Why repair your Engineering Class Sprocket & Chain Set with us
Real numbers before teardown
Most shops quote only after your unit is in pieces on their bench. We publish the whole market — new, used, scrap, competitor repair — up front, so you negotiate from strength.
Cheaper and faster
Our network rate beats standard shop pricing by roughly 18–25% on the Engineering Class Sprocket & Chain Set, with turnaround 2–3 days shorter — and 24–72 hour emergency rush when the line is down.
Two-way market maker
If repair isn't the smart move we say so, buy your unit for cash, and can supply a tested used replacement. No other gear shop gives you all three exits.
20+ years of industrial iron
Industrial Surplus World has bought, sold, and rebuilt Rex / Tsubaki equipment for decades — bucket elevators, feeders, dredges drives are daily work, not an experiment.
About the Engineering Class Sprocket & Chain Set
The Engineering Class Sprocket & Chain Set is a engineering-class chain + sprockets from the ANSI/engineering class chain, sprockets line, rated elevator/feeder duty across ratios of ANSI 80-240 / eng class, and most commonly found on bucket elevators, feeders, dredges. Rex (Rexnord) and US Tsubaki engineering-class roller chain and sprockets drive elevators, feeders, and conveyors — we replace, match, and buy surplus chain.
When a Engineering Class Sprocket & Chain Set fails, the real decision is economic: a new unit lists at $5,200–$26,000 with a 16–30 week factory queue, a tested used unit trades at $2,080–$18,700 when you can find one, and a standard shop rebuild runs $2,390–$15,600 over 10–15 business days. Our in-house network rate of $1,860–$12,800 in 8–12 business days beats all of those paths on total cost of downtime — and if the unit is beyond economic repair, its scrap weight alone is worth $81–$198, while we'll pay $250–$4,500 for the core as-is.
Typical failure modes on this family are bearing wear, shaft-seal leakage, and tooth-surface distress from degraded or contaminated oil. A correct rebuild means full teardown, hot-tank cleaning, magnetic-particle inspection of all gearing, verification of bearing-bore tolerances, all-new bearings, seals, shims and gaskets, reassembly to factory clearances, and a loaded run-test with warranty up to 24 months. Done right, it restores full service life at a fraction of replacement cost.
