About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-100S
The AirTAC SAIJ100X750-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It provides a nominal 750 mm stroke that can be dialed back by up to 100 mm, creating a precise 650-750 mm usable travel window for exact end-position tuning during commissioning. In the 100 mm bore class, it generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, with a robust 25 mm piston rod and M20x1.5 rod thread handling high side loads.
This configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments. Variable air cushions at both ends absorb kinetic energy across its 30-800 mm/s speed range.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-100S Is Used
Product Changeovers
Dial in the 650-750 mm travel window on the fly to accommodate varying package lengths without disassembling the pneumatic setup.
Adjustable Diverters
Fine-tune the actuator end-stop position precisely during machine commissioning to align product routing gates perfectly.
Long-Stroke Assembly
Leverage the 3927 N push force and SUS304 rod to drive large jigs over a 750 mm span while adjusting the final press position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-100S the Right Cylinder?
Choose this 100 mm bore adjustable cylinder when your machine requires 3927 N of push force at 0.5 MPa and you need to trim the end-of-travel position without swapping physical components. The 100 mm rear adjuster screw allows you to shorten the effective stroke anywhere within the 650-750 mm window, which is ideal for product changeovers or dialing in a precise stopping distance. If your application requires less force, the 80 mm bore neighbor provides 2513 N; if you need more, the 125 mm bore offers 6136 N.
Because the 750 mm stroke is long, the 25 mm rod and M20x1.5 thread still need external guidance to prevent excessive side loading on the piston. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration—neither will hold a load without live air pressure. For fail-safe load holding, select a SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To replace an ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, 100 mm adjustment, PT G1/2 port, and the -S 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 SAIJ100 Adjustable Cylinder SAIJ100BX750-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, the push force increases to 801 kgf.
The rear adjuster acts as an external stop that lets you shorten the 750 mm nominal stroke by up to 100 mm, providing a usable 650-750 mm travel window. It sets the end position but does not lock the load without live air pressure.
