About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-50S
The AirTAC SAIJ32X290-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore and a 290 mm nominal stroke that can be fine-tuned down by up to 50 mm, providing a usable travel window of 240-290 mm. This adjustability allows you to dial in the retract end-position at commissioning without swapping hardware. It delivers 402 N of push force at 0.5 MPa and includes a SUS304 stainless steel rod for superior corrosion resistance.
This model includes a magnet (-S) for position sensing and uses PT tapered ports. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR variants.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-50S Is Used
Product Size Changeovers
Quickly reconfigure the retract distance by up to 50 mm on packaging lines running varied container sizes, eliminating the need to physically swap out the entire cylinder.
Commissioning End-Stop Tuning
Fine-tune the exact end position during machine setup to achieve perfect alignment, preventing hard mechanical crashes without fabricating custom external spacers.
Adjustable Diverting Stroke
Adapt a diverter arm's reach on a conveyor system on the fly, ensuring gentle product handling by precisely limiting the travel to 240 mm when needed.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-50S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa; step up to a 40 mm bore if you need 628 N, or down to a smaller profile if your load is lighter. The adjustable stroke is ideal for machines running multiple product sizes, letting you shift the end-stop by up to 50 mm during changeovers instead of adding external stops. Because the 290 mm stroke is relatively long for a 32 mm rod, an external guide is recommended to manage side loading and prevent rod binding.
For a direct ISO 15552 replacement, match the 32 mm bore, 290 mm stroke, 50 mm adjustment code, PT port thread, SUS304 (B) rod material, and -S magnet. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the SAIJ cannot hold a load without live air, so consider an AirTAC SAIL or BSAI cylinder if positive load-holding is required.
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 SAIJ32BX290-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 290 mm nominal stroke by up to 50 mm. This creates a usable travel window of 240-290 mm, which can be fine-tuned during commissioning. Note that this mechanism is a stop, not a lock, and requires live air to maintain position.
