About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-75S
The AirTAC SAIJ100X155-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 155 mm nominal travel by up to 75 mm. This yields a precise 80-155 mm usable window for commissioning without swapping hardware. It delivers 3927 N of push force at 0.5 MPa and reaches 7068 N at 0.9 MPa.
This variant features a SUS420J2 stainless steel rod (option A) for corrosion resistance and includes a piston magnet for position sensing via CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-75S Is Used
Product Changeover Stops
Quickly shift the 80-155 mm travel window during packaging line format changes without adding external mechanical stops.
Commissioning Fine-Tuning
Dial in the exact retract end-position during machine setup to perfect timing and avoid crushing delicate workpieces.
Variable End-Position Dosing
Adjust the effective stroke on automated filling equipment to accommodate different container heights on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-75S the Right Cylinder?
Select this 100 mm bore when an 80 mm bore (2513 N at 0.5 MPa) is insufficient for moving heavy jigs. The 75 mm adjustment range is ideal for product changeovers requiring vastly different end-stops on the same line. Remember, the rear adjuster is a travel stop, not a lock; for load-holding without live air, use an SAIL or BSAI cylinder. For ISO 15552 replacement, match the 155 mm stroke, 75 mm adjust, PT G1/2 port, and -S magnet.
With a 155 mm stroke, the M20x1.5 rod handles moderate side loads, but for any stroke of 300 mm or more, an external guide is mandatory 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 SAIJ100 Adjustable Cylinder SAIJ100AX155-75S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as a stop that shortens the 155 mm nominal stroke by up to 75 mm, giving an 80-155 mm usable travel window. It only sets the end position and does not lock the load without live air.
