Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-30S
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100BX75-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 75mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-30S
It features a SUS304 stainless steel rod, a PT tapered port, and a built-in magnet for position sensing. By turning the rear screw, you can trim the effective travel back by up to 30 mm, creating a precise 45-75 mm usable stroke window without swapping hardware.
This 100 mm bore actuator uses adjustable air cushions at both ends to decelerate heavy loads smoothly. The rear stopper acts purely as a travel end-setter for product changeovers, not as a load lock; maintaining position requires continuous live air. It accepts AirTAC CMSE reed and DMSE electronic sensors along its dual-side barrel grooves.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-30S Is Used
Product Changeover
Dial in the 45-75 mm stroke window during format size changes on a packaging line, avoiding the need to physically swap cylinders for different carton depths.
Press Fit Tuning
Fine-tune the exact bottoming position of a 3927 N press operation at machine commissioning, compensating for mechanical tolerance stack-up without external shims.
Variable End Stops
Provide an adjustable mechanical stop for heavy clamping fixtures, allowing operators to alter the clamping depth on the fly via the rear adjuster screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-30S the Right Cylinder?
The SUS304 rod provides excellent corrosion resistance for wet environments, and the robust M20x1.5 rod thread handles high side loads well. For fixed end-of-stroke applications without the need for commissioning adjustments, a standard SAI cylinder is a simpler alternative.
If your machine requires positive load-holding without constant air pressure, the SAIJ adjuster will not suffice, and you should specify an SAIL locking cylinder or an external rod lock. To replace this unit with another ISO 15552 dimensionally interchangeable cylinder, match the 100 mm bore, 75 mm stroke, 30 mm adjustment range, G1/2 port, PT thread, and the -S magnet requirement. Mounting is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 styles.
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 SAIJ100BX75-30S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the 75 mm nominal stroke by up to 30 mm, creating a usable travel window of 45 to 75 mm. This stopper sets the end position but does not lock the load without live air pressure.
