About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-100
The AirTAC SAIJ100X170-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 70 to 170 mm usable travel window. Delivering 5497 N of push force at 0.7 MPa, it handles substantial loads while allowing precise end-position tuning during commissioning. This model uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads.
Equipped with a G1/2 port and a 25 mm rod, it carries high side-load capacity compared to smaller bores. The rear adjustment screw acts purely as a travel stop to fine-tune the retract position without needing external stops. It supports mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-100 Is Used
Variable End Stops
Dial in the exact retract distance for multi-format packaging lines, trimming the nominal 170 mm stroke down to 70 mm as needed.
Machine Changeover
Quickly adapt actuator endpoints during product size changes without physically swapping the cylinder or adding mechanical spacers.
Heavy Assembly Pressing
Leverage the 5497 N push force at 0.7 MPa to seat heavy components, using the fine adjustment to control the final pressing depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-100 the Right Cylinder?
Choose this 100 mm bore when 50 mm bores (1374 N push at 0.5 MPa) lack the necessary thrust, but an 80 mm bore is still insufficient. The 100 mm adjustment range is ideal for machines requiring significant product-size changeovers. Because the stroke is 170 mm, an external guide is recommended for unsupported loads. For load-holding without live air, use a SAIL or BSAI cylinder, as the SAIJ adjuster is a stop, not a lock.
To replace an ISO 15552 cylinder, match the 100 mm bore, 170 mm stroke, 100 mm adjustment, G1/2 PT ports, and the desired mounting. Note this SKU lacks a magnet; adding -S enables CMSE reed or DMSE electronic sensors.
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 SAIJ100BX170-100 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 N of push force and 5180 N of pull force. At 0.5 MPa, it delivers 3927 N push and 3681 N pull.
The rear adjuster screw lets you shorten the effective travel from its 170 mm nominal stroke down to 70 mm, creating a 70-170 mm window. It functions as a mechanical stop for end-position tuning and does not lock the load without air pressure.
