About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-30S
The AirTAC SAIJ100X65-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 35 to 65 mm. It delivers a robust 3927 N push force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet allows seamless operation with AirTAC CMSE reed and DMSE electronic sensors.
This adjustable-stroke model omits the FB, CA, CB, and CR mounts, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces. The rear adjustment screw acts purely as a travel stop for end-position tuning and does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-30S Is Used
Machine Changeover
Dial in the exact 35 to 65 mm end-stop during product size changes without physically swapping cylinders or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke at commissioning using the rear screw to perfectly time the 3927 N push force impact.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 1.0 MPa pressure rating for high-force positioning in washdown or corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX65-30S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 2513 N push force) is insufficient, or step down if the smaller bore's capacity is enough. An adjustable stroke is ideal for machine setup and product changeover, allowing you to fine-tune the end position without swapping the cylinder or adding external stops. To replace an ISO 15552 cylinder, match the 100 mm bore, 65 mm stroke, 30 mm adjustment, PT tapered ports, and the -S magnet. The 25 mm rod and M20x1.5 thread handle high side loads well, but even with a 65 mm stroke, always use an external guide for heavy 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 SAIJ100BX65-30S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 801 kgf.
The rear adjuster screw lets you shorten the 65 mm nominal stroke by up to 30 mm, creating a usable travel window of 35 to 65 mm. The adjuster functions only as a mechanical stop and does not hold the load without continuous air pressure.
