About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-100S
The AirTAC SAIJ32X220-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 120 to 220 mm. Built for precision commissioning, it allows you to dial in the exact retract position without swapping out hardware. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for lighter-duty manipulation tasks.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch placement. It uses a PT tapered G1/8 port and offers adjustable air cushions at both ends to manage end-of-stroke impacts.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-100S Is Used
Machine Changeover
Dial in the retract position up to 100 mm during product size transitions without physically swapping the cylinder or adding external mechanical stops.
Variable End-Stop Positioning
Perfect for light-duty assembly stations where the 402 N push force at 0.5 MPa is sufficient and the exact end-of-stroke must be fine-tuned on the fly.
Sensor-Driven Sorting
The integrated magnet pairs with DMSE electronic sensors to trigger downstream actions accurately within the 120 to 220 mm adjustable travel window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-100S the Right Cylinder?
Choose this 32 mm bore when you need precise variable end-stops for product changeovers rather than a fixed-stroke SAI cylinder. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe holding, consider an SAIL or BSAI cylinder.
To replace an ISO 15552 cylinder, match the 32 mm bore, 220 mm stroke, 100 mm adjustment range, PT G1/8 port, and the -S magnet requirement. Because the total stroke is 220 mm, ensure adequate guiding to prevent excessive side-loading on the 12 mm rod. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32AX220-100S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window between 120 mm and 220 mm, letting you fine-tune the retract position at commissioning without changing the cylinder.
At a 0.5 MPa operating pressure, it provides a push force of 402 N and a pull force of 345 N. At 0.9 MPa, the push force increases to 724 N.
