About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-30S
The AirTAC SAIJ100X650-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 620-650 mm usable travel window, allowing you to dial back the 650 mm nominal stroke by up to 30 mm during machine commissioning. Delivering 3927 N of thrust at 0.5 MPa, it handles heavy positioning tasks without needing external stops.
This model includes a standard -S magnet for position sensing and is fully compatible with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides, and the M20x1.5 rod thread pairs with a 25 mm rod to handle high side loads effectively.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-30S Is Used
Machine Changeover
Fine-tune the 620-650 mm end position during product size transitions without physically replacing the cylinder or adding external mechanical stops.
Heavy Material Handling
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or workpieces, using the adjustable stop to set precise indexing distances.
Automated Assembly Press
Dial in the exact retraction point during commissioning to accommodate different part heights, relying on the 25 mm rod for robust operation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-30S the Right Cylinder?
Select this 100 mm bore when a 63 mm cylinder's 1559 N push force at 0.5 MPa is insufficient for your tooling payload. The adjustable rear stopper is ideal for product changeovers, letting you fine-tune the end position without swapping the cylinder. Remember that the rear adjuster acts only as a travel stop; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI series cylinder.
Because the 650 mm stroke is relatively long, always use an external guide rail to prevent rod binding under heavy loads. This SAIJ model uses a PT tapered G1/2 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces. It is dimensionally interchangeable per ISO 15552, matching standard mounting footprints.
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 SAIJ100X650-30S FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N. The operational speed range for this 100 mm bore is 30-800 mm/s.
The rear adjuster screw allows you to shorten the effective travel from the 650 mm nominal stroke by up to 30 mm, creating a 620-650 mm usable window. It functions purely as a mechanical stop and does not lock the load without live air pressure.
