About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-30S
The AirTAC SAIJ32X210-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 210 mm nominal travel by up to 30 mm. This creates a precise 180-210 mm usable end-position window at commissioning without swapping out the unit. It features a SUS304 stainless steel rod and a PT tapered port, delivering 402 N of push force at 0.5 MPa.
Because this is a profile cylinder with an extruded aluminum barrel, it includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position and does not hold the load without live air. For position-holding requirements without continuous pressure, consider the SAIL or BSAI locking variants.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-30S Is Used
Machine Setup Tuning
Dial in the exact 180-210 mm retract position during initial commissioning without adding external stopper blocks to the fixture.
Product Changeover
Quickly adjust the stroke end-stop by up to 30 mm when switching the production line to a slightly shorter assembly profile.
Variable End-Stop Forming
Provides a 402 N push force at 0.5 MPa for light-duty forming tasks where the precise bottoming position must be tweaked per batch.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-30S the Right Cylinder?
Select this 32 mm bore when your application requires 402 N push force at 0.5 MPa and a variable end-stop. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N. Choose this adjustable-stroke model over a fixed SAI when you need on-the-fly end-position tuning during product changeovers. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for any stroke over 300 mm, an external guide is recommended. To match this ISO 15552 replacement, verify the 32 mm bore, 210 mm stroke, 30 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.

- ✓ 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 SAIJ32BX210-30S FAQ
The rear adjuster allows you to shorten the 210 mm nominal stroke by up to 30 mm, providing a 180-210 mm usable travel window. It acts as a mechanical stop for end-position tuning and is not a lock, meaning the cylinder will not hold its load without live air pressure.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force, with a maximum thrust of 724 N at 0.9 MPa. The operational speed range is 30-800 mm/s.
