About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-75S
The AirTAC SAIJ32X950-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 875 to 950 mm, allowing you to dial back the end-of-stroke position by up to 75 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, reaching 724 N push at 0.9 MPa.
This unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing. It is compatible with AirTAC CMSE reed switches and DMSE solid-state electronic sensors mounted in the dual-side sensor grooves. The fluid port is PT (tapered) G1/8, and the rod thread is M10x1.25.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 875 and 950 mm during machine commissioning to accommodate varying product sizes without external stopper hardware.
Stainless Rod Applications
The SUS304 rod material provides corrosion resistance for packaging lines or light washdown environments where standard carbon steel rods might degrade.
Position Verification
Utilize the integrated magnet with DMSE solid-state sensors to confirm end-of-stroke positions across the adjustable travel window in automated test fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-75S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your machine setup requires fine-tuning the retract position without adding external stops or swapping the cylinder. If your application needs higher thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 950 mm stroke is long, the 12 mm rod diameter should be supported by an external guide to prevent excessive side-load wear. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider the SAIL or BSAI series. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ32BX950-75S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm, providing an adjustable travel window from 875 to 950 mm. It acts as a mechanical stop and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. At 0.9 MPa, the push force increases to 724 N.
