About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-30S
The AirTAC SAIJ32X950-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the end-of-travel position during commissioning without adding external stops. With a nominal 950 mm stroke and a 30 mm adjustment range, it provides a usable travel window of 920 to 950 mm. Delivering 402 N of push force at 0.5 MPa, it fits lighter-duty tasks. This specific SKU features a SUS304 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE or DMSE sensors.
Because the 950 mm stroke is lengthy for a 32 mm bore, an external guide is recommended to prevent rod sag and handle side loads. The rear adjuster acts purely as a mechanical stop to set the retract position; it does not lock the load without live air pressure. For load-holding requirements, consider an external pilot-operated check valve or the related SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-30S Is Used
Variable Length Stops
Dial in the exact retract distance on a packaging conveyor to handle different carton sizes without physically changing the cylinder.
Machine Commissioning
Fine-tune the 920-950 mm travel end-point during initial setup to perfectly time the machine cycle and avoid hard mechanical crashes.
Product Changeover
Quickly adjust the rear stopper screw when switching the production line to a new product format, minimizing downtime.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-30S the Right Cylinder?
Choose this adjustable model when your machine setup requires variable end-stops or product changeovers within that 920-950 mm window, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your application demands higher force, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa, but the 32 mm bore is ideal where space is constrained and loads are light.
When replacing an ISO 15552 cylinder, verify the bore, the 950 mm nominal stroke, the 30 mm adjustment, the PT tapered port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options.
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 SAIJ32BX950-30S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 30 mm from the 950 mm nominal stroke, giving a usable window of 920 to 950 mm. It functions as a travel stop for end-position tuning and does not hold the load without continuous air pressure.
