The CJP Series Pin Cylinder (Single Acting) is a compact pneumatic actuator designed for positioning, indexing, locking, and stop mechanisms in automated machinery. Utilizing a spring-return structure, it delivers reliable linear motion while minimizing air consumption and simplifying control systems.
With its miniature dimensions, durable construction, and maintenance-free operation, the CJP Series is an ideal solution for precision automation equipment where installation space is limited and accurate positioning is required.
The CJP Series Pin Cylinder is specifically developed for applications that require precise positioning and locking functions within a compact installation space. Its single-acting spring-return design ensures dependable operation while reducing pneumatic circuit complexity and compressed air usage.
Available in small bore sizes ranging from Ø6 mm to Ø15 mm, the CJP Series is well suited for lightweight automation tasks that require accurate and repeatable motion.
