Speed Changer, Industrial High-Speed Drive, and Gear Manufacturing
NAICS 333612 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in manufacturing gears, speed changers, and industrial high-speed drives (except hydrostatic).
Start the review with products liability.
For Speed Changer, Industrial High-Speed Drive, and Gear Manufacturing, the saved research highlights products liability, employee injuries, commercial property. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What types of gears or drives are produced, and what industries or applications are they sold into?
- Are any products supplied into aerospace, defense, nuclear, or other high-consequence end uses?
- What is the replacement cost value of CNC machining centers and other major equipment on the floor?
- Is heat treatment or metal finishing performed in-house, or is it subcontracted out?
- What contractual indemnification obligations does the business typically accept in OEM or supply agreements?
- What is the prior loss history, particularly any products liability claims?
- For Speed Changer, Industrial High-Speed Drive, and Gear Manufacturing, what should the underwriter know about products supplied into aerospace, defense, or nuclear applications?
- For Speed Changer, Industrial High-Speed Drive, and Gear Manufacturing, what should the underwriter know about prior products liability losses, particularly those involving downstream equipment damage or third-party bodily injury at customer facilities?

Establishments in this class design and manufacture gears, speed changers, gear reducers, gear drives, and industrial high-speed drives — excluding hydrostatic transmissions and power transmission equipment for motor vehicles or aircraft. Products typically ship to OEM manufacturers, industrial machinery builders, and end-use facilities where they are integrated into larger mechanical systems. Operations generally involve precision machining, heat treatment, quality inspection, and assembly on a shop floor with heavy CNC equipment.
