Rebuild and Redesign Capabilities

  • In house engineering with many years of gear design experience

  • Active members of the American Gear Manufacturer’s Association (AGMA), including involvement with various AGMA technical committees

  • Services available include gearing related failure analysis, inspection, capacity evaluations, and upgrade studies

  • Experience with helical, spur, worm, bevel gearing, housing and shaft design, bearing selection

  • Old gearboxes can be rebuilt to match the existing design using a combination of existing components and new components

  • Old gearboxes can be rebuilt/redesigned using an existing housing and replacing all old gearing with newly designed and upgraded gearing, shafting, and bearings

  • Old gearboxes can be completely replaced with a drop-in unit that typically includes a newly designed set of gears, shafts, and bearings that improves the gearboxes overall capacity
