About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-75
The AirTAC SAIJ200X155-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 80 to 155 mm, allowing you to dial back the 155 mm nominal stroke by up to 75 mm during machine commissioning. This massive bore generates 15708 N of push force at 0.5 MPa, making it suitable for heavy-duty press and lift operations.
Equipped with a SUS420J2 stainless steel rod and PT tapered port threads, this unit handles demanding environments. The rear adjuster acts purely as a mechanical stop to set the end position; it does not hold the load without live air pressure. For position holding, an external rod lock or SAIL cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-75 Is Used
Heavy Press Tuning
Dial in the exact 80 to 155 mm end-position for high-force pressing tasks without adding external mechanical stops.
Product Changeover
Adjust the retract stop by up to 75 mm on the fly to handle different package sizes on a heavy-duty sorting line.
Machine Setup
Fine-tune the rear stopper during commissioning to perfect the stroke length for new automated assembly equipment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-75 the Right Cylinder?
Choose this 200 mm bore when 160 mm falls short, as the 160 bore yields 10053 N push at 0.5 MPa compared to this model's 15708 N. The 75 mm adjustment range is ideal for production lines running varying product sizes, letting operators change end-stops without swapping cylinders. Since the 155 mm stroke is below the 300 mm threshold, side-load stress is manageable, but an external guide is still recommended for heavy lateral loads. For fixed travel without the adjusting screw, select the standard SAI cylinder. To hold loads safely without compressed air, specify a BSAI clamp-lock cylinder instead.
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.
