High-Performance Polymers Gain Attention in Industrial Motion Components as Wear and Lubrication Requirements Evolve

Moving components in industrial machinery may be relatively small, but their performance can affect the reliability and productivity of an entire machine. Bushings, guides, sliding elements and selected transmission components operate under repeated movement and friction. When wear resistance is insufficient, increased clearance, reduced positioning accuracy or more frequent maintenance can become problems. In highly automated production environments, the downtime required to replace a component can sometimes be more significant than the initial purchase cost of the part itself.

On October 13, igus Japan announced plans to showcase high-performance polymer mechanical components at JIMTOF 2026, including lubrication-free sliding bearings, linear guide systems and other motion components. The solutions are intended for demanding machine-tool environments involving metal chips, coolants and frequent movement, with a focus on durability, reduced maintenance and operational reliability. The announcement reflects a wider engineering consideration: material selection for moving machinery components needs to account for wear and maintenance requirements throughout the component's service life.

Traditional metals offer clear advantages in strength and load-bearing capacity, but certain moving components must also meet requirements for friction, corrosion resistance, weight and lubrication. In applications suitable for engineering plastics, appropriately designed polymer components can provide a different balance of properties. PEEK, PPS and specially modified nylon compounds, for example, can offer different combinations of thermal resistance, mechanical performance and wear characteristics depending on their formulations. Their suitability for continuous sliding or repeated loading cannot be determined by polymer type alone. Actual loads, sliding speed, counterface materials and operating temperature also need to be considered.

Material selection also needs to reflect component geometry and manufacturing requirements. A mechanical guide may place particular importance on dimensional stability, while a transmission component may be more sensitive to impact loads or continuous wear. A material with high mechanical strength is not necessarily suitable if it creates excessive friction or wears rapidly in service. For injection-molded components, glass-fiber or carbon-fiber reinforcement can introduce additional considerations involving fiber orientation, molding shrinkage and dimensional consistency. Improving one property without considering these factors may create difficulties elsewhere in production.

These requirements also create opportunities for application-specific engineering plastics. In industrial component development, TechInherit can evaluate PA6, PA66 and other high-performance materials according to mechanical loads, temperature, wear requirements and processing conditions, while considering the relationship between material formulation, part design, tooling and injection molding. For existing plastic components affected by wear, deformation or excessive production costs, reviewing material and manufacturing conditions together may be more useful than simply selecting a more expensive resin. Applications requiring long-term sliding performance or lubrication-free operation still need appropriate wear and service-life validation.

The role of high-performance polymers in industrial machinery is therefore not limited to replacing selected metal components. Reducing component weight, improving manufacturing flexibility and limiting maintenance requirements can all influence material decisions, provided that the required mechanical performance and durability are maintained. For equipment designed to operate reliably over long periods, component performance throughout its service life can be more important than the initial material price alone.
