Komatsu PC210-8 Excavator Triple Grouser Track Shoe Assembly Forged 23MnB Steel

The PC210-8 track shoe assembly is an undercarriage wear part engineered for Komatsu PC210-8 and PC220-8 excavators, two of the most widely deployed 20-ton class machines in earthmoving fleets around the world. As the component that transfers digging thrust from the track chain into the ground, the shoe directly influences traction, machine stability and hourly operating cost on every job site.

Each shoe in this range is hot-forged from 23MnB boron alloy steel, machined to a 190 mm pitch configuration and offered in an 800 mm triple grouser layout that suits general excavation, trenching and heavy loading cycles. The product is built as a direct replacement for the original track shoe profile, allowing maintenance teams to restore a worn undercarriage without modifying the chain, sprocket or idler geometry of the machine.

Our Advantages

• 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 steel: Hot forging refines the internal grain structure of the boron alloy, delivering a balanced combination of wear resistance and impact toughness for rocky excavation sites.
• Triple grouser profile: Three traction bars bite firmly into the ground and provide stable flotation, reducing slip on graded slopes and hard-packed surfaces during bucket breakout.
• 190 mm pitch accuracy: Pitch holes are CNC positioned inside tight tolerances so each shoe aligns cleanly with the chain bushings and bolts seat without bending stress.
• Induction hardened surfaces: Grouser tops and bolt bosses are selectively hardened to resist abrasive wear while the shoe body keeps enough ductility to absorb shock loads.
• Corrosion protection: Every shoe receives anti-rust primer before packing, protecting machined faces during ocean freight and open-air yard storage.
• Matched fastener option: Shoes can be supplied as complete sets together with grade 10.9 bolts, nuts and washers for one-stop undercarriage replacement.

The table below lists the main dimensional and material data of this track shoe. Figures are reference values measured on standard production batches; always confirm the pitch, width and link arrangement of the chain fitted to your machine before ordering.

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

1. Raw material incoming inspection: spectrometric analysis verifies the 23MnB chemistry of every heat of steel bar before release to the forging shop.
2. Heating and hot forging: billets are induction heated to forging temperature and formed in closed dies to create the shoe blank with grouser geometry.
3. Trimming and normalizing: forging flash is trimmed and blanks are normalized to refine the grain and relieve internal stress.
4. Quenching and tempering: heat treatment sets the core hardness and toughness to the specified range for impact resistance.
5. CNC machining: pitch holes, bolt holes and locating faces are drilled and milled on CNC lines for repeatable accuracy.
6. Induction surface hardening: grouser working surfaces are induction hardened and tempered to reach the 48-53 HRC band.
7. Dimensional and hardness inspection: shoes are checked for flatness, hole pitch and surface hardness with calibrated gauges.
8. Anti-rust treatment: machined parts are cleaned, coated with anti-rust primer and dried before packing.
9. Final packing: shoes are bundled on steel pallets with protective wrapping together with shipping documentation.

XIAMEN YINTAI MACHINERY CO., LTD. (YT brand) has manufactured undercarriage components since 2011 and today operates an integrated production base covering die forging, CNC machining, heat treatment and final assembly for excavator and bulldozer running gear. The company employs 50-100 people and directs roughly 90-100 percent of its output to export markets, with annual sales in the USD 10-20 million range.

In-house forging presses, heat treatment furnaces and induction hardening stations give YT direct control over the hardness and toughness of every track shoe, while the ISO 9001:2015 quality system governs inspection at each process gate. Customers may arrange SGS or third-party inspection before shipment, and the engineering team supports OEM/ODM programs from drawing review through pilot production.

• High-wear mining and quarry sites: Where abrasive rock shortens shoe life, the hardened triple grouser profile and boron steel body extend service intervals compared with ordinary carbon steel shoes.
• Rebuild programs for aging machines: Owners refreshing a mid-life PC210-8 or PC220-8 can pair these shoes with new chains and rollers to restore the whole running gear in one campaign.
• OEM replacement cost control: YT shoes give fleets a dependable alternative to original parts at a lower unit cost, with the same dimensional philosophy for direct bolt-on fitment.
• Fleet-scale supply contracts: For contractors running multiple Komatsu machines, scheduled batch supply keeps consistent hardness and heat numbers across every set delivered.
• Emergency downtime refill: Popular sizes are kept in stock so a single damaged shoe can be dispatched quickly to get the excavator back to work without waiting for a full set.

These triple grouser shoes are suited to general earthmoving, road construction, quarry loading, pipeline trenching and site leveling where Komatsu 20-ton class excavators operate on firm or mixed ground. The 800 mm width spreads machine weight to limit ground pressure on semi-compacted fill, while the grouser bars hold grip during heavy bucket penetration. For soft terrain or swampy conditions, YT also offers double grouser and flat pad options in the same pitch family.

Q1: How do I confirm that this shoe fits my Komatsu machine?

Check the pitch and width of one shoe removed from your chain, count the links per side, and compare the bolt hole spacing with the table above. Sending a photo of the old shoe and the machine serial number to our sales team is the fastest way to get a confirmed recommendation.

Q2: Is this an OEM part or an aftermarket replacement?

YT manufactures aftermarket undercarriage parts with our own part numbering. The shoe is dimensionally designed as a replacement for the original Komatsu profile, so it mounts directly on the standard chain without modification.

Q3: What hardness and service life can I expect?

The working surface is induction hardened to roughly 48-53 HRC. Actual life depends on ground conditions, operator habits and maintenance, but the forged 23MnB material is selected to give a long, predictable wear window in typical excavation duty.

Q4: Can I order samples before a bulk purchase?

Yes. Sample orders are accepted starting from one piece, and the sample price can be credited against a later bulk order. Lead time for a sample is normally 5-7 days when the size is in stock.

Q5: What are the delivery terms and warranty?

Stock sizes ship in 5-7 days and production orders in 20-30 days. Payment is by T/T or L/C, and the shoes carry a 12-18 month warranty against material and workmanship defects under normal operating conditions.

Each shoe is coated with anti-rust primer, separated with wooden spacers and strapped securely onto steel export pallets to prevent movement in transit. Every production batch is released with a mill test certificate covering the material heat number and hardness test results, and the cartons are marked with part number, quantity and pallet weight for easy customs clearance and warehouse receiving.
