About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX750-10
The AirTAC SAIJ50X750-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a 750 mm nominal stroke and a 10 mm adjustment range, it provides a usable travel window of 740-750 mm. This bore delivers 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa, making it well-suited for moderate-load positioning tasks.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, though this unit is supplied without a magnet. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX750-10 Is Used
Product Changeover
Dial in the 740-750 mm travel window during format changes to accommodate slightly different package lengths without replacing the cylinder.
End-Stop Calibration
Fine-tune the retract position on a long conveyor diverter to ensure precise product alignment without adding external mechanical stops.
Commissioning Adjustment
Trim the 10 mm stroke during machine setup to perfectly sync the cylinder's end-of-stroke position with adjacent automation equipment.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX750-10 the Right Cylinder?
Choose this 50 mm bore cylinder when you need 982 N of push force at 0.5 MPa and require precise end-position tuning during commissioning without swapping out physical components. If your application demands less force, the 40 mm bore provides 628 N; if you need more power, the 63 mm bore offers 1559 N. The adjustable 740-750 mm window is ideal for accommodating minor product size variations on a line.
Because the 750 mm stroke is relatively long, an external guide is recommended to prevent rod side-loading and premature wear. For load-holding without continuous air pressure, this plain cylinder is insufficient since the rear adjuster is a travel stop rather than a lock; consider an AirTAC SAIL or BSAI model instead. To match this ISO 15552 replacement exactly, specify: 50 mm bore, 750 mm stroke, 10 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet.
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 SAIJ50BX750-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 750 mm nominal stroke by up to 10 mm, creating a 740-750 mm usable travel window. It sets the end position but does not lock the load without live air pressure.
