About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-75
The AirTAC SAIJ100X165-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa, making it suitable for heavy-duty positioning. By turning the rear screw, you can trim the effective travel, creating a precise 90-165mm usable window to dial in final end positions without adding external stops.
This unit is configured with an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, PT tapered port threads, and operates without a magnet. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-75 Is Used
Product Changeover
Quickly adapt machinery for varying part lengths by shifting the retract stop within the 90-165mm window during line setup.
End-Position Tuning
Fine-tune the final retract position at commissioning to achieve exact placement without machining external stopper blocks.
Heavy Assembly Pressing
Leverage the 3927N push force at 0.5 MPa to seat heavy components, using the adjuster to limit over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-75 the Right Cylinder?
Choose this 100mm bore when a 63mm cylinder (providing 1559N push at 0.5 MPa) lacks the necessary thrust, but you want to avoid the larger 160mm class. The 75mm adjustment range is ideal for machines requiring significant product changeover flexibility, allowing you to shift the retract stop anywhere within the 90-165mm window rather than swapping a fixed-stroke SAI cylinder.
Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider a SAIL or BSAI cylinder. For ISO 15552 replacement matching, specify: 100mm bore, 165mm stroke, 75mm adjustment, PT G1/2 port, and no magnet. Because the stroke is under 300mm, side-load stress is minimal, but ensure the M20x1.5 rod thread is properly aligned during installation.
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 SAIJ100AX165-75 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 165mm stroke by up to 75mm, providing a usable travel range of 90-165mm. It only sets the travel end and does not lock the load without continuous air pressure.
