About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-50S
The AirTAC SAIJ32X65-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 15-65 mm usable travel window, allowing you to trim the 65 mm nominal stroke by up to 50 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups requiring precise end-position tuning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid is supplied via a PT G1/8 tapered port.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-50S Is Used
Product Changeovers
Dial in the 15-65 mm travel window on packaging lines to handle different carton sizes without physically replacing the actuator.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve exact sensor triggering using DMSE electronic switches.
Compact Assembly
Utilize the 32 mm profile footprint in tight electronics assembly stations where the SUS304 rod prevents corrosion.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX65-50S the Right Cylinder?
Choose this 32 mm bore when an application demands 402 N push force at 0.5 MPa but requires variable end-stops to accommodate product changeovers without swapping cylinders. If your setup needs less than 15 mm of travel, step down to a smaller fixed-stroke SAI unit; if you require higher force, the 40 mm bore yields 628 N at 0.5 MPa. The rear adjuster acts purely as a travel stop and does not hold the load without live air—use an external rod lock or SAIL cylinder for load-holding.
For ISO 15552 replacement matching, ensure you specify the 65 mm stroke, 50 mm adjustment range, PT G1/8 port, and the -S magnet option. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load stress on the 12 mm rod is minimal, though 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 SAIJ32BX65-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At a maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the 65 mm nominal stroke by up to 50 mm, creating a 15-65 mm usable travel window. It functions as a mechanical stop and does not lock the load without continuous air pressure.
