About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-30S
The AirTAC SAIJ32X700-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 670 to 700 mm usable travel window. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, fitting compact pneumatic setups requiring precise end-position tuning. The barrel is extruded aluminum with sensor grooves on both sides for straightforward switch placement.
This specific SKU ships with a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. An integrated magnet enables position sensing with AirTAC CMSE reed or DMSE electronic switches. The rear adjustment screw functions as a travel stop to decelerate the load, not a lock, so live air pressure is always required to hold the rod in place.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-30S Is Used
Machine Changeover
Dial in the 670-700 mm end position during product size changes without machining new hard stops.
Assembly Calibration
Fine-tune the retract stroke during commissioning to perfect the seating force of a 402 N assembly press.
Variable End Stops
Adjust the travel limit on a long-stroke diverter to accommodate varying package lengths on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-30S the Right Cylinder?
Choose this 32 mm bore when an application needs 402 N of push force at 0.5 MPa and a variable end-stop within a 700 mm stroke. If your setup requires less force, stepping down to a 25 mm bore is not an option in the SAIJ range, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for commissioning fine-tune adjustments or product changeovers without swapping the cylinder or adding external stops.
Because the nominal stroke is 700 mm, an external guide is recommended to prevent excessive side loading on the 12 mm rod and M10x1.25 rod thread. To replace an ISO 15552 cylinder, match the 32 mm bore, 700 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

- ✓ 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 SAIJ32BX700-30S 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 lets you shorten the effective stroke by up to 30 mm, creating a 670 to 700 mm usable travel window. It acts as a travel stop to set the end position and does not lock the load without live air pressure.
