About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-10S
The AirTAC SAIJ100X375-10-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a 365 to 375 mm usable travel window, allowing you to dial back the nominal 375 mm stroke by up to 10 mm during commissioning. This bore delivers substantial thrust, pushing 7068 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
Equipped with a standard carbon steel rod and a -S magnet, the barrel features dual sensor grooves for direct mounting of CMSE reed or DMSE electronic solid-state switches. The M20x1.5 rod thread and 25 mm rod diameter handle high side loads well, but because the stroke is 375 mm, you should pair it with an external guide to prevent rod binding. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and PT tapered ports.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-10S Is Used
Machine Setup & Changeover
Fine-tune the end-stop by up to 10 mm during product size transitions without disassembling the tooling or adding external shims.
Variable End-Stop Positioning
Dial in the exact 365 to 375 mm travel window required for diverter arms and heavy-duty material placement on automated lines.
Heavy-Duty Assembly Pressing
Leverage the 7068 N push force at 0.9 MPa to seat large components, adjusting the final 10 mm of travel to accommodate varying part tolerances.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-10S the Right Cylinder?
Select this 100 mm bore when a 50 mm bore (offering 1767 N push at 0.9 MPa) is insufficient for your tooling payload. Choose the SAIJ adjustable-stroke variant over a fixed SAI cylinder when you need precise end-position tuning during machine setup or product changeover without swapping the physical cylinder. To replace an ISO 15552 cylinder, match the 100 mm bore, 375 mm stroke, 10 mm adjuster, PT port thread, and -S magnet requirement.
Because the stroke is 375 mm, an external guide is recommended to support the load and prevent side-load wear on the rod seals. 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 true load-holding, use an external rod lock, a pilot-operated check valve, or select the SAIL or BSAI series cylinders.
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 SAIJ100X375-10S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder generates a push force of 7068 N and a pull force of 3681 N. The maximum theoretical push force at 1.0 MPa is 801 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 375 mm down to 365 mm. This provides a 10 mm tuning window for precise end-position calibration without replacing the cylinder.
