About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-30S
The AirTAC SAIJ200X135-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the travel window from 105 to 135 mm without adding external stops. Built with a robust 40 mm rod and SUS420J2 stainless steel material, it handles heavy loads effectively, delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa. It includes a magnet for position sensing and uses PT tapered ports sized at G3/4.
This adjustable-stroke design simplifies commissioning and product changeovers by letting you dial in the exact retract end-position on the fly. The rear adjuster acts purely as a mechanical stop for deceleration and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider an external rod lock or related series like SAIL or BSAI.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 105-135 mm end-position during heavy press setup, compensating for material thickness variations without swapping cylinders.
Product Size Changeover
Quickly adjust the retract stop for different product lengths on a packaging line, using the 30 mm trim range to adapt to new formats.
Variable End-Stop Automation
Provide a customizable travel limit for automated assembly stations where the final position needs tweaking during machine commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-30S the Right Cylinder?
Choose this 200 mm bore model when your application requires up to 3204 kgf of maximum thrust at 1.0 MPa, stepping up significantly from the 160 mm bore which provides 2050 kgf. The 30 mm adjustment range is ideal for machinery needing variable end-stops during format changes, whereas a fixed-stroke SAI cylinder is better suited for rigid, unchanging travel. It operates at speeds of 30-500 mm/s and supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2.
To match this exact replacement, use bore 200, stroke 135, adjustment 30, PT G3/4 ports, and an -S magnet for CMSE reed or DMSE electronic sensors. Because the 135 mm stroke is relatively short for this large bore, side-load stress is minimal, but always ensure the load is guided externally to prevent rod binding.
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 SAIJ200AX135-30S FAQ
The rear adjuster allows you to mechanically shorten the nominal 135 mm stroke by up to 30 mm, providing a usable travel window of 105 to 135 mm. This stopper sets the end position and aids deceleration, but it does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, it generates 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of thrust.
