About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-30S
The AirTAC SAIJ32X105-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 75 to 105 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and includes a magnet for position sensing. The PT tapered port threads match the standard G1/8 interface for this 32 mm bore.
Because the rear screw acts purely as a mechanical stop, it allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches for exact feedback.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-30S Is Used
Product Changeover
Dial in the exact retract distance from 75 to 105 mm during format size changes on a packaging line without changing hardware.
End-Stop Calibration
Fine-tune the final resting position of a small actuator during machine commissioning to perfect a delicate pressing operation.
Variable Positioning
Adjust the stroke length on the fly for assembly stations that handle multiple part sizes requiring different travel distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX105-30S the Right Cylinder?
Choose this 32 mm bore when an application requires fine-tuning the retract distance within a 75-105 mm window, stepping down from a 40 mm bore that yields 628 N at 0.5 MPa if lower compactness and force are needed. An adjustable stroke is preferred over a fixed SAI cylinder when machine setups involve frequent product changeovers, letting operators dial in the exact end-stop mechanically. For load-holding without live air pressure, note that this adjuster is not a lock; you would need an SAIL or BSAI cylinder instead.
To match this exact ISO 15552 replacement, verify the 32 mm bore, 105 mm nominal stroke, 30 mm adjustment range, PT port threads, and the -S magnet option. Mounting choices are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ32BX105-30S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 75 to 105 mm, though it does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801 N.
