Product Features
This product is a professional CQ2B compact cylinder tube designed for CQ2B series compact pneumatic cylinders, widely used in automated machinery, pneumatic jigs and precision industrial equipment. It adopts high-purity 6063 aluminum barrel with integral extrusion molding, featuring compact structure, stable hardness, light weight and excellent deformation resistance. It provides better pressure resistance and durability than ordinary aluminum materials, perfectly fitting the narrow installation space of compact cylinders.
As a high-quality pneumatic air cylinder tube, this cylinder tube is finely honed inside with smooth inner surface and high concentricity. It effectively reduces piston friction and seal wear, ensuring stable movement and fast response. It supports long-term high-frequency operation and greatly improves the working stability of pneumatic equipment.
Processed with strict surface treatment, it becomes a premium hard anodized aluminum tube with strong wear resistance, scratch resistance, rust and corrosion resistance. It works stably in dusty, humid and oily industrial environments, effectively avoiding air leakage, jamming and aging problems. With standard industrial size and high compatibility, it can directly replace original cylinder barrels with easy installation, which is an ideal replacement part for pneumatic automation systems.
