Pulp & Paper · Nationwide · 24/7

A paper machine runs around the clock and hates to stop.

Refiner, dryer-section, and roll-drive gearboxes, plus stock and fan pumps — torn down, rebuilt to OEM spec, and back on the machine before an unplanned outage eats the whole week.

Gear Force Machine repairs gearboxes, centrifuges, and mixers for pulp & paper mills — refiner and roll-drive gearboxes, dewatering and thickening centrifuges, and stock and pulp mixers and agitators. From the pulp mill and stock prep through the wet end, dryers, and winder, we tear the unit down, inspect and measure every wear surface, and rebuild it to original OEM tolerances — with 24/7 emergency response when the machine is down.

Centrifuge scroll and bowl rebuilds, mixer drive and seal rebuilds, and full gearbox teardowns all happen under one roof — and obsolete or discontinued units are reverse-engineered and machined in-house, so a part number the OEM dropped decades ago never turns a repair into a machine-rebuild project. Every job ships with a written condition report, line-item pricing, free nationwide pickup, and a 3-year warranty on gearbox rebuilds. Machine down right now? Call 832-729-9906.

Frequently Asked

Questions from this industry.

Outages get prioritized — 24/7 intake and same-day start when possible, because we know a down machine bleeds tonnage by the hour. Most standard rebuilds ship in one to four weeks depending on size, condition, and parts. Call 832-729-9906 and we'll give you an honest timeline.

Yes. Refiner and roll-drive gearboxes, dewatering and thickening centrifuges, and stock and pulp mixers and agitators are all core work for us — scrolls, bowls, drives, shafts, and seals measured and reassembled to OEM tolerances with full documentation.

Constantly. Paper machines run for decades, so obsolete units are the norm. We reverse-engineer gears, shafts, and housings from the worn component and machine the replacement in-house, so a discontinued part number doesn't force a capital purchase with a year-long lead time.

Both. We assess on-site when it helps and offer free expedited pickup and delivery nationwide. Most heavy rebuilds happen in our Rosharon, TX shop where we control the machining and testing.

Three years on gearbox rebuilds and 12 months on pump and screw work, covering workmanship and replaced components under normal operating conditions. Questions on coverage? Call 832-729-9906.
