    Minimize Downtime with Specialty Gear Drives

    When your Johnson Gear Works equipment goes down, every minute costs you money. Whether you’re dealing with worn gears, damaged shafts, or a cracked housing, finding exact replacement parts for legacy or specialized machinery can be nearly impossible. That’s where Specialty Gear Drives steps in. With over 40 years of experience, we don’t just repair gearboxes—we engineer solutions. Our Largo, Florida facility is fully equipped to handle complete rebuilds, reverse engineering, and custom gear manufacturing for all Johnson Gear Works models.

    Engineered Solutions and Unmatched Reliability

    At Specialty Gear Drives, we understand that obsolete parts are often the biggest hurdle in legacy machinery maintenance. If you cannot find a replacement component for your Johnson Gear Works drive, we have the solution. Utilizing our massive archive of blueprints and in-house reverse-engineering capabilities, we can manufacture custom gears up to 48 inches in diameter.
    Opting for a full rebuild rather than replacing your entire unit can save you up to 60% on costs, all while your equipment is handled by Timken Certified Technicians who understand the rigorous demands of industrial production lines. Furthermore, every repair and newly manufactured gear is backed by our industry-leading 24-Month Warranty—and that clock does not start ticking until your drive is officially back in production. If you are facing a critical situation, our 24/7 rush repair services are designed to get your operations up and running as quickly as possible.

    Our Precision Restoration Process

    We refuse to take shortcuts when it comes to restoring your Johnson Gear Works unit to better-than-new condition. Our Precision-Focused Repair Process begins with vibration analysis and comprehensive diagnostics to pinpoint internal wear and root-cause failures prior to full disassembly. From there, components are thoroughly cleaned and measured using thousands of data points to capture exact pitch diameters, tooth profiles, and pressure angles. To ensure the longevity of your drive, we manufacture new shafts and line-bore worn casings to guarantee perfect bearing alignment, which is the most critical factor for the lifespan of your gearbox. If new gears are required, we meticulously match the original Brinell and Rockwell hardness ratings, following up with precision gear grinding to ensure high-speed, low-noise operation. Finally, no gearbox leaves our facility without passing a mandatory, continuous 6-hour test on our custom stands to ensure uncompromising long-term reliability.
