About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-100S
The AirTAC SAIJ100X200-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 100 to 200 mm. Built with a SUS304 stainless steel rod, it delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks. The integrated magnet supports position sensing.
This adjustable-stroke design allows operators to fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder or adding external stops. The rear screw acts purely as a travel stop and works alongside standard variable air cushions at both ends to decelerate the load. It does not lock or hold the load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-100S Is Used
Product Changeover
Quickly dial in the 100-200 mm stroke window during packaging line format changes to accommodate different box sizes without mechanical rebuilds.
Variable End Stops
Ideal for machining fixtures where the rear stopper fine-tunes the clamping position on the fly, ensuring precise placement without external hard stops.
Machine Setup
Streamlines initial equipment commissioning by allowing technicians to set the exact retract distance mechanically, reducing the need for PLC reprogramming.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-100S the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application requires substantial force—such as the 5497 N push force at 0.7 MPa—combined with a highly flexible end-position window. If you need less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The 100 mm bore features a G1/2 port, PT tapered threads, and operates at speeds of 30-800 mm/s. Because the nominal stroke is 200 mm, an external guide is recommended to manage side loads on long extensions.
The -S magnet enables precise end-of-stroke detection using AirTAC CMSE reed or DMSE electronic solid-state sensors. When replacing an ISO 15552 cylinder, match the 100 mm bore, 200 mm stroke, 100 mm adjustment, G1/2 PT port, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For applications requiring true load-holding without live air, consider the SAIL or BSAI variants instead of relying on the adjuster stop.
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 SAIJ100BX200-100S 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 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to trim the effective stroke by up to 100 mm, creating a usable travel window of 100 to 200 mm. It functions as a mechanical stop to set the end position and does not lock the load without air pressure.
