About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-30S
The AirTAC SAIJ32X230-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 200-230 mm usable travel window, allowing you to dial back the 230 mm nominal stroke by up to 30 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This SKU is built with a SUS304 stainless steel rod (option B) for corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It uses PT tapered ports sized G1/8 and offers variable air cushions at both ends, though the adjuster acts only as a travel stop and does not hold the load without live air.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-30S Is Used
Machine Changeover
Quickly fine-tune the retract end-position within the 200-230 mm window when switching between product sizes on a packaging line.
Variable End-Stop Setup
Dial in the exact stroke length during commissioning without adding external mechanical stops to the machine frame.
Corrosive Environments
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in washdown or corrosive manufacturing settings.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-30S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires fine end-position tuning or product-size changeovers without swapping the cylinder or bolting on external stops. If your application needs greater thrust, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if you need less force, dropping to a smaller bore is an option.
For exact ISO 15552 replacement matching, verify the 32 mm bore, 230 mm stroke, 30 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. If your process requires the cylinder to hold a load without continuous air pressure, note that this rear adjuster is not a lock; consider the SAIL or BSAI series instead.
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 SAIJ32BX230-30S 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 operating pressure of 1.0 MPa, it achieves 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm, providing a usable travel window of 200 to 230 mm. It only sets the end position and does not lock or hold the load without live air pressure.
