About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-20S
The AirTAC SAIJ32X185-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a 402N push force at 0.5 MPa, utilizing a 12mm rod and G1/8 port. The integrated -20 adjustment code creates a 165-185mm usable travel window, allowing you to dial in the exact retract end-position during commissioning without adding external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for use with CMSE reed or DMSE electronic sensors. It retains the standard extruded aluminum barrel with dual sensor grooves while offering a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-20S Is Used
Product Changeovers
Quickly adjust the 165-185mm travel window to accommodate slight variations in product dimensions on a packaging line without swapping hardware.
Machine Setup
Fine-tune the retract end-position during initial commissioning to perfectly align a pick-and-place head, avoiding costly mechanical shimming.
Variable End Stops
Dial in the exact stopping point for a delicate testing fixture, using the rear screw to set the precise deceleration point for the load.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-20S the Right Cylinder?
Choose this 32mm bore when an application requires fine-tuning of the end-stop within a 165-185mm travel window, rather than committing to a fixed 185mm SAI cylinder. If your setup demands higher thrust, stepping up to the 40mm bore yields 628N at 0.5 MPa. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a lock; for load-holding without live air pressure, consider an external rod lock or the SAIL series.
When replacing an ISO 15552 cylinder, match the 32mm bore, 185mm nominal stroke, 20mm adjustment range, PT tapered port thread, and the -S magnet requirement. Because the 185mm stroke approaches the mid-range of the 32mm bore, ensure the 12mm rod is adequately supported to prevent excessive side-loading on the seals.
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 SAIJ32BX185-20S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 20mm, creating a usable travel window of 165-185mm. It sets the travel end and deceleration point but does not lock the load without live air pressure.
At 0.5 MPa, the SAIJ32X185-20-S provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
