About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-100S
The AirTAC SAIJ100X155-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 7068N of push force at 0.9 MPa. It features a SUS304 stainless steel rod and a built-in magnet for position sensing. The rear stopper mechanism allows you to trim the effective travel down by up to 100 mm, creating a highly flexible 55-155 mm usable stroke window for precise end-position tuning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine setup or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It uses a G1/2 port and omits the FB, CA, CB, and CR mounting styles found on some standard models, retaining Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-100S Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 55 and 155 mm during commissioning to accommodate different material thicknesses without changing the cylinder.
Product Size Changeover
Quickly readjust the rear stopper on a packaging or assembly line when switching to a new product format, minimizing machine downtime.
High-Force Clamping Setup
Leverage the 7068N push force at 0.9 MPa to securely clamp heavy workpieces while fine-tuning the clamping depth on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-100S the Right Cylinder?
Choose this 100 mm bore cylinder when an application demands high thrust (7068N push at 0.9 MPa) alongside variable end-stop positioning. If your setup requires less force, stepping down to an 80 mm bore yields 4523N push force at 0.9 MPa, but the SAIJ100X155-100-S is ideal when you need heavy pushing power within a 55-155 mm adjustable travel window. The wide 100 mm adjustment range is particularly useful for prototyping or lines running multiple product sizes.
Because the nominal stroke is 155 mm, side-load risks are moderate, but always ensure external guiding for optimal rod bearing life. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 dimensionally interchangeable cylinder, specify the 100 mm bore, 155 mm stroke, 100 mm adjustment, G1/2 PT ports, SUS304 rod, and the -S magnet.
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 SAIJ100BX155-100S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 55-155 mm, allowing you to fine-tune the end position without swapping the cylinder.
At 0.9 MPa operating pressure, the push force is 7068N and the pull force is 3681N. At 0.5 MPa, it provides 3927N of push force and 3681N of pull force.
