Sealed-and-lubricated (SALT) chains: the pin-and-bushing wear surfaces are factory-lubricated and sealed with O-rings or seal-kits. Lubrication retained inside the chain throughout its operating life. Significantly longer wear life than standard chains (typical 50-100% extension). Modern plant equipment standard. Standard (greased) chains: pin-and-bushing surfaces are greased at assembly but not sealed. Lubricant gradually washes out during operation. Used on older equipment and in some specific applications. SALT chains cost more initially but the longer service life makes them more economical for trade-and-fleet use.

Three matches: (1) chain pitch — the distance between pin centres, must match the equipment's sprocket tooth pitch (e.g., 154mm pitch chain matches 154mm pitch sprocket); (2) link count — the number of pin links in the complete chain, sized to match the equipment's track-frame and tension-adjustment range; (3) shoe-mounting bolt pattern (for bare chains where shoes are fitted separately). The OEM part number is the most reliable match. WhatsApp 07754288583 with the equipment make, model, and original chain specification for cross-reference.

Track-chain service life depends on equipment type, operating conditions, and chain construction. Typical service hours before chain replacement: SALT chains in standard plant operation 4,000-8,000 hours; standard chains 2,000-4,000 hours; in abrasive or high-impact conditions (rocky terrain, demolition, mining) 50-70% of normal life. Symptoms of chain wear approaching replacement: chain elongation past adjustment range (idler can no longer be moved forward enough to maintain track tension); visible pin-bushing wear; chain skipping on the sprocket under load.

Yes. Replacement shoe-mounting bolts (for bare chains where shoes are bolted to the chain — must match the OEM specification for grade and torque rating), replacement track-chain master pins (the connecting pin at the chain join, removable for chain installation and removal), chain-pin removal and installation tools (specialist hydraulic tools for pressing pins in and out without damage), and matched seal kits for SALT chain rebuild are available alongside the track-chain range. WhatsApp 07754288583 for advice.

Every product is backed by our Fit Guarantee. If a part is incompatible with your machine, you can return it hassle-free. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will arrange collection. For other returns, email us first to obtain a Return Merchandise Number before sending. Returns are accepted within 30 days of purchase, in original packaging, on UK orders. A restocking fee may apply on returns where the buyer has changed their mind. Refunds are issued to the original payment method once the return is inspected.

Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and "Check where we deliver" confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa.

Track Chain

FilterFilters
View as Grid List

Within Under Carriage, Track Chain covers the steel track chains fitted to plant tracked-equipment undercarriages — the assembled chain of track shoes, pin links, bushings, and connecting hardware that wraps around the sprocket and idler to provide the running surface and traction. Track chains include both bare track-chains (for use with separate track shoes) and complete track-chain assemblies (with shoes installed).

Parts for Machines supplies track chains across the plant aftermarket — covering chains for the major plant equipment ranges, sized to match specific equipment final-drive sprocket and idler geometries.

Product pages list the equipment make and model the chain is approved for, the chain type (bare chain or shoe-assembled), the chain pitch (the distance between adjacent pin centres — must match the equipment's sprocket tooth pitch and idler diameter), the pin-and-bushing specification (diameter, length, hardness rating), the link count (the number of pin links in the complete chain — must match the equipment's track-frame length and tension-adjustment range), the construction (sealed-and-lubricated for modern equipment; standard for older equipment), the rated load capacity, and the OEM cross-reference.

For replacement of an existing track chain, the OEM part number is the most reliable match. Where the OEM number isn't available, identify by the equipment make, model, year, and the chain's measured pitch and link count. Always replace track-chains as part of a matched undercarriage rebuild — sprockets, chains, idlers, and rollers worn together must be replaced together. Track-chain elongation should be measured periodically across the chain length — when elongation exhausts the idler tension-adjustment range and the track cannot be properly tensioned, the chain has reached its replacement point. Trade pricing on multi-chain and fleet orders is available; contact the team via WhatsApp 07754288583.
