About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-40
The AirTAC SAIJ100X600-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 560 to 600 mm. Built with a SUS304 stainless steel rod and PT tapered ports, it generates 3927 N of push force at 0.5 MPa and reaches a maximum of 801 kgf at 1.0 MPa. This bore size features a robust 25 mm rod and M20x1.5 thread, paired with 36 mm air cushions at both ends to manage high kinetic energy.
Instead of relying on fixed stops, the external rear screw lets you fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. The adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-40 Is Used
Product Changeover
Dial in the 560-600 mm travel window during format changeovers to accommodate different product lengths without replacing the actuator.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve precise seating of heavy components, utilizing the 40 mm adjustment range.
Assembly Line Setup
Secure heavy fixtures with 3927 N of push force at 0.5 MPa while making on-the-fly adjustments to the end stop for varying assembly tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-40 the Right Cylinder?
Choose this 100 mm bore when an 80 mm cylinder's 2513 N push force at 0.5 MPa is insufficient, but you want to avoid the larger footprint of a 125 mm option. An adjustable stroke is ideal for machinery requiring precise end-position tuning during setup or when accommodating slight product size variations on a line, offering flexibility that a fixed-stroke SAI cylinder cannot. To replace an existing ISO 15552 cylinder, match the 100 mm bore, 600 mm stroke, PT ports, and mounting style.
Because this cylinder features a 600 mm stroke, the extended 25 mm rod is subject to increased side-loading risks. An external guide mechanism is recommended to prevent rod deflection and premature seal wear under heavy loads. Remember that the rear adjuster only sets the travel end; for load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI series cylinder.
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 SAIJ100BX600-40 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At its maximum operating pressure of 1.0 MPa, it delivers up to 801 kgf of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 560 to 600 mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
