in the same family. The shoe carries a triple grouser tread with a 190 mm pitch bolt pattern and is drop forged from 23MnB boron steel, a material choice that balances abrasive wear resistance against the toughness needed for impact loading. It is a direct bolt-on replacement for the worn original shoe, so a damaged undercarriage can be rebuilt without changing the links, pins or bushings.

Main Parameters

The models above are just for reference, we can't list all models here. we can supply more products as your requirements. Please feel free to send us your inquiry.

• We purchase the raw materials from famous steel group, ensures the high quality of our track shoes.
• All the track shoes are subject to through hardening processes with spray quenching technique and tempering processes.
• Strict quality control from raw material, design, technology, manufacturing for the entire process of detection.
• We can produce any requested parts according to your blue print or samples.

• Forged 23MnB boron steel: Drop forging compresses the grain flow of the blank, which gives the shoe higher fatigue strength than cast products when the machine works in rock digging and demolition conditions.
• Triple grouser tread: Three parallel bars bite into soft ground, reduce side slip on slopes and make travel direction steadier when the excavator reverses on loose fill.
• Induction hardened surface: The grouser area is hardened by medium frequency induction to 46-52 HRC while the body keeps a ductile core that absorbs sudden shock loads from bucket impacts.
• CNC machined bolt holes: Every hole is drilled and countersunk on CNC equipment so the 190 mm pitch matches the link assembly accurately and the shoe sits flat on the link rails.
• Batch traceability: Heat number, hardness result and dimension records are retained for each production lot, which makes quality tracing simple for dealers and end users.
• Export safe finish: Shoes are anti-rust oiled and painted before packing so they survive long sea voyages to Africa, South America and Southeast Asia without surface corrosion.

*Values are reference; OEM part number confirmation advised before ordering.

Production Process

1. Spectrometric analysis of incoming 23MnB billets verifies the chemical composition of every heat.
2. Billets are heated in a controlled furnace and drop forged into shoe blanks with the triple grouser shape.
3. Blanks are trimmed, punched and straightened to remove flash and correct any distortion.
4. Normalizing followed by quenching and tempering develops a consistent fine-grained structure.
5. Bolt holes are drilled and countersunk on CNC machining centers to the 190 mm pitch layout.
6. Medium frequency induction hardening treats the grouser surface to the target hardness depth.
7. Shot blasting cleans the scale from the surface before final inspection.
8. Hardness, dimensional and magnetic particle checks are performed on sampled pieces.
9. Anti-rust oil is applied and shoes are packed on steel pallets ready for shipment.

Factory Strength

YT is the undercarriage brand of Xiamen Yintai Machinery Co., Ltd., a manufacturer and exporter founded in 2011. The plant runs its own drop forging lines, a CNC machining workshop and heat treatment furnaces, which gives the company direct control over every track shoe batch from billet to finished part. With 50-100 employees and annual export sales of USD 10-20 million, YT supplies track shoes and complete undercarriage components to contractors, dealers and rental fleets around the world.

The factory is certified to ISO 9001:2015 and welcomes third-party inspections such as SGS before shipment. OEM and ODM programs are available for customers that need special shoe widths, private branding or customized export packaging.

• Mining and quarry duty: The hardened triple grouser profile extends service life when the R220LC-9 loads blasted rock and abrasive aggregate all day.
• Complete undercarriage rebuild: We can supply shoes together with links, pins, bushings and rollers so the whole running gear is renewed in one stop.
• OEM style replacement at controlled cost: Parts are made to original geometry, which keeps machines productive without paying brand premiums.
• Fleet stock cooperation: A scheduled supply agreement keeps your warehouse topped up with the most common sizes and lowers emergency purchasing cost.
• Emergency dispatch: Popular widths are kept in stock so a sudden track failure can be solved within days rather than weeks.

These shoes fit Hyundai R220LC-9 and R290LC-9 excavators used in urban excavation, road construction, pipeline laying, aggregate handling and site preparation. The 800 mm width spreads the machine weight and reduces ground pressure on soft job sites, while the triple grouser pattern provides grip for travelling on ramps and muddy terrain.

Precision Inspection Services

Q1: How do I confirm this shoe fits my R220LC-9 or R290LC-9?

Please send your machine serial number, the link pitch and the shoe width, or a photo of the old shoe with a ruler. Our sales team will check the drawing and confirm the correct size before you order.

Q2: Is this an OEM genuine part?

No, this is an aftermarket replacement built to original dimensions and interface geometry. We do not sell genuine OEM parts and we never print OEM part numbers on our products.

Q3: Why is 23MnB steel used and what hardness can I expect?

23MnB boron steel hardens deeply and stays tough after heat treatment. The grouser surface reaches 46-52 HRC while the shoe body remains ductile, which resists both abrasive wear and impact cracking.

Q4: Can I order one sample before a bulk order?

Yes, sample orders from one piece are accepted. After you test the sample on your machine we can move to container quantity with consistent production records.

Q5: What is the delivery time?

Stock sizes ship within 5-7 days. Forged production for special widths usually takes 20-30 days depending on quantity. Air freight is available for urgent breakdowns.

Q6: What warranty do you provide?

We offer 12-18 months warranty against manufacturing defects under normal working conditions. Photos and inspection reports are kept for every batch to support any claim.

Each shoe is rust protected and then strapped on steel pallets with plywood protection, or packed in export wooden crates when required. The quality assurance team checks hardness, pitch and hole position against the drawing, and every shipment can be inspected by SGS or another third party before loading.
