Single acting, Spring return type 2. Single acting, Spring extend type . Use the same spring for the spring return type. . CVJ3: o10, o16 only. IN OUT OUT IN Spring in pre-loaded condition Spring of outlet mounting load When the spring is set in the cylinder When the spring is contracted by supplying air 1. Single acting, Spring return Spring in pre-loaded condition Spring of outlet mounting load When the spring is set in the cylinder When the spring is contracted by supplying air 2. Single acting, Spring extend Note) Avoid applying a load on the cylinder as much as possible, because the value of the output force of a cylinder at the retraction side could be small. Note) Avoid loading the cylinder since the cylinder force at the extension side is a small value. Bore Size Selection CJ2 CVJ3. 1821 Technical data
