Why repair your Cavex CUW-63 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 Cavex CUW-63, 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 Flender equipment for decades — elevators, mixers drives are daily work, not an experiment.
About the Flender Cavex CUW-63
The Flender Cavex CUW-63 is a cavex worm reducer from the H2SH/H3SV, B3SH, Cavex, MOTOX line, rated 5–40 hp across ratios of 5:1–70:1, and most commonly found on elevators, mixers. Flender (ex-Siemens) is the global heavy-industry standard — H/B series helical and bevel-helical units, Cavex worm, and MOTOX gearmotors drive cement, mining, and power plants.
When a Cavex CUW-63 fails, the real decision is economic: a new unit lists at $3,200–$8,400 with a 16–30 week factory queue, a tested used unit trades at $1,280–$6,000 when you can find one, and a standard shop rebuild runs $1,470–$5,000 over 10–15 business days. Our in-house network rate of $1,150–$4,100 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 $34–$83, while we'll pay $150–$1,440 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.
