About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-10S
The AirTAC SAIJ200X155-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 145-155 mm usable travel window, allowing you to dial back the 155 mm nominal stroke by up to 10 mm during commissioning. As the largest standard bore, it generates 15708 N of push force at 0.5 MPa and 21991 N at 0.7 MPa.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses PT tapered G3/4 ports and operates at speeds of 30-500 mm/s. The rear adjuster acts purely as a travel stop to fine-tune end positions without external hardware.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-10S Is Used
Heavy Press Tuning
Fine-tune the 145-155 mm travel window on heavy presses to accommodate material thickness variations without adding external mechanical stops.
Assembly Line Changeover
Adjust the retract end-position by up to 10 mm during product size changeovers on large assembly lines, saving downtime on physical cylinder swaps.
Large Mold Handling
Position heavy 200 mm bore molds with 15708 N of force while using the rear screw to precisely set the final resting position during machine setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-10S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires maximum thrust (15708 N at 0.5 MPa) alongside precise end-position tuning. If you need slightly less force, stepping down to a 160 mm bore yields 10053 N of push force. Choose this adjustable-stroke SAIJ over a fixed SAI when you need to trim the retract end by up to 10 mm for product changeovers without swapping cylinders.
Because the stroke is 155 mm, the 40 mm rod diameter handles high side loads, though an external guide is still recommended for heavy lateral weights. The rear adjuster is a stop, not a lock; it cannot hold the load without live air. For load-holding without pressure, use an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI cylinders. To match this ISO 15552 cylinder, specify 200 mm bore, 155 mm stroke, 10 mm adjustment, PT G3/4 port, and a -S magnet.
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 SAIJ200AX155-10S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 155 mm nominal stroke by up to 10 mm, creating a 145-155 mm usable travel window. It is a travel stop for end-position tuning, not a lock, and does not hold the load without live air pressure.
