About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-10S
The AirTAC SAIJ32X220-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 210 to 220 mm, allowing you to dial back the nominal 220 mm stroke by up to 10 mm during commissioning without adding external stops. Delivering 402 N of push force at 0.5 MPa, it fits compact pneumatic setups perfectly.
This unit includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and a -S magnet for position sensing. The extruded aluminum barrel integrates dual sensor grooves compatible with AirTAC CMSE reed and DMSE electronic switches. It uses a PT tapered G1/8 port and relies on variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-10S Is Used
Machine Setup Calibration
Dial in the exact 210 to 220 mm end-stop during initial machine commissioning to perfect positioning without machining external spacers.
Product Size Changeover
Quickly trim the stroke up to 10 mm when a production line switches to a slightly shorter package or component size.
Precision End-Positioning
Use the rear stopper to guarantee consistent retracted positions for delicate assembly tasks requiring 402 N of thrust.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX220-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa, and step up to the 40 mm bore if you need 628 N of thrust. The 10 mm rear adjuster is ideal for fine-tuning the end position on product changeovers, whereas a fixed SAI cylinder locks you into a single dimension. For strokes of 220 mm or more, ensure you use an external guide to support the load and prevent side-load wear on the 12 mm rod.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 32 mm bore, 220 mm stroke, 10 mm adjustment, PT G1/8 port, and the -S magnet. It supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) but omits FB, CA, CB, and CR brackets. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air, select the SAIL or BSAI series.
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 SAIJ32AX220-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 220 mm down to 210 mm. It only sets the end position and must not be used to hold a load without live air pressure.
