Key benefits Smooth surface for reliable operation The rod has a round, smooth exterior with no sand holes or black spots. This reduces wear on mating parts and prevents snagging, contributing to smoother handling and precise alignment in assemblies. Uniform pitch and stable spring action Made from quality raw materials with quality. The tension spring is tight, the texture is clear, force is evenly distributed, and rebound remains stable. This provides predictable performance and consistent response under load. stretchability and durability plasticity and good fatigue strength enable uniform stress and greater firmness over time. There are no surface defects such as sand holes or black spots, and the detailing and texture are refined for lasting reliability in repeated use. Specifications and materials Material: quality raw materials Surface quality: round and smooth exterior with no sand holes or black spots Spring performance: tight tension spring, clear texture, even force distribution, stable rebound Durability characteristics: plasticity, good fatigue strength, uniform stress, refined texture Applications and use scenarios Precision machinery and assemblies Use this rod in systems requiring a smooth, defect exterior to ensure accurate alignment and minimal wear on adjacent components. Springloaded mechanisms and actuators Suitable for devices where a predictable, stable rebound and evenly distributed force are critical to performance and reliability. cycle or demanding environments Ideal for applications with repetitive bending or cycling, where good plasticity and fatigue resistance extend service life and maintain performance over time.
