Industrial Surplus World has bought, sold, and rebuilt Horsburgh & Scott equipment for decades — rotary kilns, dryers drives are daily work, not an experiment.
The Kiln Girth Gear & Pinion Set is a girth gear + mating pinion set from the Girth gears, pinions, custom drives line, rated kiln drives across ratios of custom, and most commonly found on rotary kilns, dryers. Horsburgh & Scott builds and rebuilds the biggest open gearing in America — mill girth gears, pinions, and custom heavy boxes since 1886.
When a Kiln Girth Gear & Pinion Set fails, the real decision is economic: a new unit lists at $120,000–$520,000 with a 16–30 week factory queue, a tested used unit trades at $48,000–$374,400 when you can find one, and a standard shop rebuild runs $55,200–$312,000 over 8–16 weeks. Our in-house network rate of $43,100–$255,800 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 $2,880–$7,040, while we'll pay $5,800–$89,900 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.
