About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-50S
The AirTAC SAIJ32X50-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 0 to 50 mm, letting you dial back the full 50 mm nominal stroke to exactly match your machine's end-stop requirements.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for CMSE reed and DMSE electronic sensors. It uses a PT G1/8 tapered port and relies on variable air cushions at both ends to decelerate the load, though it will not hold a position without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-50S Is Used
Machine Changeover
Quickly adjust the 0-50 mm travel window during product size changes on a packaging line without replacing the cylinder or bolting on external stops.
End-Stop Calibration
Fine-tune the exact retracted end position during machine commissioning to prevent crashes and ensure precise parts placement.
Variable End Positioning
Set custom retraction limits on the fly for testing and assembly fixtures, using the rear stopper to define the exact travel distance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX50-50S the Right Cylinder?
Select this 32 mm bore cylinder when an application requires precise end-position tuning at commissioning without swapping hardware or adding external stops. If your process needs greater thrust, stepping up to the 40 mm bore yields 628N of push force at 0.5 MPa. For load-holding without continuous air pressure, this adjuster-only design will not suffice; consider the SAIL lock or BSAI clamp-lock series instead.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using a reduced set of accessories: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for any stroke of 300 mm or more, an external guide is recommended to prevent rod deflection.

- ✓ 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 SAIJ32BX50-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. It can deliver up to 724N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 50 mm. This gives the 50 mm nominal stroke a usable travel window of 0 to 50 mm, allowing precise end-position tuning without live air holding the load.
