Steel tracks are the running gear of tracked plant: the linked steel chains and shoes that carry excavators, dozers and tracked loaders across ground that would destroy tyres. PartsForMachines supplies steel track and track group assemblies to UK plant operators, contractors and repairers, matched by machine make and model across the common excavator and dozer classes, with the supporting undercarriage — bottom rollers, carrier rollers, idlers, sprockets, track adjusters and track guides — listed in the same section.
Steel track sells by machine fitment, and the page-level data covers what a fitter needs to confirm it: link count, pitch, shoe width and shoe style (triple grouser for general excavation, flat or rubber-padded shoes where surfaces matter). Track group assemblies come complete with shoes fitted; chains and shoes are also available separately where only one element is worn. Because undercarriage wears as a system, the matching rollers, idlers and sprockets are listed alongside — fitting new track over a worn sprocket shortens the life of both.
Wear measurement decides timing: link pitch stretch, shoe grouser height and roller tread thickness are the standard checks, and replacing at the right point costs far less than a thrown track or a damaged final drive. Each product page lists fitment, dimensions and weight, with Compare available to line up options and Ask Simon on hand for fitment confirmation against a machine model and serial.
Undercarriage is heavy, machine-specific and usually urgent when it's needed, so confirming fitment before ordering matters. Send the machine make, model and serial via WhatsApp 07754288583 for a direct check on track and undercarriage availability.
