About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100S
The AirTAC SAIJ100X650-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 550 to 650 mm. It delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, utilizing a standard carbon steel rod with PT tapered ports. The extruded aluminum barrel features sensor grooves on both sides, and mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100S Is Used
Product Changeover
Dial in the exact 550-650 mm end stop during format size changes on a packaging line without swapping the actuator.
Heavy Press Fit
Leverage the 3927 N push force at 0.5 MPa to seat heavy components, fine-tuning the travel limit to prevent over-travel.
Machine Setup
Commission long-stroke machinery safely by trimming the rear stopper to match the exact mechanical collision point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X650-100S the Right Cylinder?
Choose this 100 mm bore when the 80 mm class (2513 N push at 0.5 MPa) is insufficient, or step down if the 63 mm class (1559 N) is adequate. The 100 mm adjustment range is ideal for product changeovers, allowing you to dial in the exact end position without adding external stops. For a fixed end position, a standard SAI cylinder is simpler.
Because the nominal stroke is 650 mm, the 25 mm rod requires external guidance to prevent excessive side loading. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100X650-100S FAQ
At 0.5 MPa it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster allows you to shorten the effective travel by up to 100 mm, creating a 550 to 650 mm usable window. It functions as a mechanical stop and does not lock the load without air pressure.
