About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-30S
The AirTAC SAIJ100X145-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, letting you trim the nominal 145 mm travel back by up to 30 mm for a usable 115-145 mm window. It delivers 5497 N of push force at 0.7 MPa and pulls 3681 N. The extruded aluminum barrel features dual sensor grooves for position feedback.
This SKU is built with a SUS420J2 stainless steel rod (option A) for corrosion resistance and uses PT tapered ports. You can mount AirTAC CMSE reed or DMSE electronic sensors directly. The rear stopper fine-tunes end positions at commissioning, but it is a travel stop, not a lock—use SAIL or BSAI cylinders if you need to hold loads without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-30S Is Used
Product Changeovers
Dial in the 115-145 mm travel window during line changeovers to accommodate different package sizes without replacing the cylinder.
End-Position Tuning
Fine-tune the retract end position at machine commissioning using the rear screw, avoiding the need for custom external mechanical stops.
Assembly Press Setup
Set precise engagement depths on the fly, leveraging the 5497 N push force for pressing operations while retaining flexibility.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX145-30S the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short (80 mm yields 3518 N push at 0.7 MPa) or 125 mm is overkill. The 30 mm adjustment window is ideal for product changeovers, letting you dial in the exact end position without bolting on external stops or swapping a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify bore 100, 145 mm stroke, 30 mm adjust, PT ports, and the -S magnet.
At 145 mm stroke, side-load risks are low, but always guide the load for smooth operation. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting FB, CA, CB, and CR. The 25 mm rod and M20x1.5 thread handle high side loads well.
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 SAIJ100AX145-30S FAQ
At 0.7 MPa, this 100 mm bore cylinder provides 5497 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 145 mm nominal stroke by up to 30 mm, creating a 115-145 mm usable travel window. It acts as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
