About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-20S
The AirTAC SAIJ32X195-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 175-195 mm usable travel window, allowing you to dial back the nominal 195 mm stroke by up to 20 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS304 stainless steel rod for superior corrosion resistance.
This pneumatic actuator features a PT tapered port (G1/8) and an integrated magnet for position sensing. You can fine-tune the retract end-position without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-20S Is Used
Machine Changeover
Quickly adjust the 175-195 mm travel window to accommodate different product sizes on the same production line without changing the cylinder.
End-Position Tuning
Fine-tune the retract stroke by up to 20 mm during initial commissioning to perfect the seating of delicate components.
Corrosive Environments
Leverage the SUS304 stainless steel rod for reliable actuation in packaging or food-grade areas requiring washdown.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-20S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning, stepping up from smaller actuators if you need more force than micro-cylinders provide, or down from a 40 mm bore (which yields 628 N push at 0.5 MPa) to save space. The adjustable stroke is ideal for product changeovers, letting you set variable end stops on the fly. For holding a load without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock; you would need an external rod lock or a related SAIL cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 195 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet option. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load stress on the 12 mm rod is minimized, though external guides are still recommended for heavy lateral loads.
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 SAIJ32BX195-20S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, providing a usable travel window of 175-195 mm. It acts as a mechanical stop to fine-tune the end position without needing external stops.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
