About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-10
The AirTAC SAIJ100X145-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 10 mm of end-position trimming. This creates a usable travel window of 135 to 145 mm, allowing precise calibration during commissioning without adding external stops. It delivers a robust 3927 N of push force at 0.5 MPa and uses a G1/2 port to drive its 100 mm bore.
This variant incorporates a SUS420J2 stainless steel rod for enhanced durability against moisture and minor corrosion. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later. The rear adjuster acts purely as a travel stop to set deceleration limits and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-10 Is Used
End-Position Calibration
Dial in the exact retract distance within a 135-145 mm window during machine commissioning to perfect product placement without physical spacers.
Machining Setup
Micro-adjust the tooling stroke on machining fixtures to compensate for tool wear or material thickness variations.
Product Changeover
Quickly adapt a packaging line's reject arm stroke by up to 10 mm to handle varying carton sizes on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-10 the Right Cylinder?
Choose this 100 mm bore when a 50 mm bore (982 N at 0.5 MPa) is insufficient but a 125 mm bore (6136 N) would be excessive overkill. The 10 mm adjustment range is ideal for applications requiring micro-adjustments to the retract position during machine setup or product changeover, rather than swapping to a fixed-stroke SAI cylinder. When matching an ISO 15552 replacement, verify the 145 mm stroke, 10 mm adjuster, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 145 mm, side loads are minimal, but long unsupported strokes still require an external guide.
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 SAIJ100AX145-10 FAQ
At a 0.5 MPa operating pressure, the 100 mm bore provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
A rear stopper screw allows you to shorten the effective travel by up to 10 mm. This creates a 135-145 mm usable stroke window for fine-tuning end positions at commissioning. The adjuster is a mechanical stop, not a lock, and requires live air to hold the load.
