Hansen Gearbox Repair & Rebuild Services
Hansen industrial gear units (now part of Sumitomo) carry heavy loads in cement, mining, and bulk handling — and a failed unit can idle an entire process. Matrix Gear Repair rebuilds the Hansen range, including the P4 and M4 industrial gear units, to factory spec. Ship yours in nationwide or book on-site field service.
We tear the unit down, identify why it failed, and rebuild with quality bearings and seals, then spin-test before it ships — saving you 40–60% over a new Hansen unit and getting you back online faster. Warranty-backed.
Models & Series We Service:
Hansen P4 industrial gear units, M4 series, Quattro drives, parallel-shaft and right-angle configurations, and obsolete legacy Hansen units.
