About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-50
The AirTAC SAIJ32X195-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 12mm SUS304 stainless steel rod. By turning the rear stopper screw, you can trim the effective travel down by up to 50mm, creating a highly versatile 145-195mm usable stroke window without swapping out hardware.
This bore size runs on G1/8 ports with a 27mm cushion length at both ends. The extruded aluminum barrel includes sensor grooves on both sides, and because this configuration uses a SUS304 rod, it handles minor exposure to moisture better than standard carbon steel. Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-50 Is Used
Product Changeovers
Dial in the 145-195mm travel window on the fly to accommodate different package sizes on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the retraction end position during initial commissioning to perfectly align a 402N push force against a delicate stop.
Variable End Stops
Use the rear adjuster to set precise deceleration points for repetitive assembly tasks, avoiding the need to bolt on external physical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-50 the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning during commissioning or frequent product changeovers, stepping up from smaller actuators if you need more force than a smaller bore provides, or stepping down from a 40mm bore (which yields 628N push at 0.5 MPa) to save space. The adjustable stroke is ideal when a fixed SAI cylinder would require external stops. To replace an ISO 15552 cylinder, match the 32mm bore, 195mm nominal stroke, 50mm adjustment range, PT tapered port threads, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Since the 195mm stroke is relatively short, side-load stress is minimal, but always guide the load externally for rigid mounting.
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 SAIJ32BX195-50 FAQ
The rear adjuster screw lets you shorten the nominal 195mm stroke by up to 50mm, providing an effective travel window of 145-195mm. This allows you to set the exact end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
