About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-75
The AirTAC SAIJ100X150-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 75 to 150 mm, allowing you to dial back the nominal 150 mm stroke by up to 75 mm during commissioning without adding external stops. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for heavy handling tasks.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-75 Is Used
Machine Changeover
Dial in the exact retract distance from 75 to 150 mm when switching product sizes on a packaging line, eliminating the need to swap cylinders for new formats.
Heavy Material Handling
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or chassis, using the rear stopper to safely trim the end-of-travel impact.
Washdown Equipment
Rely on the SUS304 stainless steel rod for corrosion resistance in food processing or chemical environments where standard carbon steel rods fail.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-75 the Right Cylinder?
Choose this 100 mm bore when you need significantly more force than the 80 mm version (2513 N push at 0.5 MPa) but want to avoid the bulk of a 125 mm cylinder. The adjustable stroke is ideal for product changeovers on a line, letting you fine-tune the retract end-position on the fly instead of physically swapping a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, verify the 150 mm stroke, 75 mm adjuster, PT G1/2 port, and the SUS304 rod material. Because the stroke is 150 mm, ensure your mounting setup adequately guides the load to prevent excessive side-load wear on the rod.
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 SAIJ100BX150-75 FAQ
At a 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 lets you shorten the effective travel from the nominal 150 mm down to 75 mm. This creates a 75-150 mm adjustable window for fine-tuning end positions at commissioning, but it acts only as a stop and does not lock the load without air pressure.
