A critical undercarriage component – a brand new 49-link track chain by NEXGEN. This is a SALT (Sealed and Lubricated Track) chain, where pins and bushings are hermetically sealed, drastically extending undercarriage life by minimizing internal friction. Designed for 18-26 ton class excavators, including JCB JS200-JS260 and CAT 320-325 series. Induction-hardened links, pins, and bushings guarantee maximum resistance to wear and stretching.
NEXGEN is a leading supplier of undercarriage components. By choosing this brand, you invest in precision-made links, hardened pins, and durable bushings, which translates to reduced friction, longer service life, and lower operating costs.

The list above is for reference. It is crucial to match the link count (49) and pitch (190 mm).
Working on track undercarriages is extremely dangerous. Use extreme caution when splitting and joining the chain. Release track tension via the grease adjuster before starting work. The grease in the tensioner is under immense pressure and its sudden release can cause severe injury.
The track chain is the assembly of links, pins, and bushings that creates the "road" for the machine and transfers drive power from the sprocket to the ground. It is the primary component of the undercarriage, and its wear affects all other components.

A SALT chain has special seals that trap grease inside each pin and bushing. This prevents internal friction ("pin-in-bushing" wear), which is the main cause of chain "stretching". Lubricated chains have a much longer service life than dry chains.
2. What is "Pitch 190 mm"?Pitch is the key dimension of a track chain. It is the distance measured from the center of one pin to the center of the next pin in the link. This value (190 mm) must be identical to the sprocket and chain to mesh correctly.
3. My chain has 48 links. Will this 49-link chain fit?No. The link count must be an exact match for your machine's specification. A chain with a different link count will not fit the undercarriage. This model has 49 links. Always count the links on your old chain before ordering.
