About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-40S
The AirTAC SAIJ32X700-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 660 to 700 mm. It features a SUS420J2 stainless steel rod and a built-in magnet for position sensing. Delivering 563 N of push force at 0.7 MPa, it provides precise end-position tuning during commissioning without requiring external stops.
This model includes PT tapered ports and is fully dimensionally interchangeable with ISO 15552 cylinders. It supports AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster functions strictly as a travel stop to fine-tune the retract end, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-40S Is Used
Machine Setup Tuning
Dial in the exact retract position within the 660-700 mm window during initial commissioning without swapping out the physical cylinder.
Product Size Changeover
Quickly adapt the end-stop on production lines handling varying part lengths, using the 40 mm adjustment range to match new dimensions.
Variable End-Stop Positioning
Replace fixed mechanical stops with the integrated rear adjuster to fine-tune the end of travel for delicate assembly operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX700-40S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires a 660-700 mm stroke range and moderate thrust up to 563 N at 0.7 MPa. If your process demands greater force, stepping up to the 40 mm bore yields 879 N of push force at the same pressure. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, unlike a fixed-stroke SAI cylinder.
Because this unit features a 700 mm stroke, the 12 mm rod requires external guidance to prevent excessive side-loading and premature seal wear. For applications needing the load to stay held without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a brake. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32AX700-40S FAQ
At an operating pressure of 0.7 MPa, this 32 mm bore cylinder provides a push force of 563 N and a pull force of 345 N. The maximum operating pressure is 1.0 MPa.
The rear adjuster allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 660 to 700 mm. It acts as a mechanical stop and does not lock or hold the load without continuous air pressure.
