About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-10
The AirTAC SAIJ100X750-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 3927N of push force at 0.5 MPa and utilizes a G1/2 port with a 25mm carbon steel rod. The integrated rear stopper allows you to fine-tune the effective travel within a 740-750mm window, providing exact end-position control during commissioning without adding external stops.
This extruded aluminum barrel design includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. It supports a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-10 Is Used
Machine Setup Tuning
Dial in the exact 740-750mm retract position during machine commissioning without swapping cylinders or machining external stopper blocks.
Product Changeover
Quickly adjust the end-stop for varying package sizes on a processing line by turning the rear screw during product transitions.
Long-Stroke Clamping
Provide 3927N of clamping force at 0.5MPa over a 750mm reach, fine-tuning the final 10mm of travel to suit varying material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X750-10 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (2513N push at 0.5MPa) lacks thrust, but a 125mm bore (6136N) is oversized. The 10mm adjustment window is ideal for dialing in exact retract positions during product changeovers. For load-holding without live air, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
When replacing an ISO 15552 cylinder, match the 100mm bore, 750mm stroke, PT tapered port threads, and the chosen mounting. Because the 750mm stroke is long, the 25mm rod and M20x1.5 thread handle substantial side loads, but an external guide is still recommended to prevent rod binding.
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 SAIJ100X750-10 FAQ
At 0.5 MPa, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 10mm, creating a 740-750mm usable window. It sets the end position but does not lock the load without live air.
