About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX750-10S
The AirTAC SAIJ50X750-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a SUS420J2 stainless steel rod and a built-in magnet for position sensing. By turning the external stopper, you can fine-tune the effective travel down from the 750 mm nominal stroke, providing a precise 740-750 mm usable window to dial in end positions during commissioning.
Delivering 982 N of push force and 825 N of pull force at 0.5 MPa, this 50 mm bore profile cylinder integrates variable air cushions at both ends to decelerate the motion. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed and DMSE solid-state switches. The PT tapered port threads ensure a tight, reliable pneumatic connection.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX750-10S Is Used
Machine Setup & Changeover
Dial in the 740-750 mm travel window during product format changes without physically replacing the cylinder or adding external stop blocks.
Variable End-Stop Positioning
Fine-tune the retract distance on a long-stroke conveyor diverter to accommodate varying package sizes on the fly.
Commissioning Calibration
Trim up to 10 mm of stroke during initial machine commissioning to perfectly time the 982 N thrust contact point against a workpiece.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX750-10S the Right Cylinder?
Choose this adjustable-stroke model when a process requires exact end-position tuning without swapping out the entire cylinder or adding external mechanical stops. If the application needs slightly less force, the 40 mm bore offers 628 N push at 0.5 MPa; if more thrust is required, the 63 mm bore provides 1559 N. Because the 750 mm stroke is long, an external guide rail is recommended to prevent excessive side-loading on the 20 mm rod thread.
For drop-in interchangeability, match the 50 mm bore, 750 mm stroke, 10 mm adjustment range, PT port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series.
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 SAIJ50 Adjustable Cylinder SAIJ50AX750-10S FAQ
It features an external adjusting screw at the rear that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 740 to 750 mm, which is ideal for fine-tuning end positions during setup.
At 0.5 MPa operating pressure, it provides 982 N of push force and 825 N of pull force. The -S option includes a piston magnet for use with AirTAC CMSE reed switches and DMSE solid-state electronic sensors.
