For almost 40 years, Precision Gear has supplied a broad variety of close tolerance gearing and services for defense applications. The company handles no government contracts directly, but instead services contractors and subcontractors on defense related components and assemblies. Our inspection capabilities and documentation can be suited to meet any customers needs including first article inspection, 100% inspection and on site auditing by governmental authorities. We utilize NADCAP and other certified special process vendors as required. We offer services on a “made complete” or contract basis depending on customer requirements.
