PRODUCT PARAMETERS
Description
Resin Trapezoidal Lead Screw Nut | Anti-Backlash Flange Nut
Resin Lead Screw Nuts (also known as Plastic Lead Screw Nuts or Engineering Plastic Lead Screw Nuts) are advanced linear motion components manufactured from high-quality engineering resins. These nuts are precision injection-molded to deliver exceptional performance in lightweight, low-noise, and maintenance-free drive systems.
Unlike traditional metal lead screw nuts, our Resin Lead Screw Nuts offer significant advantages in weight reduction, self-lubrication, corrosion resistance, and quiet operation. They are the preferred choice for 3D printers, CNC machines, medical devices, laboratory equipment, automation systems, robotics, and consumer electronics where smooth, efficient, and silent linear motion is essential.
Available in various flange styles — including cylindrical base mounts and round flange designs as shown in the product images above — our lead screw nuts ensure easy installation and reliable performance across diverse applications.

Key Benefits of Resin Lead Screw Nuts
- Ultra-Lightweight Design Made from engineering plastics, these nuts weigh only 1/5 to 1/7 of equivalent metal nuts. This dramatic weight reduction helps manufacturers create lighter, more energy-efficient machines, ideal for portable medical equipment, drones, aerospace models, and handheld devices.
- Excellent Self-Lubricating Properties Advanced formulations incorporate PTFE, molybdenum disulfide (MoS₂), or other solid lubricants. This results in extremely low friction coefficients (typically 0.08–0.15), eliminating the need for external grease or oil. Reduced wear extends service life and minimizes maintenance costs.
- Superior Noise and Vibration Reduction Resin material naturally dampens vibrations and absorbs sound. Operating noise is significantly lower than metal-on-metal combinations, making these nuts perfect for quiet environments such as hospital equipment, laboratory analyzers, office automation, and home appliances.
- Outstanding Corrosion Resistance Highly resistant to acids, alkalis, solvents, and moisture. They perform reliably in harsh or humid conditions where metal nuts would corrode, such as food processing, chemical testing, marine applications, and outdoor equipment.
- Cost-Effective & High Production Efficiency Injection molding enables high-volume production at a fraction of the cost of machined metal nuts — typically 30%–60% lower. Excellent dimensional consistency ensures reliable batch-to-batch quality.
Material Comparison
| Feature | Resin Lead Screw Nut | Metal Lead Screw Nut | Advantage of Resin Version |
|---|---|---|---|
| Weight | Extremely Light | Heavy | 50–80% lighter |
| Friction Coefficient | 0.08 – 0.15 | 0.20 – 0.40 | Smoother, self-lubricating |
| Noise Level | Very Low | Medium to High | Ideal for quiet applications |
| Corrosion Resistance | Excellent | Moderate (requires coating) | No extra protection needed |
| Operating Temperature | -40°C to +120°C (up to 150°C special) | Higher range | Sufficient for most standard uses |
