( Brand: Parker ), ( Manufacturer Part Number: 4.00CJALU1482.500 ), ( Part Type: Pneumatic Cylinder )
The **Parker Hannifin 4.00CJALU1482.500** is a high-performance, single-acting pneumatic air cylinder designed for demanding industrial applications where precision, reliability, and durability are paramount. Part of Parker s renowned **CJALU** series, this cylinder combines robust construction with advanced engineering to deliver consistent, high-efficiency motion control in automated systems, manufacturing equipment, and material handling processes. With a **4-inch bore diameter (101.6 mm)**, this cylinder offers a substantial force output of **1,482.5 pounds (663.8 kgf)** at maximum pressure, making it ideal for applications requiring substantial linear force, such as clamping, pressing, or heavy-duty positioning tasks. The **LU (Lubricated Union) mounting style** ensures secure, leak-proof connections, reducing maintenance downtime and enhancing operational longevity, while the **CJALU** design incorporates Parker s proprietary **sealing and rod guidance systems** to minimize friction, wear, and air leakage, even under high-cycle operation.
Constructed from **high-strength steel**, the cylinder s body and end caps are precision-machined to exacting tolerances, ensuring structural integrity and resistance to fatigue even in harsh environments. The **standard rod diameter of 1.5 inches (38.1 mm)** provides a balanced strength-to-weight ratio, optimizing both load-bearing capacity and energy efficiency. The cylinder features **Parker s advanced piston and rod sealing system**, utilizing high-performance elastomers and labyrinth seals to maintain air pressure integrity while resisting contamination from dust, debris, or moisture critical for applications in cleanrooms, food processing, or outdoor industrial settings. Additionally, the **integrated cushioning system** on both the rod and cap sides dampens impact forces, extending the life of the cylinder and reducing noise levels during rapid extension and retraction cycles.
For enhanced versatility, the **4.00CJALU1482.500** is equipped with **Parker s patented **Quick-Connect** fittings**, allowing for rapid installation and disconnection without tools, streamlining maintenance and setup procedures. The cylinder s **standard stroke length of 20 inches (508 mm)** provides ample travel for most industrial applications, though Parker offers customizable stroke options to accommodate specific design requirements. Compatible with standard **1/4-inch NPT air supply lines**, this cylinder operates efficiently within a pressure range of **0 to 100 PSI (0 to 6.9 bar)**, though its robust construction allows for short-term overpressure tolerance for emergency or peak-load scenarios. The **smooth, low-friction operation** is further enhanced by Parker s **rod guide system**, which minimizes lateral play and ensures precise, repeatable motion essential for applications in CNC machinery, robotic systems, or automated packaging equipment.
Beyond its mechanical performance, the **4.00CJALU1482.500** is engineered with **safety and efficiency** in mind. Its **double-acting rod seal** prevents air leakage during retraction, while the **integrated drain ports** facilitate easy maintenance by allowing trapped moisture or contaminants to be purged without disassembling the cylinder. The cylinder s **modular design** also supports easy integration with Parker s extensive range of accessories, including **position sensors, magnetic switches, or custom end-of-stroke buffers**, enabling fully automated control in complex systems. Whether deployed in **automotive assembly lines, aerospace component handling, or heavy-duty material sorting**, this cylinder delivers **uncompromising performance**, combining Parker s reputation for innovation with the practical durability required in industrial environments.
