Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-50S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 105mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-50S
The AirTAC SAIJ32X105-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 55 to 105 mm usable travel window, allowing you to dial back the nominal 105 mm stroke by up to 50 mm during commissioning. This bore size yields 402 N of push force and 345 N of pull force at 0.5 MPa.
Featuring a carbon steel rod and PT tapered port threads, this unit includes a magnet for position sensing. It supports AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The rear adjuster acts purely as a mechanical stop to set the end position, so it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-50S Is Used
Product Changeovers
Quickly reconfigure the 55-105 mm travel window for different product lengths on a packaging line without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve exact placement without machining external spacers.
Variable Positioning
Dial in the exact stroke needed for delicate sorting tasks, relying on the 402 N push force to move lightweight components reliably.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X105-50S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops. If your setup needs less force, stepping down is not an option below 32 mm in this series, but if you need significantly more thrust, a 40 mm bore provides 628 N push at 0.5 MPa. The adjustable stroke is perfect for product-size changeovers on a line, whereas a fixed SAI cylinder locks you into one exact travel distance.
For a true ISO 15552 replacement, match the 32 mm bore, 105 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet option. Keep in mind the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the stroke is 105 mm, side-load is minimal, but always guide the load on longer extensions.
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 SAIJ32X105-50S 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 delivers up to 82 kgf.
The rear adjuster screw lets you mechanically shorten the effective stroke from 105 mm down to as little as 55 mm. This creates a 55-105 mm travel window for fine-tuning the end position at commissioning, but it acts as a stop and does not lock the load without air pressure.
