Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 230mm 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 SAIJ32AX230-40S
The AirTAC SAIJ32X230-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 190-230 mm usable travel window, allowing you to dial back the nominal 230 mm stroke by up to 40 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push thrust and 345 N of pull force at 0.5 MPa operating pressure.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. Pneumatic connections use a PT tapered G1/8 port, and the standard adjustable air cushions at both ends help decelerate the moving load over a 27 mm cushion length.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40S Is Used
Product Changeover Dials
Quickly fine-tune the 190-230 mm travel window during format size changes on packaging lines without swapping out the entire cylinder.
Machine Setup End-Stop
Use the 40 mm rear adjuster to set precise retract positions at commissioning, avoiding the need to bolt on physical external stops.
Corrosive Light Assembly
Leverage the SUS420J2 stainless steel rod and 402 N push force for light-duty pressing and positioning in environments requiring rust resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 724 N of push force at 0.9 MPa, stepping down from a 40 mm bore (which yields 528 N of pull at 0.5 MPa) to save space and air volume. An adjustable-stroke cylinder is selected over a fixed-stroke SAI when you need variable end-stops for product changeovers or fine end-position tuning at machine setup. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ32X230-40-S will not hold a load without live air pressure. For load-holding requirements, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To replace an ISO 15552 cylinder with this unit, match the 32 mm bore, 230 mm stroke, 40 mm adjustment range, PT G1/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets. Since the 230 mm stroke is relatively long for a 32 mm bore, always use an external guide to prevent side-load damage to the 12 mm rod and M10x1.25 rod thread.

- ✓ 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 SAIJ32AX230-40S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push thrust and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 724 N of push force.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 230 mm down to 190 mm. It only sets the end position and decelerates the stroke; it does not lock or hold the load without continuous air pressure.
