About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-50S
The AirTAC SAIJ32X190-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 140-190 mm, allowing you to dial back the 190 mm nominal stroke by up to 50 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push thrust and 345 N of pull thrust at 0.5 MPa.\n\nThis variant includes an integrated magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, and uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. It features PT tapered port threads (G1/8) and variable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on three sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-50S Is Used
Machine Changeover
Dial in the 140-190 mm travel window on the fly to accommodate different product sizes without physically replacing the cylinder.
End-Position Tuning
Fine-tune the retract stroke during initial setup to perfect positioning without machining external hard stops.
Assembly Line Conveyors
Use the 32 mm bore's 402 N push force to actuate stops and gates, adjusting the stroke as line layouts evolve.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-50S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when you need precise end-position tuning without swapping out components or adding external stops. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The rear adjuster acts solely as a travel stop to set the retract position; it does not hold the load without live air pressure. For positive load-holding, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 32 mm bore, 190 mm stroke, 50 mm adjustment, PT G1/8 port, and mounting interface. Since the 190 mm stroke is under 300 mm, side-load stress on the 12 mm rod is moderate, but 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 SAIJ32AX190-50S FAQ
The rear adjuster screw lets you shorten the 190 mm nominal stroke by up to 50 mm, creating a usable travel window of 140-190 mm. The adjuster functions as a mechanical stop and does not lock the load without air pressure.
At 0.5 MPa operating pressure, the SAIJ32X190-50-S provides 402 N of push force and 345 N of pull force. It operates at speeds between 30 and 800 mm/s.
