Delrin® for Gears
Delrin® Gears: Engineered for Precision, Quiet Performance & Long Term Reliability
High Performance Gear Solutions for Modern Motion Systems
Delrin® acetal homopolymer (HPOM) is the preferred gear material for designers who demand strength, precision, and durability without the weight, noise, and maintenance drawbacks of metal or hygroscopic polymers. From automotive systems to robotics, consumer devices, and industrial automation, Delrin® enables compact, high performing gear trains that stand the test of time.
Why Choose Delrin® for Gears?
Key features include improved creep and fatigue resistance, enabling greater durability and smarter, more compact, designs. These materials support demanding gear applications across a wide variety of industry sectors.
Superior Mechanical Strength
• High tensile and fatigue strength for long gear life
• Excellent creep resistance under continuous load
• Enables smaller gear designs without compromising performance
Smooth, Quiet Operation
• Naturally low friction for smooth motion
• Exceptional wear resistance
• Inherent noise dampening for low NVH gear trains
Precision You Can Count On
• Outstanding dimensional stability
• Low moisture uptake (0.2–0.8%) prevents swelling and tolerance drift
• Supports tight tolerances and precise tooth geometry
Lightweight & Energy Efficient
• 40–60% lighter than metal gears
• Improves battery life and payload in robots, e-bikes, and portable systems
Clean, Low Maintenance Design
• Self lubricating behavior eliminates grease in many applications
• Reduces maintenance frequency by 30–50%
• Ideal for food safe, medical, and cleanroom environments
