Product Description

[Features]
· Lighter weight makes it possible to reduce device weight
· Die cast rod cover and head cover used for greater weight reduction
· Rod diameter has been changed to suit the application, allowing for greater weight reduction
· Allowable lateral load equal to the CS1 series
· Function remains equal to the CS1 series even if rod diameter is changed to suit the application
· Improved operability after installation
Operability has been improved by placing the piping port and cushion valve operating position on the same side
· Interchangeable with CS1 series
Cylinder mounting dimensions and rod-end thread sizes are interchangeable with the CS1 series
· Maintenance improved by making cushion seals replaceable
· Compact auto switches can be mounted
