About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-100
The AirTAC SAIJ32X220-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning the retract end position. With a 220 mm nominal stroke and a 100 mm adjustment range, it provides a highly flexible 120-220 mm usable travel window for exact product changeovers.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit uses a PT G1/8 port and a 12 mm SUS420J2 stainless steel rod. It includes variable air cushions at both ends and omits the FB, CA, CB, and CR mounts, utilizing a reduced interface of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-100 Is Used
Product Changeovers
Dial the stroke back from 220 mm down to 120 mm to handle varying product lengths on the same line without adding external physical stops.
Commissioning Calibration
Fine-tune the retract end position during initial machine setup to perfectly dial in the 120-220 mm travel window.
End-Position Trimming
Use the 100 mm rear adjustment screw to precisely set the deceleration point without modifying the cylinder's ISO 15552 mounting footprint.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-100 the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI when your machine setup requires variable end stops without physically swapping cylinders. If your application needs greater thrust, stepping up to the 40 mm bore yields 528 N of pull force at 0.5 MPa. The rear adjuster acts strictly as a travel stop for deceleration and does not hold the load without live air; for true drop protection, consider SAIL or BSAI. As a 220 mm stroke exceeds 300 mm, an external guide is not strictly mandated, but the 12 mm rod thread still requires attention to side-load limits. For a true ISO 15552 replacement, match the 32 mm bore, 220 mm stroke, 100 mm adjust, PT G1/8 port, and SUS420J2 rod material.
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 Adjustable Cylinder SAIJ32 SAIJ32AX220-100 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster allows you to shorten the effective travel by up to 100 mm, creating a usable stroke window of 120 to 220 mm. It functions as a mechanical stop and does not lock the load without air pressure.
