Kobelco Excavator Double Grouser Track Shoe Assembly Forged 25MnB Steel 190mm

The SK200-8 track shoe assembly is a soft-ground oriented undercarriage part produced for Kobelco SK200-8 and SK260LC-8 excavators. Many Kobelco units of this size work in paddy drainage, pipeline laying, wetland reclamation and municipal jobs where the ground is loose, moist or easily rutted, and a conventional triple bar shoe tends to sink or clog in those conditions.

YT answers that operating profile with a forged double grouser shoe in 25MnB manganese boron steel, arranged on a 190 mm pitch with a wide pad that lowers ground pressure and improves flotation. The design keeps the proven bolt pattern of the original shoe so it fits the standard Kobelco chain without adapters, while the two broader bars provide a self cleaning footprint that sheds mud as the track rotates.

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.

• Double grouser footprint: Two wide bars distribute the machine load over a larger contact area, cutting sinkage in soft and recently filled ground.
• 25MnB forged material: The higher manganese content in this boron grade adds toughness for jobs where the shoe bends over uneven, boggy terrain.
• Self cleaning action: The open center channel between the bars releases clay and mud on every track revolution, keeping the grousers effective.
• Smoother travel response: With fewer, wider bars the shoe rolls over hard patches with less vibration, easing the load on rollers and final drives.
• 190 mm pitch precision: Drilled hole centers follow the Kobelco pitch standard so chain engagement stays even and quiet in both directions.
• Anti-rust finish: A primer coat protects the steel from pitting during storage and ocean shipment in humid climates.

Listed values are reference data collected from standard YT production lots for this Kobelco shoe type. Because undercarriage configurations vary by region and carriage option, confirm the pitch, width and link count of your machine chain before you order.

Production Process

1. Steel verification: each batch of 25MnB bar is spectro tested on arrival and the chemistry is recorded against the heat number.
2. Cutting and heating: bars are cut to blank length and heated evenly in a walking beam furnace ahead of forging.
3. Die forging: the blank is formed in closed dies to produce the double grouser profile and machinable bolt pads.
4. Normalizing treatment: forgings are normalized to create a uniform, fine grained microstructure.
5. Quenching and tempering: the body is heat treated to develop the toughness needed for flexing over soft ground.
6. CNC hole machining: pitch holes and bolt counterbores are drilled and finished on CNC equipment.
7. Induction hardening: grouser bar surfaces are hardened and tempered to the wear resistant hardness band.
8. Quality inspection: dimensional gauging, hardness testing and visual checks are completed on every lot.
9. Protection and packing: shoes are primed, stacked with spacers and strapped onto pallets for export.

Factory Strength

XIAMEN YINTAI MACHINERY CO., LTD. is an undercarriage specialist that has supplied forged track components under the YT brand since 2011. With a workforce of 50-100 people and export sales accounting for about 90-100 percent of its USD 10-20 million annual revenue, the company serves aftermarket distributors, equipment dealers and construction contractors in more than twenty countries.

YT maintains complete in-house capability for this product line: die design, hot forging, normalizing and quench-temper furnaces, CNC machining, induction hardening and final assembly. Quality control follows the ISO 9001:2015 framework with incoming material inspection, in-process patrol checks and final batch release records. Third-party inspection such as SGS can be organized at the buyer request, and OEM/ODM services cover private labeling and custom shoe specifications.

• Soft ground and swamp work: The double grouser shoe keeps dredging, paddy and reclamation machines moving where standard shoes lose traction or sink into the working surface.
• Pipeline and utility trenches: On utility jobs that cross farmland and yards, the lower ground pressure reduces damage to finished surfaces and speeds site restoration.
• Fleet conversion programs: Contractors switching machines between dry and wet sites can store a second set of double grouser shoes and swap them to match the season.
• Cost effective aftermarket supply: YT offers dependable Kobelco replacement shoes at a competitive price point with documented material quality for procurement teams.
• Mixed fleet ordering: Combine SK series shoes with other YT undercarriage items in one container to cut freight cost per part and simplify supplier management.

This track shoe assembly is at home on Kobelco 20 to 26 ton excavators working in soft soil conditions: canal dredging, pipeline right-of-way, foundation work on compressible soils, swamp clearing, agricultural land development and general utility construction. The double grouser configuration also suits machines that travel long distances between scattered job sites, where reduced vibration and better flotation protect both the operator and the running gear.

Precision Inspection Services

Q1: Why choose a double grouser shoe instead of a triple grouser type?

Double grouser shoes have wider, fewer bars that spread load better on soft ground and clear mud more easily. If your Kobelco machine mainly works firm or rocky ground, a triple grouser shoe may be the better choice, and YT can supply both styles.

Q2: Does this shoe fit my SK260LC-8?

The SK260LC-8 commonly runs in the same pitch family, but the track frame is longer and the standard shoe width may differ. Please measure your existing shoe and confirm the link count before ordering.

Q3: What is the difference between 23MnB and 25MnB steel?

Both are boron alloyed forging steels. The 25MnB grade carries slightly higher manganese, which improves hardenability and toughness and suits shoes that must flex over uneven soft ground without cracking.

Q4: Do you offer samples for evaluation?

Yes, sample orders from one piece are welcome. Samples of stock sizes leave the factory within 5-7 days and the sample amount is deductible from the first bulk order.

Q5: What are the payment and delivery conditions?

We accept T/T and L/C. Production orders are normally completed in 20-30 days after deposit, and the product carries a 12-18 month warranty against material and workmanship defects.

Shoes are treated with anti-rust primer, layered with timber spacers and strapped to steel pallets that withstand forklift handling and container stacking. The packing list, material certificate and hardness report accompany each shipment, giving the importer full documentation for customs and for their own quality records. YT invites buyers to arrange pre-shipment inspection and keeps batch samples for at least twelve months after delivery.
