FAQ

What work fits NAICS 333612?
  • Production of helical, bevel, and spur gears to print with material certifications, gear tooth profile inspection reports, and hardness testing records.
  • Assembly and factory acceptance testing of gearboxes including torque testing, vibration analysis, balancing certificates, and test-run data packages.
  • Prototype and low-volume runs for custom speed changers with engineering drawings, bills of materials, first-article inspection reports, and build-to-print documentation.
  • Supply of replacement gearing components with lot traceability, nondestructive inspection results, packing lists, and delivery to maintenance depots.
When is NAICS 333612 a weak fit?
  • Electric motor or generator manufacturing where winding, electrical testing, and insulation class are primary deliverables and electrical assemblies dominate over mechanical gearing.
  • Hydraulic or pneumatic power transmission systems where fluid power components, seals, and valve controls are central rather than machined gear trains and gearboxes.
  • Structural steel fabrication and welded assemblies where the contract focuses on large welded structures and plate work rather than precision gear manufacturing and finishing.
What solicitation language points to NAICS 333612?
  • Technical drawings specify gear tooth profile, tolerances, runout limits, surface finish, and require gear inspection reports and material certificates with deliveries.
  • Performance testing requirements include specified torque capacity, allowable backlash, efficiency measurements, vibration limits, and documented acceptance test procedures.
  • Labor categories request gear designers, CNC gear machinists, heat-treat operators, assembly technicians, and quality inspectors experienced in gear metrology and balancing.
