Description
The CJPB Series mini cylinder pneumatic actuator combines a robust single-acting mechanism with a spring return and adjustable stroke feature, allowing custom positioning to fit diverse automation needs. Available in bore sizes from 4mm to 15mm with strokes typically ranging from 5mm to 40mm, this mini cylinder maximizes functionality while minimizing installation space. The aluminum body ensures durability and corrosion resistance, while the panel mount facilitates easy integration in machinery. Its simple pneumatic operation with a single port promotes efficient air use. CJPB mini cylinders are widely used in automation equipment, production lines, and small machinery where compact size and stroke flexibility are critical.

Installation and Maintenance
Installation
Select appropriate mounting style: panel mount for recessed installation is recommended for compactness.
Connect pneumatic tubing using one-touch fittings for secure and fast connection.
Adjust the stroke length carefully by setting the end-position stopper to attain the precise movement required.
Confirm all fittings and connections are tight and leak-free before operation.
Maintenance
Periodically inspect pneumatic tubing and fittings for wear or leakage.
Clean and lubricate seals during scheduled maintenance to maintain smooth operation.
Replace seals if air leakage or reduction in force is noticed.
Avoid exposure to corrosive substances and extreme temperatures to extend cylinder life.
Use compatible speed controllers if operating at high piston speeds to prevent damage.
