About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-30S
The AirTAC SAIJ32X220-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the integrated stopper screw, you can fine-tune the retract end position, creating a usable travel window of 190-220 mm from the 220 mm nominal stroke without adding external stops. It delivers a 0.5 MPa push force of 402 N and a pull force of 345 N.
This variant features a SUS420J2 stainless steel piston rod (code A) for improved corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It uses a PT tapered G1/8 port and operates at speeds between 30-800 mm/s. The extruded aluminum barrel provides standard ISO 15552 mounting dimensions while omitting the FB, CA, CB, and CR mountings found in broader ranges.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-30S Is Used
Variable End-Stop Tuning
Dial in the exact 190 to 220 mm retract distance during machine commissioning to perfect product handling without swapping cylinders.
Product Changeover
Quickly readjust the travel window on automated lines when switching between product sizes, minimizing downtime.
Sensor-Ready Positioning
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted end-position in fine-tuned assembly workflows.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-30S the Right Cylinder?
Choose this 32 mm bore adjustable model when your machine setup requires precise end-position tuning during commissioning or product changeover, which a fixed-stroke SAI cylinder cannot provide. If your application requires higher force, stepping up to the 40 mm bore yields a 628 N push force at 0.5 MPa. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. To match this exact configuration, specify a 32 mm bore, 220 mm stroke, 30 mm adjustment, PT G1/8 port, SUS420J2 rod, and the -S magnet option.
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 SAIJ32AX220-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 220 mm nominal stroke down to as little as 190 mm, creating a 30 mm tuning window for exact end-position setup.
