About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-10
The AirTAC SAIJ100X375-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 365-375 mm usable travel window, letting you dial in the retract end-position precisely during commissioning without adding external stops. In the 100 mm bore class, it delivers a robust 7068 N push force at 0.9 MPa.
This extruded aluminum barrel unit includes a 25 mm carbon steel piston rod with an M20x1.5 thread, designed to handle substantial side loads. It uses a PT tapered G1/2 port and includes variable air cushions at both ends. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-10 Is Used
Machine Setup Tuning
Dial in the exact 365-375 mm retract position during initial machine commissioning without swapping out physical spacer shims.
Product Changeover
Quickly adjust the end-stop by up to 10 mm to accommodate slightly different product sizes on the same conveyor line.
Heavy Load Positioning
Leverage the 7068 N push force to move heavy pallets or fixtures while fine-tuning the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-10 the Right Cylinder?
Select this 100 mm bore model when an application requires high thrust—7068 N at 0.9 MPa—and a 375 mm stroke with fine-tuning capabilities. If your setup needs less force, the 80 mm bore offers 4523 N at 0.9 MPa. The 10 mm rear adjuster is ideal for variable end-stops during product changeovers. Because the stroke is 375 mm, an external guide is recommended to prevent rod side-load wear.
For an exact ISO 15552 replacement, match the 100 mm bore, 375 mm stroke, 10 mm adjustment, PT G1/2 port, and carbon steel rod. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For load-holding, consider the SAIL or BSAI series.
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 SAIJ100X375-10 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder provides 7068 N of push force and 3681 N of pull force. At 0.5 MPa, it provides 3927 N push and 3681 N pull.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 10 mm, creating a 365-375 mm usable travel window. It only sets the end position and does not lock or hold the load without continuous air pressure.
