About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-50
The AirTAC SAIJ32X180-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel. With a 180mm nominal stroke and a 50mm adjustment range, it provides a usable travel window of 130-180mm. This allows precise end-position tuning at commissioning without adding external stops. It delivers a 0.5MPa push force of 402N and a pull force of 345N.
This model incorporates a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts strictly as a travel stop for deceleration alongside the variable air cushions, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-50 Is Used
Product Changeover
Dial in the 130-180mm travel window to accommodate different package lengths on a packaging line without changing the cylinder.
End-Position Tuning
Fine-tune the retract end-position during machine commissioning to avoid mechanical interference and perfect the timing.
Variable End Stops
Set custom stroke limits on the fly for testing different physical components or calibrating automated assembly stations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-50 the Right Cylinder?
Choose this 32mm bore when you need precise variable end-stops for product changeovers, stepping down from a 40mm bore that provides 628N of push force at 0.5MPa. An adjustable stroke is ideal for setups requiring fine-tuning without swapping the cylinder, unlike a fixed SAI model. Since the rear adjuster only sets the travel end and is not a lock, use a SAIL or BSAI cylinder if your application requires load-holding without live air. For an exact ISO 15552 replacement match, verify the 32mm bore, 180mm stroke, 50mm adjustment, PT G1/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting.

- ✓ 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 SAIJ32BX180-50 FAQ
At 0.5MPa operating pressure, it provides a push force of 402N and a pull force of 345N. At the maximum 1.0MPa pressure, the push force reaches 724N.
The rear adjuster allows you to shorten the 180mm nominal stroke by up to 50mm, creating a usable travel window of 130-180mm. It functions as a mechanical stop to set the end position and does not lock the load without air pressure.
