About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100
The AirTAC SAIJ32X900-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 900 mm travel by up to 100 mm for an effective 800-900 mm usable window. It delivers 402 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, position sensing would require adding the -S option for CMSE reed or DMSE electronic switches.
This model uses a PT tapered G1/8 port and operates at speeds between 30-800 mm/s. The rear adjuster functions purely as a mechanical stop to fine-tune the retract end position during commissioning or product changeovers. It is not a locking device, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100 Is Used
Machine Changeover
Quickly adjust the 800-900 mm travel window during product size changeovers without replacing the cylinder or bolting on external stops.
Variable End Stops
Ideal for diverter gates on conveyors where the retract position needs fine-tuning to accommodate different package sizes.
Commissioning Calibration
Dial in the exact end position during initial machine setup to resolve minor mechanical alignment variations across the 900 mm stroke.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX900-100 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning without swapping cylinders or adding external stops; if you need less force, there is no smaller ISO 15552 standard bore, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops, whereas a fixed SAI cylinder is preferred for static, repetitive cycles. To replace this cylinder, match the 32 mm bore, 900 mm stroke, 100 mm adjustment, PT G1/8 port, and SUS420J2 rod material.
Because this cylinder features a long 900 mm stroke, the 12 mm rod requires external guidance to prevent excessive side-loading and premature seal wear. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. For applications requiring true load-holding without live air, 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 SAIJ32AX900-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum force at 1.0 MPa is 82 kgf.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 900 mm nominal stroke by up to 100 mm, creating an 800-900 mm usable travel window. It only sets the end position and does not lock the load without live air.
