About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-30S
The AirTAC SAIJ32X270-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 240 to 270 mm, allowing you to dial back the nominal 270 mm stroke by up to 30 mm during commissioning without swapping out the unit. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This SKU is built with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered port threads (G1/8), and the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-30S Is Used
Machine Setup Changeover
Fine-tune the 240-270 mm travel window during line changeovers to accommodate slightly different product lengths without replacing the cylinder.
Variable End-Stop Positioning
Dial in the exact retract position within the 30 mm adjustment range during commissioning to perfect the pickup point for delicate components.
Light-Duty Assembly
Leverage the 402 N push force at 0.5 MPa and SUS420J2 stainless rod for precise, corrosion-resistant actuation in small assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-30S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning on a 270 mm stroke, delivering 402 N of thrust at 0.5 MPa. If your application requires significantly more force, stepping up to the 40 mm bore yields 628 N at the same pressure. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product changeovers rather than machining custom external stops.
Because the 270 mm stroke creates a long extension, the 12 mm rod and M10x1.25 thread still require an external guide to handle side loads. The rear adjuster acts solely as a travel stop to set deceleration; it does not hold the load without live air pressure. For load-holding without continuous pressure, use a SAIL pneumatic lock or BSAI clamp-lock cylinder. This unit is dimensionally interchangeable per ISO 15552 mounting interfaces, using the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ32AX270-30S 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 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 effective stroke from 270 mm down to 240 mm. It allows precise end-position tuning without adding external stops, though it does not lock the load without live air pressure.
