About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-10
The AirTAC SAIJ32X270-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 260-270mm, letting you dial back the nominal 270mm stroke by up to 10mm during machine commissioning. Delivering 402N of push force at 0.5MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-10 Is Used
End-Stop Fine Tuning
Dial in the exact 260-270mm retract position during machine commissioning without adding external physical stops to the fixture.
Product Changeover
Quickly adjust the stroke end by up to 10mm to accommodate slightly different product lengths on the same conveyor line.
Light-Duty Positioning
Leverage the 402N push force at 0.5MPa for precise component placement and light assembly tasks requiring variable end limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-10 the Right Cylinder?
Choose this 32mm bore when you need precise end-stop tuning without swapping components, delivering 402N push and 345N pull at 0.5MPa. If your application requires higher force, stepping up to the 40mm bore yields 628N push at 0.5MPa. The SAIJ32X270-10 uses PT tapered port threads (G1/8) and supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 270mm stroke is relatively long for a 32mm rod, adding an external guide is recommended to prevent excessive side-load wear.
For an exact ISO 15552 replacement, match the 32mm bore, 270mm nominal stroke, 10mm adjustment range, PT G1/8 port, and the SUS420J2 (A) rod material. Remember that the rear adjuster and air cushions only decelerate the travel end; a plain SAIJ does not hold position without live air. For true load-holding without pressure, consider an AirTAC SAIL or BSAI series 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 SAIJ32AX270-10 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It supports a standard operating speed range of 30-800mm/s.
The rear adjuster screw lets you shorten the effective travel from the nominal 270mm down to 260mm. This creates a 260-270mm usable window for fine-tuning the end position at commissioning, acting as a stop rather than a lock.
