About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-75
The AirTAC SAIJ32X950-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 875 to 950 mm, letting you dial in the exact endpoint at commissioning without swapping hardware. Built with a SUS304 stainless steel rod, it handles lower force tasks delivering 402 N of push thrust at 0.5 MPa.
This model uses a PT tapered port thread and lacks a magnet, meaning position sensing via CMSE or DMSE switches is not supported out of the box. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock, so live air is required to hold the load. Standard mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-75 Is Used
Machine Changeover
Quickly adjust the 875-950 mm travel window during product size transitions without physically replacing the cylinder or adding external stopper blocks.
Long-Stroke Diverting
Fine-tune the retract position on extended conveyor routing arms to perfectly align with varying pallet depths at commissioning.
End-Position Tuning
Dial in the exact endpoint on automated assembly presses to compensate for mechanical tolerance stack-up over a long 950 mm stroke.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX950-75 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. An adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, whereas a fixed SAI cylinder locks you into one exact dimension. Because this cylinder lacks a magnet, you cannot use reed or electronic sensors for position feedback.
At 950 mm of total travel, the 12 mm rod is highly susceptible to side-loading damage; always use an external guide to support the load. For load-holding without continuous air pressure, this cylinder will not suffice, so consider an external rod lock, a pilot-operated check valve, or the SAIL and BSAI locking cylinder variants.
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 SAIJ32BX950-75 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the nominal 950 mm stroke by up to 75 mm, creating an effective travel window of 875 to 950 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
