Air Cylinder Series CS2 Large Bore Sizes ø125, ø140, ø160 Lighter installation achieved by CJ1 reducing weight. Die cast rod cover and head CJP cover used to achieve greater CJ2 weight reduction. Rod bore size changed to suit -Z uses, achieving greater weight CJ2 reduction. CS1 CS2 Weight Comparison (Basic Type ø160-100st) Maximum stroke when using rotating bracket Expanded by 1.6 times (compared to series CS1) Allowable lateral load equal to Series CS1 Lighter cylinder reduces self-weight deflection. Stroke range extended to widen use. Even if rod diameter is changed to suit various needs, function remains equal to Series CS1. 1.6 times Mounting angle Series Mounting angle 45° Allowable lateral load of CS1 and CS2 Allowable lateral load (N) Maximum allowable stroke when using clevis bracket Smooth Cylinder Technical data

Compact auto switches can be mounted Improved operability after installation 2-color display auto switches can be mounted, enabling precise determination of mounting position, without error. Operability has been improved by placing the piping port and cushion valve operation position on the same side. Smooth Cylinder Interchangeability with Series CS1 Cylinder mounting dimensions and rod end thread sizes are interchangeable with Series CS1. Minimum operating pressure Cushion seals are now replaceable Maintenance improved by making cushion seals replaceable. Realize stable, low speed...

Weight (kg) Bore size (mm) Head flange Single clevis Double clevis Basic weight Additional weight with magnet (With built-in magnet and auto switch) Additional weight per each 100 mm of stroke Single knuckle Warning 1. Do not use the cylinder as a shock absorber. Using the cylinder as a shock absorber may cause damage. 2. Do not open the cushion valve beyond the stopper. As a retaining mechanism for the cushion valve, retaining ring is installed, and the cushion valve should not be opened beyond that point. If not operated in accordance with the above precautions, the cushion valve may be...

Relation between Cylinder Size and Maximum Stroke The below table shows the applicable maximum stroke (in cm units), found by calculation assuming the case where the force generated by the cylinder itself acts as buckling force on the piston rod, or piston rod and cylinder tube. Therefore, it is possible to find the applicable maximum stroke for each cylinder size using the relationship between the size of the operating pressure and the cylinder support type, regardless of the load ratio. [Reference] If it is stopped with the external stopper on the cylinder extension side, even with a...
