Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 275mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10
The AirTAC SAIJ32X275-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 10 mm. This yields a precise 265-275 mm usable stroke window, enabling exact end-position tuning at commissioning without swapping the barrel or adding external stops. It delivers 402 N of push force at 0.5 MPa and operates with a 12 mm SUS420J2 stainless steel rod.
This model uses a PT tapered G1/8 port and relies on variable air cushions at both ends to decelerate the motion. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure. For applications requiring position holding without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10 Is Used
End-Stop Calibration
Dial in the exact 265-275 mm travel window during machine commissioning to perfectly seat parts without adding external mechanical spacers.
Product Changeover
Quickly adjust the retract end-position on a packaging line when switching to a different product size, saving downtime on retooling.
Assembly Positioning
Fine-tune the stroke to press components precisely, using the 402 N push force at 0.5 MPa for light-duty assembly tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX275-10 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa (or 563 N at 0.7 MPa) and require a 275 mm stroke with fine 10 mm rear adjustability. If your application demands higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The adjustable stroke is ideal for machine setup and product changeover, letting you dial in the exact end-stop on the fly rather than machining custom spacers.
This cylinder is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since the 275 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to prevent excessive side-loading on the 12 mm rod. It lacks a magnet, so position sensing requires external switches rather than CMSE or DMSE sensors.
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 SAIJ32AX275-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
A rear adjusting screw acts as a mechanical stop, allowing you to shorten the 275 mm nominal stroke by up to 10 mm, creating a 265-275 mm travel window. This stopper sets the end position but does not lock or hold the load without live air pressure.
