Sprockets & Drive Segments

Machined sprockets and bolt-on segment rings. Tooth count and pitch are matched to the chain so both wear evenly — fitting a mismatched sprocket is the fastest way to destroy a new chain.

Hard-to-find part? If you can send a drawing or a sample, we can have it machined or produced to match — including parts that are no longer available from the OEM.

Beyond excavators

We also source other industrial products from China

Excavator parts are our main line, and that is where our knowledge is deepest. But we buy from Chinese factories every week, so if you need bearings, steel, fasteners, electric motors, pumps, valves, generators, truck or agricultural spares, hand tools or workshop equipment — send the specification, part number or a photo, and we will check two or three factories and come back with an FOB price and lead time.

Not sure which part you need?

Send a photo of the old part with the machine model. We will identify it and come back with options.
