Researched estimates anchored to OEM list pricing and live surplus-market data; new-unit factory lead time commonly runs 16–30 weeks for comparison. Send your nameplate for a confirmed number.
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.
Our network rate beats standard shop pricing by roughly 18–25% on the H3SH-11, with turnaround 2–3 days shorter — and 24–72 hour emergency rush when the line is down.
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.
Industrial Surplus World has bought, sold, and rebuilt Flender equipment for decades — cement, mining mills drives are daily work, not an experiment.
The Flender H3SH-11 is a helical parallel-shaft, 3-stage from the H2SH/H3SV, B3SH, Cavex, MOTOX line, rated 75–400 hp across ratios of 22.4:1–112:1, and most commonly found on cement, mining mills. 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 H3SH-11 fails, the real decision is economic: a new unit lists at $24,000–$62,000 with a 16–30 week factory queue, a tested used unit trades at $9,600–$44,600 when you can find one, and a standard shop rebuild runs $11,000–$37,200 over 8–16 weeks. Our in-house network rate of $8,600–$30,500 in 4–10 weeks beats all of those paths on total cost of downtime — and if the unit is beyond economic repair, its scrap weight alone is worth $432–$1,056, while we'll pay $1,150–$10,700 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.
