Custom Gear Manufacturing
SDP/SI manufactures gears, mechanical components, and complex gear assemblies for many of the most well-known names in aerospace, medical and robotics. Engineering and manufacturing processes are done in house, giving us better control over lead times and responsiveness to our customer's requests.
From the early stages of product development to high volume production, SDP/SI provides support every step of the way. Our engineers can offer valuable insight during the early design stage of your project. Drawing from 70 years of gear manufacturing experience, customers benefit from our expertise. Design improvements may include a more streamline design, smaller and lighter weight, and better manufacturability leading to cost saving benefits.
SDP/SI custom gear manufacturing services deliver high-quality precision gears, machined parts, and gear assemblies to OEM customer requirements. As the engineer's preferred source we produce a wide variety of gears, including bevel gear sets, anti-backlash gears, helical gears, miter gears, worms and worm wheels, internal gears, gear racks, pinions, plastic gears, planetary gears, gearboxes, speed reducers / increasers, differentials, and custom shafting. Our unique Fairloc Hub design adds increased value, providing superior alignment and ease of adjustability not available elsewhere.
Precision machining in materials that include alloy steel, stainless steel, bronze, brass, acetal, nylon, aluminum, iconel, and titanium, SDP/SI also provides heat treating, anodizing, zinc plating, painting and other services.
Gear CuttingSDP/SI continually invests in the latest gear cutting machines and tooling to ensure our gear teeth are precisely cut to very tight tolerances each and every time. Our Hicksville, NY facility houses over 170 machines, including CNC Bevel Gear Cutting, CNC Gear Hobbing, CNC Gear Shaping, Coniflex Bevel Gear Generators, and Rack Cutting. Facility List

Spur GearsSpur gears are the most common of gears, efficiently transmitting power into motion from one parallel shaft to another. Based on the number of teeth of the driving gear, the drive speed can be reduced or increased. SDP/SI manufactures spur gears for custom gear trains, speed reducers, gearboxes, and planetary gear sets.
Spur gears, internal spur gears, cluster spur gear assemblies are manufactured in metal or plastic to meet your specifications. Internal spur gears are precision machined to precisely mate with an external spur gear. Cluster spur gear assemblies are manufactured for low to high-torque applications.
SDP/SI specializes in planetary gears and custom planetary gear assemblies. Our in house engineering and manufacturing groups work closely with your engineer's design and product development teams to ensure the end result meets your expectations. Whether for individual planetary gear drives or custom built gear assemblies we have the experience, qualified personnel, reliability, and equipment to take your design from prototype to production. We manufacture planetary gearboxes for various applications for the aerospace and defense industries. A partial customer list includes: Boeing, GE Aviation Systems, Israel Aerospace, Kearfott Guidance, Lockheed Martin, NASA, and Raytheon Co.
As a leading manufacturer in the aerospace gearbox industry, we pride ourselves on our many long term relationships. Our custom gearbox assemblies provide the means to position wings, open doors, fuel, instrumentation, loading and steering mechanisms. A wide variety of SDP/SI precision gears and custom gear assemblies can be found on commercial and military aircraft, missiles and satellites around the world. As an AS 9100 certified company, SDP/SI has the ability to develop and manufacture the aerospace components and assemblies required.
Precision CNC Machined Components for all ApplicationsSince 1950 SDP/SI has been providing both stock and custom engineered mechanical components.
