About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-50
The AirTAC SAIJ32X95-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This yields a highly flexible usable travel window of 45 to 95 mm, letting you dial in exact end positions during commissioning without swapping out the barrel or adding bulky external stops. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop and relies on the variable air cushions at both ends to decelerate the load; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-50 Is Used
Machine Changeovers
Rapidly reconfigure the 45-95 mm travel window during product size changeovers without disassembling the cylinder assembly.
End-Position Tuning
Fine-tune the retract end-position at commissioning to perfect a 402 N push motion without adding external mechanical stops.
Variable Stops on Lines
Adjust the stroke on the fly for conveyor diverters or sorting arms that handle multiple package sizes on a single line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX95-50 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and a highly variable end-of-stroke position. If your setup needs less force, stepping down to a 25 mm bore (if available) might suffice, but stepping up to a 40 mm bore yields 628 N of push force for heavier payloads. The 50 mm adjustment range on this 95 mm stroke is exceptionally wide, making it ideal for product-size changeovers on a packaging line where the rear stopper must frequently shift the 45-95 mm travel window.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 95 mm stroke, 50 mm adjustment, PT port threads, and SUS304 rod material. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the rear adjuster is a stop and not a lock, it will not hold a load without live air; for true fail-safe holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder.

- ✓ 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 SAIJ32BX95-50 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 801 N of push force.
The rear adjuster screw lets you shorten the 95 mm nominal stroke by up to 50 mm, creating a usable travel window of 45 to 95 mm. The adjuster acts as a mechanical stop to set the end position and is not a lock, meaning it will not hold the load without continuous air pressure.
