Sumitomo Gearbox Repair & Rebuild Services
Sumitomo's Cyclo and Paramax drives are built tough, but shock loads, contamination, and worn bearings still take them down — and downtime costs you every hour. Matrix Gear Repair rebuilds the full Sumitomo lineup, including the cycloidal Cyclo 6000 series, Hyponic, Paramax parallel-shaft drives, and Bevel Buddybox units. Ship it in nationwide or schedule field service.
Our techs know the cycloidal disc-and-pin design inside out, so we diagnose the real cause of failure and rebuild to spec — saving you 40–60% over new and getting you running fast. Every unit is spin-tested and warrantied before it ships.
