Internal-tooth rings inside planetary boxes, slewing bearings, and swing drives. Whatever machine yours lives in, the economics are the same: catch wear early and a repair costs a fraction of replacement; catch it late and you're buying downtime along with new iron. We publish real numbers for both paths — and a cash offer for your worn component — before you ship anything.
Our network handles internal & ring gears from fractional-horsepower packaging drives to mill gears twenty feet across: tooth-flank regrinding, spray-weld buildup and recutting, complete re-manufacture from samples or drawings, matched replacement elements, and full drive rebuilds with new bearings and seals. Standard turnaround is 8–12 business days with 24–72 hour emergency service, versus the 16–30 weeks a factory order can take.
And because we're surplus dealers first, we're the only shop that works both sides of the market: if your internal & ring gears is beyond economic repair, we'll buy it — and often have a tested used replacement on the shelf.
