SCA2 Series Variation and option selection table Note 1. Only for S2 side. Note 2. Increase of rod seal and bearing increases resistance value. This results in the different minimum starting pressure. Note 3. The installation position of value is different from standard. Note 4. Minimum starting pressure on the side of S2 is higher than low friction standard type. Contact CKD for details. Note 5. Resistance of bellows at stretch motion rises the value of minimum starting pressure. Contact CKD for details. Note 6. Refer to the Clean Component System (Catalog No. CB-033SA) for details on new...

Pneumatic components Safety precautions Always read this section before starting use. Refer to Intro 71 for general notes of cylinders and Intro 78 for cylinder switches. Medium bore size cylinder SCA2 Series Design & Selection Do not operate cylinders synchronously. Do not move more than one workpiece using more than two cylinders with position locking mechanism simultaneously. One of the cylinder's locks may not be released. Install a flow control valve on the cylinder. Install a flow control valve on the cylinder. Use within the applicable piston speed range for each cylinder. 2....

SCA2 Series Generally, the speed is stable when the load factor is lower when air pressure is higher. Keep the load factor at 50% or less. 4. Low hydraulic type SCA2-H CAUTION Select low hydraulic cylinder combined with the converter unit. 5. Coolant proof type SCA2-G2/G3 Do not apply the deviated load onto the piston rod. It could shorten scraper and bearing life. When using the G2 or G3 Series and the coolant or water does not splatter, the piston rod's lubrication could be spent and cause the life to shorten. Use the G or the G1 Series in this case. Maximize operation by combining the...

SCA2 Series Installation & Adjustment 1. Stroke adjustable type SCA2-R CAUTION Accurately lock the stud bolt with a lock nut. Release air before adjusting stroke. Do not tighten the stud bolt as shown in Fig 1. Tighten the stud bolt as shown in Fig.2. Do not tighten the lock nut as shown in Fig.2. Tighten the lock nut as shown in Fig. 1. If the above precautions are not observed, the seal washer may break after 1 or 2 adjustments. If piping on the side with the lock is thin and long, or if the speed controller is separated from the cylinder port, exhaust may slow, taking time for the lock...

SCA2 Series During Use & Maintenance Stopper spring Stopper piston Hexagon socket head cap bolt M4 x 30 When using the cylinder with air cushion, if the air cushion needle on the lock mechanism side is tightened too tight, the piston could bounce at the stroke end causing the sleeve and stopper piston to collide and damage the locking mechanism. If the air cushion needle is opened too far, the piston could spring back at the stroke end and cause similar damage. Adjust the air cushion needle so that the piston does not bounce. For safety purposes, prevent the load from dropping under its own...
