About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-40S
The AirTAC SAIJ32X185-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 145-185 mm usable travel window, letting you dial back the nominal 185 mm stroke by up to 40 mm during commissioning. Delivering 563 N of push force at 0.7 MPa, it fits compact pneumatic setups requiring precise end-position tuning.
This variant integrates a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a piston magnet for position sensing. It is fully compatible with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The extruded aluminum barrel maintains a standard ISO 15552 mounting interface, utilizing a PT tapered G1/8 port.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-40S Is Used
Machine Setup Tuning
Dial in the exact 145 to 185 mm end-of-stroke position during initial commissioning without adding external stopper blocks.
Product Changeover
Quickly adapt travel length on packaging lines handling varying carton sizes by adjusting the rear screw up to 40 mm.
Precision End-Positioning
Fine-tune the retract stroke to guarantee consistent placement of lightweight 32 mm bore components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-40S the Right Cylinder?
Choose this 32 mm bore when an application demands 563 N of thrust at 0.7 MPa but needs on-the-fly travel tuning without swapping cylinders. If your setup requires higher force, stepping up to the 40 mm bore yields 879 N at the same pressure. The SAIJ32X185-40-S is ideal for variable end-stops during product changeovers. Remember that the rear adjuster acts only as a travel stop, not a load lock; the cylinder will not hold position without live air. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 footprint, specify the 32 mm bore, 185 mm stroke, 40 mm adjustment, PT port, and the -S magnet option.

- ✓ 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 SAIJ32AX185-40S FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder provides 563 N of push force and 345 N of pull force. It can deliver a maximum of 80 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke from the nominal 185 mm down to 145 mm. This creates a 40 mm adjustable travel window for fine-tuning end positions without changing the cylinder.
