About the David Brown Series A100
David Brown gear drives have been installed in US sugar mills, mining operations, and marine applications for decades. Now part of David Brown Santasalo, the legacy units are still in service across the country — and when they fail, finding repair expertise is critical. We specialize in legacy David Brown units including the Radicon series and Series A worm boxes.
The A100 is a worm gear unit with a rated capacity of 30–100 HP and output torque of 14,000–56,000 ft-lb. Typical operating weight is 1,080–1,981 lbs. Mounting configurations include Foot, flange.
David Brown units most commonly fail from gear tooth wear in high-load sugar mill applications, bearing fatigue in continuous-duty mining drives, and seal failure in marine environments.
When your David Brown Series A100 fails, downtime costs mount fast. Our standard rebuild turnaround is 8–14 business days with free freight both directions. Emergency 24–72 hour service is available. We publish pricing before teardown — no surprises.
