About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-100
The AirTAC SAIJ100X375-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 275-375 mm usable travel window by trimming the 375 mm nominal stroke up to 100 mm via an external stopper screw. In the 100 mm bore class, it generates 3927 N of push force and 3681 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for direct switch mounting.
This model uses a G1/2 port and a 25 mm carbon steel rod with an M20x1.5 thread. The larger rod diameter handles higher side loads, though the 375 mm stroke still requires an external guide to prevent rod bending. It supports speeds of 30-800 mm/s and uses adjustable air cushions at both ends to decelerate the payload.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 275-375 mm window during machine commissioning without adding external stops.
Product Size Changeover
Quickly adapt the cylinder stroke on packaging lines when transitioning to a different product size.
Heavy Payload Handling
Move substantial loads using the 3927 N push force while relying on the adjustable air cushions for smooth deceleration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X375-100 the Right Cylinder?
Choose this 100 mm bore if the 80 mm bore (2513 N push at 0.5 MPa) is insufficient, or step down to the 80 mm if 3927 N is excessive. The adjustable stroke is ideal for machine setup and product changeover, allowing you to fine-tune the retract end position without swapping hardware. For load-holding without live air pressure, select a SAIL or BSAI cylinder, as the rear adjuster here is a travel stop, not a lock.
To match this ISO 15552 interchangeable cylinder, specify a 100 mm bore, 375 mm stroke, 100 mm adjustment, G1/2 PT port, and your required mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the stroke is over 300 mm, ensure your design incorporates an external guide to manage side loads.
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 SAIJ100X375-100 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force reaches 7068 N.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, you can trim the 375 mm nominal stroke back by up to 100 mm, giving a usable travel window of 275-375 mm.
