About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-30
The AirTAC SAIJ100X165-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 135 to 165 mm, allowing you to dial back the nominal 165 mm stroke by up to 30 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it is built for substantial actuation tasks.
This unit utilizes a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and features PT (tapered) G1/2 ports. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-30 Is Used
Product Changeovers
Dial in the 135-165 mm travel window on the fly to accommodate varying product lengths without physically swapping cylinders or reworking machine stops.
End-Position Tuning
Fine-tune the retract end position during machine commissioning using the rear adjuster, eliminating the need for custom spacer rings or external mechanical stops.
Heavy-Duty Clamping
Leverage the 3927 N push force at 0.5 MPa for robust clamping and pressing tasks, adjusting the stroke depth precisely for different material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-30 the Right Cylinder?
Choose this 100 mm bore when a 80 mm cylinder (2513 N push at 0.5 MPa) lacks thrust, but stepping up to 125 mm (6136 N) would be excessive. The 30 mm adjustment range is ideal for product changeovers, letting you fine-tune the end position without adding external stops or swapping the cylinder.
Because the stroke is 165 mm, the 25 mm rod and M20x1.5 thread handle side loads well, though an external guide is recommended for heavy lateral forces. Remember that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold loads without live air. For position holding, consider SAIL or BSAI cylinders. To replace an ISO 15552 unit, match the 100 mm bore, 165 mm stroke, 30 mm adjust, PT G1/2 port, and mounting footprint.
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 SAIJ100AX165-30 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 the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear external stopper screw allows you to shorten the effective travel from the 165 mm nominal stroke down to as little as 135 mm. This creates a 135-165 mm adjustable window for fine-tuning the end position at commissioning without changing the cylinder.
