Standard QGY Series Aluminum Pneumatic Cylinder Barrel

BrandWEIYINGSI
Product originCHINA
Delivery time15~20 DAYS
Supply capacity5000 Meters Per Day

Weiyingjia Technology specializes in the production of aluminum tubes and cylinder components. From CNC processing of aluminum tubes to the final cylinder tubes, we strictly control the entire process. We offer a wide range of specifications (cylinder diameters 32–100mm), support non-standard customization, have a fast delivery time, and offer high cost-effectiveness. It is suitable for various oil-free compressor cylinder and pneumatic component matching requirements.The aluminum tube is processed by high-precision CNC technology. The inner diameter tolerance of the cylinder is strictly controlled within ±0.02mm, and the inner wall surface finish reaches Ra0.8μm. The piston runs more smoothly during reciprocating motion, without any jamming or air leakage. The coaxiality and straightness are precisely controlled to ensure stable cylinder thrust and precise movements. The aluminum cylinder is made of high-quality aviation-grade aluminum base material. It has a low density and light weight, reducing the weight by over 30% compared to traditional steel cylinders. It is corrosion-resistant and shock-resistant, suitable for complex industrial environments such as dusty and humid conditions. It is unlikely to rust or deform during long-term operation, significantly increasing its service life. The inner wall of the aluminum cylinder tube is treated with hard anodizing, which enhances its wear resistance by two times. It supports oil-free lubrication operation, eliminating the need for an oil mist device and preventing oil and gas pollution. The sealing performance is excellent, with a pressure resistance of 1.5 MPa and a working pressure range of 0.1 - 1 MPa. It has strong power and lower energy consumption.

Product Features

QGY Series Aluminum Pneumatic Cylinder Barrel

As the core load-bearing component of the QGY series thin cylinders, the QGY cylinder barrel is made of high-strength aluminum tubes. It is formed through precise CNC machining of the aluminum tubes. Its main function is to provide a stable reciprocating motion chamber for the piston, enabling the conversion of compressed air energy and the output of linear power.

Lightweight advantages: It is made of 6063-T5 high-strength aluminum alloy, with a density only one-third that of steel. It combines lightweight with structural strength, has excellent heat conductivity, and helps the equipment dissipate heat quickly. Compared with steel cylinder barrels of the same specification, it weighs approximately 30%-40% less, reducing the overall load of the equipment, suitable for scenarios such as robotic arms and automated conveyor lines that are sensitive to load, while reducing the loss of installation brackets and extending the overall service life of the equipment.

The surface is treated with hard anodizing, which has a high hardness of the oxide film and micro pores that can adsorb lubricating oil, significantly reducing piston friction loss and adapting to scenarios without oil lubrication, thereby reducing equipment maintenance costs. The Weyingjia QGY cylinder barrel features core advantages such as wear resistance, energy saving, compactness and reliability. It is an efficient and stable pneumatic actuating component used in modern automated equipment.

About Us

We have always focused on the optimization and upgrading of core products such as the QGY series cylinder barrels. The QGY cylinder barrel, as the core component of the oil-free lubrication thin-type cylinder, combines the characteristics of compactness, lightness, efficiency and stability. Its axial dimension is significantly shorter compared to traditional cylinder barrels, making it easy to install and requiring no additional accessories. It is suitable for various scenarios such as automated production lines, packaging machinery, and medical equipment. The company possesses professional equipment such as high-precision hydraulic drawing machines, fully automatic grinding machines, and anodizing production lines, which can achieve H7-level high-precision roundness and Ra0.2-level surface smoothness. Combined with a high-quality oxide film of 15 microns or more, the cylinder barrel is endowed with outstanding wear-resistant and damage-resistant properties, ensuring long-term stable operation.
