About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-50
The AirTAC SAIJ100X150-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 150 mm nominal stroke by up to 50 mm. This creates a precise 100-150 mm usable travel window for fine-tuning end positions at commissioning without swapping out the cylinder or adding external stops. It delivers a robust 3927 N of push force at 0.5 MPa, making it suited for heavy positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. Mounting options cover the standard SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-50 Is Used
Product Changeover
Quickly adjust the 100-150 mm travel window during product size transitions on packaging lines without changing cylinder mounting.
Machine Setup
Fine-tune the retract end-position during initial commissioning to dial in exact stopping points for heavy 3927 N loads.
Variable End Stops
Use the 50 mm rear adjuster to create flexible end-stops for multi-format assembly stations requiring different stroke lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX150-50 the Right Cylinder?
Choose this 100 mm bore when your application requires high thrust, such as stepping down from a 125 mm bore that yields 6136 N at 0.5 MPa, or upgrading a 80 mm bore that provides 2513 N. The 50 mm adjustment range is ideal for product-size changeovers on a line, letting operators set variable end-stops on the fly. Remember that the rear adjuster acts only as a travel stop and deceleration aid; it does not hold the load without live air. For load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 150 mm stroke, 50 mm adjustment, PT G1/2 port, and the required mounting interface. Since the 150 mm stroke is below the 300 mm threshold, side-load concerns are minimal, but always ensure the M20x1.5 rod thread is properly aligned to prevent premature seal wear.
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 SAIJ100BX150-50 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 the maximum 1.0 MPa, it delivers up to 801 kgf.
The rear adjusting screw acts as a stopper that lets you shorten the effective stroke from the 150 mm nominal length down to 100 mm, giving a 100-150 mm usable travel window. The adjuster only sets the end position and does not lock the load without live air pressure.
