Technical details and manufacturing context for Track Assembly (Track Chain)
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Track Pitch | 101.6–260 mm | Standard pitches for excavators and dozersISO 22643 |
| Track Width | 203–915 mm | Width affects ground pressure and flotation |
| Number of Links | 30–90 links | Determines total track length |
| Tensile Strength | 150–350 kN | Must match machine weight and pulling forceISO 22643 |
| Hardness (Pin/Bushing) | HRC 45–55 HRC | Higher hardness improves wear resistanceISO 22643 |
| Material Grade | 35MnB–40MnB | Boron steel for hardenabilityGB/T 3077 |
| Operating Temperature | -40–80 °C | Seals and lubricants degrade outside range |
| Weight per Meter | 50–250 kg/m | Affects transport and installation |
| Bushing Outer Diameter | 40–120 mm | Matches sprocket and idler geometryISO 22643 |
| Pin Diameter | 20–70 mm | Determines shear strengthISO 22643 |
| Track Gauge | 1200–3000 mm | Distance between track centers |
| Seal Type | Metal face seal | Prevents ingress of dirt and moistureISO 2982 |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory, track chains are typically made from alloy steel or manganese steel. These materials provide the necessary strength and wear resistance for heavy-duty applications.
The track pitch for excavators and dozers typically ranges from 101.6 mm to 260 mm, as referenced in ISO 22643. However, the exact pitch must be confirmed for the specific machine model.
Track width affects ground pressure and flotation. Wider tracks distribute the machine's weight over a larger area, reducing ground pressure and improving flotation on soft or uneven terrain. The directory lists a reference range of 203–915 mm.
Relevant standards include ISO 22643 for track pitch, tensile strength, hardness, bushing outer diameter, and pin diameter; GB/T 3077 for material grade; and ISO 2982 for seal type. These standards serve as procurement references and must be verified with the manufacturer.
