About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-100
The AirTAC SAIJ32X270-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 100 mm. This creates a highly flexible 170-270 mm usable stroke window, letting you fine-tune the retract end position during commissioning without swapping out the unit. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Built with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance, this model uses PT tapered ports and supports a speed range of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, although this specific SKU is non-magnetic and does not support CMSE or DMSE switches. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR configurations.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-100 Is Used
Machine Setup Tuning
Dial in the exact 170-270 mm retract position during initial commissioning to perfectly align tooling without machining custom spacers.
Product Changeover
Quickly adapt the stroke end-stop for different sized parts moving down a packaging line by adjusting the rear screw up to 100 mm.
Variable End Stops
Achieve precise end-position tuning on automated test fixtures where the nominal stroke needs slight trimming to meet dimensional tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-100 the Right Cylinder?
Choose this 32 mm bore if your application requires less force than the 40 mm bore (which provides 628 N push at 0.5 MPa) but still needs a highly adjustable travel end. The 100 mm adjustment range is ideal for product changeovers on a line where end-stop positions frequently vary, eliminating the need to bolt on external stops. Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, neither will hold a load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead. When replacing an ISO 15552 cylinder, match the 32 mm bore, 270 mm stroke, PT ports, and the specific 100 mm adjustment code. Since the stroke is 270 mm, ensure proper external guidance to prevent side-load damage to the M10x1.25 rod thread.
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 SAIJ32AX270-100 FAQ
At a 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 270 mm stroke by up to 100 mm, providing a usable travel window of 170 to 270 mm. It only sets the end position and does not lock the load without live air.
