Retlaw Industries is a leading US-based manufacturer of high-precision, custom nylon plastic gears. We partner with companies in the automotive, aerospace, medical and robotics industries to produce durable, quiet and cost-effective gears through our advanced injection molding process.
Whether you need small nylon gears for a delicate project or high-volume production of complex gear systems, our team has the expertise to deliver the perfect solution.
The Advantages of Injection-Molded Nylon Gears
Our gears provide significant performance benefits over traditional metal components in a wide range of applications.
- Quiet & Smooth Operation: Nylon's naturally low friction coefficient ensures minimal noise and smooth power transmission, making it ideal for medical devices and office equipment.
- Excellent Durability & Wear Resistance: Engineered to withstand high loads and repetitive motion, our gears offer a long, maintenance-free service life.
- Lightweight & Corrosion-Proof: Drastically reduce component weight and eliminate the risk of rust and corrosion, which is essential for marine, aerospace and food processing applications.
- Precision & Consistency at Scale: Plastic gear molding allows us to produce thousands of identical gears with tight tolerances, offering a significant cost advantage over machining metal.
Manufacturing a Wide Range of Gear Types
Our four decades of experience and in-house tooling capabilities allow us to manufacture a diverse portfolio of gear types to your exact specifications.
Spur Gears
The most common gear type, used to transmit power between parallel shafts. We produce high-quality plastic spur gears for countless applications.
Worm Gears & Wheels
Ideal for creating large speed reductions in a compact space, common in conveyor systems and material handling equipment.
Bevel & Miter Gears
Used to change the direction of power transmission, typically at a 90-degree angle, for applications like printing presses and other complex machinery.
Gear Racks
When paired with a spur gear, our nylon gear racks convert rotational motion into precise linear motion, perfect for robotics and automation systems.
Nylon Gear FAQs
Are nylon gears strong enough for my application?
While not as rigid as steel, gears made from modern polymers like glass-reinforced nylon offer exceptional strength and durability. Nylon gears are a great choice for many industrial and mechanical applications requiring high wear resistance, low friction and smooth operation under significant loads.
When is nylon the best material for gears?
Nylon is the ideal choice when you need a combination of performance and efficiency. If your application requires low noise, self-lubrication, corrosion resistance and weight savings without sacrificing strength, a custom nylon gear is often the best engineering and business decision.
How does Retlaw ensure gear quality?
We use only high-grade nylon and other engineering polymers, never commodity plastics. Our entire process, from mold design to final inspection, is handled in-house at our Wisconsin facility, so every gear meets our exacting standards.
