About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-50S
The AirTAC SAIJ32X195-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore, delivering 402 N of push force and 345 N of pull force at 0.5 MPa. The integrated -50 mm adjustment screw allows you to trim the effective travel down from the 195 mm nominal stroke, creating a precise 145-195 mm usable positioning window without needing external stops.
This variant includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. Fitted with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves. The rear adjuster functions strictly as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-50S Is Used
Machine Changeover
Dial in the 145-195 mm stroke window rapidly during product size changes without swapping out the entire cylinder or adding mechanical shims.
End-Stop Calibration
Fine-tune the retract position at commissioning using the rear screw, ensuring precise alignment before locking down the setup.
Corrosive Testing Jigs
Leverage the SUS304 stainless steel rod for pilot testing in light chemical or washdown environments where carbon steel would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-50S the Right Cylinder?
Select this 32 mm bore model when an application requires exact end-position calibration during commissioning or product changeover, stepping up from smaller non-standard actuators while avoiding the bulk of a 40 mm bore (which provides 628 N push at 0.5 MPa). The adjustable 145-195 mm window is perfect for dialing in variable end stops on the fly. For load-holding without live air pressure, you must integrate an external pilot-operated check valve or select a different AirTAC series like SAIL or BSAI, as the SAIJ adjuster is only a stop. To guarantee a true ISO 15552 replacement, verify the 32 mm bore, 195 mm stroke, PT G1/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SAIJ32BX195-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 195 mm nominal stroke by up to 50 mm, providing a usable travel window of 145 to 195 mm. It only sets the end position and does not hold the load without continuous air pressure.
