About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-75S
The AirTAC SAIJ32X1000-75-S is a double-acting, single-rod ISO 15552 profile cylinder engineered with a rear stroke adjuster. It provides a 925-1000 mm usable travel window by allowing you to dial back the nominal 1000 mm stroke by up to 75 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is built for precision end-position tuning without swapping hardware.
This non-standard 1000 mm stroke variant is made-to-order and features a SUS304 stainless steel rod for superior corrosion resistance. It includes a piston magnet for CMSE reed and DMSE electronic sensors, utilizing PT tapered ports. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-75S Is Used
Variable End-Position Tuning
Dial in the exact retract distance within the 925-1000 mm window during machine setup without installing external physical stops.
Product Size Changeover
Quickly adapt long-stroke automated lines to different product lengths by adjusting the rear stopper screw on the fly.
Long-Stroke Machine Setup
Fine-tune the end-of-stroke position on extended travel axes to perfect timing and prevent mechanical crashes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX1000-75S the Right Cylinder?
Choosing this adjustable-stroke model over a fixed SAI cylinder allows variable end-stops for product changeovers directly at the machine. If your application requires less force, stepping down is not an option at this stroke length, but if you need higher thrust, a 40 mm bore provides 628 N at 0.5 MPa. Because this cylinder features a 1000 mm stroke, the 12 mm rod requires an external guide to prevent excessive side-loading and binding.
For load-holding without continuous air pressure, this cylinder's adjuster is insufficient as it is a stop, not a lock; you should consider an external pilot-operated check valve or the SAIL lock variant. To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 1000 mm stroke, 75 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
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 SAIJ32BX1000-75S 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 801 kgf.
The rear adjuster screw mechanically limits the retract stroke, allowing you to shorten the effective travel from 1000 mm down to 925 mm. It functions as a travel stop and does not lock the load without live air.
