About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-30S
The AirTAC SAIJ40X600-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 628N push force at 0.5 MPa and incorporates a SUS304 stainless steel rod for superior corrosion resistance. The integrated -S magnet enables position monitoring with AirTAC CMSE reed and DMSE solid-state sensors.
This specific SKU allows you to dial back the 600 mm nominal stroke by up to 30 mm, yielding a precise 570-600 mm usable travel window. The external rear stopper acts solely as a travel end-deceleration mechanism, meaning it cannot hold a load without continuous live air pressure. For applications requiring true load-holding without pneumatic pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-30S Is Used
Machine Changeover
Dial in the exact end-stop between 570 and 600 mm when switching product sizes on a line, avoiding the need to physically swap cylinders or bolt on external stops.
Commissioning Tuning
Fine-tune the retract position during initial setup to align tooling perfectly, using the rear adjuster to absorb mechanical tolerances without reprogramming the PLC.
Variable End Stops
Adjust the travel limit on the fly for diverter arms handling different package lengths, providing flexible positioning without changing the pneumatic footprint.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX600-30S the Right Cylinder?
Choose this 40 mm bore adjustable cylinder when your setup requires fine end-position tuning during commissioning or product changeover without swapping out the physical cylinder. If your application demands less force, stepping down to a 32 mm bore yields 402N of push force at 0.5 MPa; stepping up to a 50 mm bore provides 982N.
When replacing an ISO 15552 cylinder, match the 40 mm bore, 600 mm stroke, 30 mm adjustment range, PT tapered port thread, and the -S magnet. Because this unit features a long 600 mm stroke, the 16 mm rod can experience side-loading forces; always use an external guide to prevent premature wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ40 Adjustable Cylinder SAIJ40BX600-30S FAQ
The rear adjusting screw allows you to shorten the effective stroke by up to 30 mm from the 600 mm nominal length, creating a 570-600 mm travel window. This stopper sets the end position but does not lock the load without live air pressure.
At a 0.5 MPa operating pressure, it provides 628N of push force and 528N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 1130N.
