Excavator Chains

101mm to 260mm Pitch

Our complete range of track chains are available from 101mm pitch to 260mm pitch to suit all types of excavators and other tracked equipment. All excavator chains are grease filled and sealed for extended wear life. Polyurethane seals ensure quiet operation and prevent abrasive materials from entering the internal pin and bush, therefore reducing wear.

Dozer Chains

SALT Chains

For dozer and other demanding applications, we stock a range of quality, heavy duty sealed and lubricated track (SALT) chains which are oil-filled to reduce internal friction between the pin and bushing, therefore extending wear life.

Idlers, Rollers & Sprockets

Undercarriage Components

A comprehensive range of durable idlers, rollers, sprockets and sprocket segments are available from stock to fit most makes and models of excavators, dozers, crushers, screeners and other tracked machinery.

Track Adjusters

Track Tensioning

We also offer a comprehensive range of track adjusters / recoil springs are available from stock for immediate delivery. Maintaining proper track tension is critical for satisfactory track life and track adjusters are designed to absorb shock and maintain correct track tension, thus protecting the idler and minimising undercarriage wear.

Track Shoes & Track Groups

For Dozers & Excavators

A complete range of triple grouser excavator track shoes from 300mm to 1200mm for all standard and LGP applications is held in stock, with non-standard sizes for bespoke applications available on request.

For dozers, we stock a full range of single grouser track shoes in all standards widths from 22” (560mm) to 36” (915mm) to meet every requirement. All dozer track shoes have heavy duty baseplates to increase service life.

We also supply assembled track groups with the chain/track shoe configuration to suit your requirements

Track Guides

For Dozers & Excavators

Track guides are often mistakenly overlooked during routine equipment inspections, but they play a pivotal role in keeping your machinery performing at its peak.

As with every component on a machine, track guides are subject to wear and tear. We encourage our customers to include them in their routine machine inspections to ensure their undercarriage performs at its best.
