About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X550-10S
The AirTAC SAIJ100X550-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100mm bore and a 550mm nominal stroke, yielding a usable travel window of 540 to 550mm. This 10mm fine-tuning range allows you to dial in the exact retract end-position during commissioning without swapping hardware. In the 100mm bore class, it delivers 3927N of push force and 3681N of pull force at 0.5MPa.
This unit includes a magnet for position sensing, operating reliably with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves. The carbon steel piston rod features an M20x1.5 thread, and the cylinder uses PT tapered ports (G1/2). It relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X550-10S Is Used
Precision End-Stop Tuning
Dial in the exact 540-550mm retract position during machine commissioning to achieve precise seating forces without adding external stopper hardware.
Product Size Changeover
Quickly adapt a packaging line to different carton depths by trimming the stroke up to 10mm, accommodating product variations on the fly.
Heavy Assembly Pressing
Leverage the 3927N push force at 0.5MPa to seat heavy components, using the fine adjustment to control the final resting position precisely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X550-10S the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder lacks thrust; an 80mm bore provides 2513N push at 0.5MPa, whereas this SAIJ100X550-10-S delivers 3927N at the same pressure. The adjustable stroke is ideal for applications requiring variable end-stops or product changeovers, providing a 540-550mm travel window. For a fixed end-position without the need for commissioning tweaks, a standard SAI cylinder is sufficient. To match this ISO 15552 replacement exactly, specify: 100mm bore, 550mm stroke, 10mm adjustment, PT port thread, carbon steel rod, and the -S magnet option.
Because the nominal stroke is 550mm, the M20x1.5 rod is subject to increased side-loading leverage; an external guide rail should be used to prevent rod binding. Remember that the rear adjuster is a travel stop, not a lock—the cylinder cannot hold a load without live air pressure. 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 SAIJ100X550-10S FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke within a 540-550mm window. It sets the travel end and relies on the air cushion for deceleration, but it does not lock or hold the load without continuous air pressure.
