About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-75S
The AirTAC SAIJ100X600-75-S is a double-acting ISO 15552 profile cylinder featuring a SUS304 stainless steel rod and an integrated rear stroke adjuster. It delivers 5497N of push force at 0.7MPa and provides a usable travel window of 525-600mm, letting you trim the effective stroke by up to 75mm during commissioning.
This bore uses a G1/2 port and includes a magnet for CMSE and DMSE sensors. The rear screw acts purely as a travel stop for end-position tuning, not a lock, while the extruded aluminum barrel retains standard ISO 15552 mounting dimensions.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-75S Is Used
Product Size Changeover
Dial in the 525-600mm travel window on the fly when adapting a packaging line to new carton dimensions without swapping hardware.
End-Position Tuning
Fine-tune the exact retract stop during machine commissioning to perfect a pressing or forming operation.
Long-Stroke Assembly
Leverage the 5497N push force at 0.7MPa for large-scale assembly tasks requiring a 600mm reach with precise end limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX600-75S the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (3518N push at 0.7MPa) lacks thrust or a 125mm bore is excessive. The 75mm adjustment window is ideal for product-size changeovers, replacing fixed-stroke SAI cylinders when external stops are impractical. To match this ISO 15552 cylinder, specify 100mm bore, 600mm stroke, PT ports, and the -S magnet.
Because the stroke is 600mm, the M20x1.5 rod needs external guiding to prevent excessive side loading. Note that the rear adjuster and air cushions only decelerate the load; for position holding without live air, use a SAIL or BSAI lock 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 SAIJ100BX600-75S FAQ
At 0.7MPa it provides 5497N of push force and 3681N of pull force. The maximum force is 801kgf at 1.0MPa, and the operational speed range is 30-800mm/s.
The rear adjuster screw lets you shorten the 600mm nominal stroke by up to 75mm, creating a 525-600mm usable travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
