About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-10S
The AirTAC SAIJ100X150-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 140 to 150 mm for precise end-position tuning. Built with a SUS304 stainless steel rod and a magnet for position sensing, it delivers a robust 3927 N push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This adjustable-stroke model allows you to fine-tune the retract position at commissioning without swapping out the entire cylinder or adding external stops. It features PT tapered ports and supports AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster functions strictly as a travel stop to set the stroke end, not as a lock, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-10S Is Used
End-Position Tuning
Dial in the exact 140 to 150 mm retract distance during machine commissioning to accommodate minor mechanical variations without disassembling the assembly.
Product Changeover
Quickly adjust the stroke end by up to 10 mm when switching between slightly different product sizes on a packaging line, minimizing downtime.
Heavy-Duty Forming
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks while using the rear stopper to prevent over-travel on delicate workpieces.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust, such as the 3927 N push force at 0.5 MPa, combined with a 10 mm adjustable end-stop for product changeovers. If your setup needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas larger loads might require a 125 mm bore providing 6136 N. Because the stroke is 150 mm, side-load risks are moderate, but always ensure proper external guiding for optimal rod life.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 150 mm stroke, PT port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. For applications requiring true load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
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 SAIJ100BX150-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 150 mm stroke by up to 10 mm, creating a 140 to 150 mm usable travel window. It only sets the end position and does not lock the load without live air.
