With the rapid expansion of industrial and collaborative robots, material requirements for joints and sliding components have become increasingly demanding. High wear-resistant nylon has emerged as a competitive alternative to metals and conventional engineering plastics, offering not only extended service life but also weight reduction, noise suppression, and lower maintenance costs.
The wear resistance of advanced nylon materials is derived from synergistic mechanisms at the molecular and tribological levels. During sliding contact, nylon forms a stable transfer film on the counter surface, reducing friction and wear rates. Structural modification and solid lubricant incorporation further enhance performance under boundary or dry friction conditions, making these materials particularly suitable for robotic joints subjected to intermittent motion and high loads.
In robotic joint assemblies, wear-resistant nylon is commonly used for bushings, sliders, gears, and liners. These components demand dimensional stability, fatigue resistance, and thermal control. Optimized crystalline morphology and molecular weight distribution help minimize frictional heat generation and maintain precise positioning accuracy.
For sliding components such as linear guides and actuator interfaces, high wear-resistant nylon provides vibration damping and noise reduction advantages over metallic counterparts. Its fine and uniform wear debris reduces secondary abrasion, contributing to longer system service life even in contaminated or poorly lubricated environments.
