About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-100S
The AirTAC SAIJ32X180-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window anywhere between 80 and 180 mm. Delivering 402 N of push force at 0.5 MPa, it is engineered for applications requiring exact end-position calibration during commissioning or product changeover without adding external stops. This version includes a magnet for CMSE reed and DMSE electronic sensors, and uses a SUS420J2 stainless steel rod for enhanced durability against moisture.
Unlike a fixed-stroke SAI cylinder, this adjustable model lets you dial in the retract end position on the fly. The rear adjuster acts purely as a mechanical stop to set the travel limit and must not be confused with a lock, as it cannot hold a load without live air pressure. For load-holding requirements without continuous air supply, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract position between 80 and 180 mm during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Size Changeover
Quickly adjust the stroke length on packaging lines when switching between different product sizes, using the rear screw to set new end limits.
Precision Setup Calibration
Fine-tune the end-of-travel position during initial machine assembly to perfect the mechanical timing before locking down the layout.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-100S the Right Cylinder?
Choose this 32 mm bore cylinder when your application demands a highly flexible travel window, as the 100 mm adjustment range is the largest available for this bore size. If your setup requires higher force, stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa, but if you need less force and a smaller footprint, a 32 mm bore is ideal. The SAIJ32X180-100-S features PT tapered port threading and operates at speeds between 30 and 800 mm/s.
This SKU is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 12 mm carbon steel rod core paired with the M10x1.25 thread handles moderate side loads, but because the stroke is 180 mm, you should still verify guiding stability. The integrated magnet works seamlessly with AirTAC CMSE and DMSE switches mounted in the dual-side sensor grooves.

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 SAIJ32AX180-100S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 180 mm nominal stroke by up to 100 mm, providing a usable travel window of 80 to 180 mm. It sets the end position but does not lock or hold the load without live air pressure.
