Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-20
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 90mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-20
The AirTAC SAIJ100X90-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 70-90 mm usable travel window by allowing you to trim up to 20 mm off the 90 mm nominal stroke. Delivering 3927 N of push force at 0.5 MPa, it handles demanding positioning tasks with precision.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a G1/2 port and a robust 25 mm carbon steel rod with an M20x1.5 thread. The rear stopper sets the retract end position, but it acts purely as a travel stop and does not lock the load without continuous air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-20 Is Used
End-Position Tuning
Dial in the exact retract distance within the 70-90 mm window during machine commissioning to perfect part seating without machining new hard stops.
Product Changeover
Quickly adjust the stroke by up to 20 mm on the rear screw when switching the production line to a different sized component.
High-Force Clamping
Leverage the 3927 N push force at 0.5 MPa to securely clamp heavy workpieces while using the adjuster to set the exact clamping depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X90-20 the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder lacks thrust; an 80 mm bore yields 2513 N at 0.5 MPa, whereas this SAIJ100X90-20 provides 3927 N. The adjustable stroke is ideal for machine setup and product changeovers, letting you fine-tune the end position at commissioning without swapping the cylinder or adding external stops. For holding a load without live air, consider an external rod lock or the AirTAC SAIL lock variant.
To replace an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 20 mm adjustment, G1/2 PT port, and mounting style. Available mounts include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since this is a non-magnet model, add an -S suffix if you require CMSE reed or DMSE electronic 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 SAIJ100X90-20 FAQ
A rear external screw acts as a stopper, allowing you to shorten the effective travel by up to 20 mm. This creates a 70-90 mm adjustable window, but the screw is a travel stop, not a lock, and cannot hold the load without air pressure.
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At 0.7 MPa, the push force increases to 5497 N.
