Undercarriage Parts
Undercarriage is the fastest-wearing system on any tracked machine and usually the largest single running cost. We trade and stock the full chain: track chains dry, sealed and sealed-and-lubricated, rollers, idlers, sprockets, shoes, adjusters and recoil springs.
Pranthi Enterprise, a spare parts trader and stockist in Surat, Gujarat operating since 1995, supplies undercarriage parts for crawler machines — track chains, track and carrier rollers, front and rear idlers, sprockets, track shoes, adjusters and recoil springs.

Common questions
Which machines take these undercarriage parts?
Crawler machines only — hydraulic excavators, bulldozers and crawler cranes. Wheeled machines such as backhoe loaders, wheel loaders and motor graders have no undercarriage, so nothing on this page fits them.
Do you supply sealed and lubricated track chains?
Yes. We handle dry (unsealed), sealed, and sealed-and-lubricated chain assemblies, and can supply chain with shoes already fitted. Tell us the machine make and model on WhatsApp and we will confirm what suits the hours and application.
Can I buy individual links, pins and bushes rather than a full chain?
Yes. Track links, master links, track pins, track bushes, master pin and bush sets and chain seal kits are all listed separately for partial repair.
