⚙️ We don't play guessing games with your Alten gearbox.

Here's how it works: Complete teardown. Industrial-grade cleaning. Precision measurement on every single component. The parts that make the cut? Rebuilt to spec. The ones that don't? We manufacture them from scratch—helical, bevel, worm gears, you name it.

Before your gearbox leaves our shop, it runs through a grueling 6-hour test. We're checking heat signatures, vibration levels, and hunting for even the tiniest leak. Only then does it earn our 24-month warranty—which doesn't even start ticking until YOU put it back into production.

No shortcuts. No compromises. Just precision engineering backed by decades of experience.

🚨 Your Amarillo gearbox just failed. Now what?

Option A: Call the OEM, wait 6-8 weeks, watch your production line collect dust.

Option B: Call National Gear Repair, get a 24-hour emergency rebuild, and be back online before your coffee gets cold.

We don't just repair Amarillo right angle gearboxes—we reverse-engineer worn gears, manufacture custom shafts in-house, and run every unit through a rigorous 6-hour test for heat, vibration, and leaks before it ships.

The best part? Our 24-month warranty doesn't even start until you put the gearbox back into production.

Downtime is expensive. We make it optional.

🔍 Googled your Bohmer gearbox part number and came up empty? Good. That's where we start.

Some gearboxes don't come with a catalog, a parts desk, or a quick reorder button. When a Bohmer unit goes down, most shops shrug and quote you a replacement. We pull it apart instead.

Every gear and shaft gets cleaned, inspected, and measured. Anything that can't be saved gets reverse-engineered and manufactured in-house: helical, herringbone, bevel, worm, ring gears, and more. Then the rebuilt unit runs on our test bench for 6 hours, checking for heat, vibration, and leaks, before it ships with a 24-month warranty.

No part number? No problem. No catalog? No problem.

Baumüller Gearbox Trivia Time! ⏰

Did you know Baumüller started as a humble electric motor repair shop in Nuremberg back in the 1930s? Fast forward to today, and they're an international industrial drives giant with over 1,900 employees worldwide.

German engineering at its finest — but even the best-built gearboxes eventually need expert care.

When your Baumüller gearbox starts grinding, leaking, or just plain quits, we're the team that brings it back to life. Our 12-point inspection catches what others miss. Our in-house manufacturing means we can rebuild gears and shafts that OEMs no longer stock. And our 6-hour test run? That's how we guarantee zero surprises when you fire it back up.

Every rebuild comes with a 24-month warranty and flexible financing options to keep your cash flow healthy.

Got a Baumüller giving you grief? We're just a call away!

Ever wonder what it takes to manufacture a gear the size of a small swimming pool? 🏊‍♂️

We're talking 20-foot girth gears for ball mills—precision-engineered to match OEM specifications and hardness ratings. These aren't decorative. They're the backbone of grinding operations in mining, cement, and mineral processing.

Here's the deal: A ball mill is a massive rotating drum that pulverizes material using steel balls. The pinion gear drives the whole operation. When it fails, production stops. When production stops, money walks out the door.

At National Gear Repair, we handle the full spectrum: pinions, girth gears, drive gearboxes, and barring drives for ball mills, SAG mills, and rotary kilns. Each unit gets a 6-hour test run before it leaves our shop, backed by a 24-month warranty.

Got an emergency? Free quotes. Free freight. Nationwide. 🚚

🗂️ Your "obsolete" Black Clawson gearbox? We've got the blueprint for that.

Most shops will tell you it's too old. That parts don't exist. That you need to retrofit your entire system. We say: not so fast.

At National Gear Repair, we've been blueprinting every gearbox we touch for over 40 years. Black Clawson Hydrapulpers, pulper drives, paper mill workhorses from the 1970s—if it's been through our shop, we've got the specs archived and ready to go.

Black Clawson started in 1873 in Hamilton, Ohio, building machines for the paper industry. Those mills were designed around their equipment. Replacing a gearbox isn't just expensive—it's a full-blown engineering project.

Rebuilding? That's where we come in.

We manufacture gears and shafts in-house when OEM parts are long gone. Every rebuild gets a 6-hour bench test and a 24-month warranty that doesn't start until you put it back into production.

Your legacy equipment deserves legacy-level expertise.

🛣️ The Gearbox That Built America's Roads

Harry Barber and William Greene started with a simple idea: stop breaking backs moving material by hand. Their conveyors and bucket loaders changed construction sites across the country.

But the real game-changer came in 1932 when Barber patented a machine that could mix and lay asphalt in one pass. That innovation became the backbone of modern road construction.

Barber-Greene was eventually absorbed into Astec Industries. The name faded. But the gearboxes? They're still out there—still grinding away in pugmills, still keeping asphalt plants running strong.

The challenge is that most shops won't touch them. Parts are scarce. Documentation is buried. Experience is rare.

We're the exception. At National Gear Repair, we specialize in bringing legacy equipment back to life. We manufacture replacement gears and shafts from scratch when OEM parts don't exist. Every rebuild gets a full 6-hour test run to ensure it's ready for the job.

Don't retire equipment that still has decades of life left in it.
