FAQ

What work fits NAICS 333995?
  • Produce welded hydraulic cylinders to specified bore, stroke, pressure rating, rod finish, and perform hydrostatic testing with certificates of compliance.
  • Manufacture tie-rod and mill-type pneumatic cylinders with specified mounting styles, factory-installed seals, and end-cap machining.
  • Assemble rotary actuators or vane actuators with required mounting interfaces, torque ratings, and factory performance testing.
  • Deliver custom actuator assemblies with integrated position sensors or feedback connectors as factory-configured units accompanied by calibration and inspection reports.
When is NAICS 333995 a weak fit?
  • Hydraulic system design and integration contracts: system-level design, piping, pump and valve selection without manufacturing new cylinders or actuators.
  • Repair and overhaul services: field or shop rebuilding of existing cylinders where no new factory fabrication of actuator assemblies is performed.
  • Instrumentation and sensor-only suppliers: provision of position transducers, encoders, or sensors without supplying actuators or complete cylinder assemblies.
What solicitation language points to NAICS 333995?
  • Specification lists required bore, stroke, rod diameter, material grades, surface treatments, and hydrostatic or pressure acceptance criteria with test certificates.
  • Statement of work requires delivery of factory-assembled, serial-numbered actuators with material traceability, test reports, and packing lists.
  • RFP requests CAD mounting interface drawings, tolerance tables, and factory calibration, inspection, and performance test records.
