About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-75S
The AirTAC SAIJ32X190-75-S is a double-acting ISO 15552 profile cylinder with a rear mechanical stopper that shortens the effective travel. It provides a usable stroke window of 115-190 mm, allowing precise end-position tuning during commissioning without swapping the barrel. In the 32 mm bore class, it generates 563 N of push force and 345 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel carries sensor grooves on both sides, and the standard PT G1/8 porting keeps the ISO 15552 footprint intact.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-75S Is Used
End-Position Tuning
Dial in the exact retract distance between 115 and 190 mm during machine setup to perfect part ejection without changing hardware.
Product Changeover
Quickly alter the effective stroke on automated lines when switching to a different product size or format.
Variable Stop Assembly
Use the rear stopper to define precise end positions for pressing or locating tasks within the 32 mm force class.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-75S the Right Cylinder?
Choose this 32 mm bore when your application needs 563 N of push force at 0.7 MPa. If you require less force, a smaller option lacks this bore's capacity; if you need more thrust, stepping up to a 40 mm bore yields 879 N at the same pressure. The 75 mm adjustment range is ideal for product changeovers where the end-stop varies, replacing the need to bolt on external stops. For holding loads without live air, select a SAIL or BSAI cylinder instead, as this rear adjuster is a travel stop, not a lock. To match this ISO 15552 replacement exactly, specify: 32 mm bore, 190 mm stroke, 75 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and an -S magnet.
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 SAIJ32AX190-75S FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder produces 563 N of push force and 484 N of pull force. It operates at speeds of 30-800 mm/s.
The rear adjuster acts as a travel stop that lets you mechanically shorten the stroke from 190 mm down to as little as 115 mm. It only sets the end position and does not lock the load without live air pressure.
