About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30S
The AirTAC SAIJ200X65-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its 65mm nominal stroke can be dialed back by up to 30mm, creating a precise 35-65mm usable travel window for heavy-duty fine-tuning. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This variant includes a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and carries a built-in magnet (-S) compatible with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports and offers adjustable air cushions at both ends to decelerate high-mass loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30S Is Used
Heavy Pressing Operations
Apply up to 21991N of push force at 0.7 MPa for heavy-duty pressing, using the 35-65mm travel window to dial in the exact compression depth.
Product Size Changeovers
Quickly adapt machinery to new product dimensions by turning the rear adjuster to shorten the stroke, eliminating the need to physically swap cylinders.
Precision End-Stop Tuning
Fine-tune the retracted end position during machine commissioning to prevent mechanical interference, relying on the 30mm adjustment range for flexibility.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30S the Right Cylinder?
Select this 200mm bore cylinder when an 160mm bore (providing 10053N push force at 0.5 MPa) is insufficient for your load. The adjustable 35-65mm travel window is perfect for product changeovers, allowing you to reposition the end-stop at commissioning without swapping the cylinder or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-load holding, consider an AirTAC SAIL or BSAI lock cylinder.
To match this ISO 15552 interchangeable cylinder, specify a 200mm bore, 65mm stroke, 30mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Although the stroke is short, the 40mm rod and M36x2 thread provide excellent rigidity, but always verify external guiding if side loads are present.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-30S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster allows you to trim the 65mm nominal stroke back by up to 30mm, resulting in a usable travel window of 35-65mm. It acts as a mechanical stop and does not lock the load without air pressure.
