About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100
The AirTAC SAIJ32X225-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 225 mm nominal stroke to anywhere within a 125-225 mm usable window. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet.
This unit is built with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads (G1/8). The rear adjustment mechanism acts purely as a mechanical stop to set the end position and relies on the integrated air cushions for deceleration. It is not a locking device and cannot hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100 Is Used
Variable End-Stop Positioning
Dial in the exact clamping distance on the fly using the 100 mm adjustment window, accommodating multiple part sizes on a single fixture without changing cylinders.
Machine Changeover Setup
Quickly reconfigure the travel limit from 225 mm down to 125 mm during product line changeovers, minimizing downtime and eliminating the need for external mechanical stops.
Light-Duty Assembly Tuning
Leverage the 402 N push force and fine-tune the stroke to perfect the seating depth of light components during automated assembly processes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa but demands highly flexible end-position tuning. The massive 100 mm adjustment window allows you to dial in the exact travel needed during commissioning or product changeovers without swapping out the physical cylinder or adding bulky external stops. If you need higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 225 mm stroke, PT G1/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the nominal stroke is 225 mm, you should ensure adequate guidance to prevent excessive side-loading on the 12 mm rod. For applications requiring the load to be held in place without air pressure, this cylinder is insufficient; consider the SAIL or BSAI series 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.
Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-100 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 225 mm nominal stroke down to a minimum of 125 mm. The integrated air cushions handle the deceleration, but the adjuster itself does not lock or hold the load without live air pressure.
At a standard operating pressure of 0.5 MPa, the SAIJ32X225-100 provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at its maximum operating pressure of 0.9 MPa.
