Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 195mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40S
The AirTAC SAIJ32X195-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 155-195 mm usable travel window, allowing you to dial back the 195 mm nominal stroke by up to 40 mm during commissioning without swapping the cylinder. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it suited for lighter-duty precision tasks.
This variant includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, and because this is an -S model, it contains a magnet for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40S Is Used
Precision End-Stop Tuning
Dial in the exact 155-195 mm travel distance during machine commissioning to perfect positioning without adding external physical spacers.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on packaging lines when handling different product lengths, using the 40 mm rear adjustment screw.
Corrosive Environment Testing
Leverage the SUS304 stainless steel rod and standard sensor magnet to operate reliably in light-duty, humid testing chambers.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX195-40S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires fine end-position tuning or frequent product changeovers, stepping down from a 40 mm bore (628 N push at 0.5 MPa) if your force needs are minimal. The 40 mm adjustment window is ideal for dialing in exact end-stops on the fly rather than machining external spacers or reverting to a fixed-stroke SAI cylinder. If your process requires the load to be held mechanically without continuous air pressure, the SAIJ adjuster will not act as a brake; you would need to step over to an AirTAC SAIL (pneumatic lock) or BSAI (clamp-lock) cylinder. To match this ISO 15552 footprint, specify a 32 mm bore, 195 mm stroke, PT threads, and the -S magnet option.

- ✓ 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 SAIJ32BX195-40S 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 up to 724 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 195 mm down to as little as 155 mm, providing a 40 mm tuning window. It decelerates the travel end but does not lock or hold the load without live air pressure.
