About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-75
The AirTAC SAIJ32X105-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore and a 105 mm nominal stroke, yielding a highly flexible usable travel window of 30 to 105 mm. Operating at 0.5 MPa, it delivers 402 N of push force and 345 N of pull force, making it well-suited for lighter-duty precision tasks.
By turning the external rear stopper screw, technicians can dial in the exact end position during commissioning without swapping out the cylinder or adding external stops. This extruded aluminum profile cylinder includes sensor grooves on both sides for CMSE reed or DMSE electronic switches (requires a -S magnet). It uses a PT tapered port thread and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-75 Is Used
Product Changeovers
Quickly reconfigure the stroke from 30 to 105 mm on packaging lines to accommodate varying product sizes without changing hardware.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve precise mechanical alignment for delicate assembly tasks.
Variable Positioning
Dial in the exact clamping depth on test fixtures where the effective travel distance needs frequent adjustment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-75 the Right Cylinder?
Choose this 32 mm bore unit when an application demands extensive on-the-fly end-position tuning across a 30 to 105 mm window. If your setup requires less adjustment range and slightly higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the adjustment screw acts purely as a mechanical stop and the air cushion only manages deceleration, neither will hold a load securely without live air pressure; for true load-holding, consider an external rod lock or the AirTAC SAIL series.
When replacing an ISO 15552 cylinder, verify the 32 mm bore, 105 mm stroke, 75 mm adjustment range, PT port thread, and your required mounting hardware. The carbon steel rod and M10x1.25 rod thread handle standard loads well, but always ensure proper guiding if side loads are present. The standard speed range is 30-800 mm/s.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32X105-75 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 75 mm. This provides a usable travel window of 30 to 105 mm, enabling fine-tuning of the end position without replacing the cylinder.
At a standard operating pressure of 0.5 MPa, the SAIJ32X105-75 provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
