About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-100S
The AirTAC SAIJ100X150-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 50 to 150 mm, allowing you to dial back the nominal 150 mm stroke by up to 100 mm during commissioning. With a 100 mm bore, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa. The rod is constructed from SUS304 stainless steel, and the unit includes a magnet for position sensing.
This model uses PT tapered ports and is dimensionally interchangeable per ISO 15552. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air. For load-holding without air pressure, consider an external rod lock or pilot-operated check valve. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-100S Is Used
Variable End-Stop Tuning
Fine-tune the retract end position on packaging machines to accommodate different carton sizes without adding external physical stops.
Machine Changeover
Quickly adjust the effective stroke from 50 to 150 mm during product line changeovers to handle varying material lengths.
Assembly Press Setup
Dial in the exact travel window during initial commissioning of an assembly station to guarantee precise pressing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-100S the Right Cylinder?
Choose this 100 mm bore cylinder when your application requires 3927 N of push force at 0.5 MPa. If you need less force, the 80 mm bore offers 2513 N; if you need more, the 125 mm bore provides 6136 N. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without swapping cylinders. The SUS304 rod and M20x1.5 thread handle high side loads well, but for any stroke over 300 mm, an external guide is recommended to prevent rod deflection.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 150 mm stroke, 100 mm adjustment, PT port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The standard SAIJ is double-acting; for a fixed-stroke version, look at the standard SAI line.
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 SAIJ100BX150-100S FAQ
At an operating pressure of 0.5 MPa, 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 mechanically shorten the 150 mm nominal stroke by up to 100 mm, creating a usable travel window of 50 to 150 mm. The adjuster functions as a travel stop, not a lock, meaning the cylinder will not hold its load without continuous air pressure.
