About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-40S
The AirTAC SAIJ100X165-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 165 mm nominal travel by up to 40 mm for a precise 125-165 mm usable window. It delivers substantial thrust, providing 3927 N of push force at 0.5 MPa and reaching 7068 N at 0.9 MPa. This bore size features a robust 25 mm piston rod and G1/2 ports with PT tapered threading.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and ships with a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-40S Is Used
Product Changeover
Quickly reconfigure the end-of-stroke position on packaging lines when switching to different container sizes, utilizing the 125-165 mm travel window.
Machine Setup
Fine-tune the final clamping position during equipment commissioning without machining new hard stops or disassembling the pneumatic circuit.
Variable End Stops
Dial in the precise extension distance for heavy-duty pressing operations requiring up to 7068 N of force at 0.9 MPa.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX165-40S the Right Cylinder?
Select this 100 mm bore when an 80 mm bore is insufficient, as the 80 mm variant only yields 2513 N of push force at 0.5 MPa compared to the 3927 N provided here. An adjustable stroke is ideal for machine setup and product changeover, letting you fine-tune the end position at commissioning without swapping the cylinder or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider the SAIL or BSAI series.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100 mm bore, 165 mm stroke, 40 mm adjustment range, G1/2 port with PT thread, and the -S magnet requirement. Because the 165 mm stroke is relatively long, ensure your mounting arrangement handles side loads; the 25 mm rod handles significant stress, but an external guide is recommended for unsupported loads.
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 SAIJ100AX165-40S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 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 allows you to shorten the 165 mm nominal stroke by up to 40 mm, creating a usable travel window of 125 to 165 mm. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
