About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-40S
The AirTAC SAIJ100X375-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers a robust 3927 Newtons of push force and 3681 Newtons of pull force at 0.5 MPa, making it suitable for heavy-duty actuation. The integrated -S magnet enables position detection across the 375 mm stroke using CMSE reed and DMSE electronic solid-state sensors.
This model features a 40 mm adjustment range, creating a usable travel window between 335 and 375 mm. You can fine-tune the retract end-position directly at commissioning without adding external stops. The 25 mm carbon steel rod and M20x1.5 rod thread handle high side loads, while the extruded aluminum barrel incorporates variable air cushions at both ends to dampen impact.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-40S Is Used
Machine Changeover
Dial in the retract end-stop within the 335-375 mm window during product size changes without swapping out the entire cylinder assembly.
Material Diverting
Adjust the stroke on the fly to fine-tune the pusher distance for varying package widths on a high-speed packaging line.
Heavy-Duty Forming
Leverage the 3927 N push force at 0.5 MPa to press or form components, using the rear screw to set precise bottoming depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-40S the Right Cylinder?
Select this 100 mm bore cylinder when your application requires 3927 N of push force at 0.5 MPa, or up to 7068 N at 0.9 MPa. If your load demands less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas a 125 mm bore provides 6136 N for heavier setups. The 40 mm adjustment range is perfect for accommodating product size changeovers on a line, offering a 335-375 mm travel window. Because the nominal stroke is 375 mm, an external guide rail is recommended to prevent excessive side-loading on the extended rod.
For ISO 15552 dimensional interchangeability, verify the 100 mm bore, 375 mm stroke, 40 mm adjustment, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air. For fail-safe load holding, consider an external rod lock or the AirTAC SAIL and BSAI series.

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 SAIJ100X375-40S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 375 mm down to 335 mm. This creates a 40 mm adjustable window for fine-tuning the end position at commissioning without needing external stops.
At 0.5 MPa operating pressure, it provides 3927 Newtons of push force and 3681 Newtons of pull force. At the maximum 1.0 MPa pressure, the push force reaches 7068 Newtons.
