About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-40S
The AirTAC SAIJ100X75-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 3927N of push force at 0.5 MPa and provides a usable travel window of 35 to 75 mm, allowing you to trim the 75 mm nominal stroke by up to 40 mm during machine setup.
This unit includes a SUS304 stainless steel rod for superior corrosion resistance and is equipped with a magnet for CMSE reed and DMSE electronic sensors. It uses PT tapered G1/2 ports and relies on adjustable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-40S Is Used
Product Changeovers
Dial in the exact end-stop from 35 to 75 mm during packaging format changes without swapping the physical cylinder.
Machine Commissioning
Fine-tune the retract position at startup to perfect pressing or clamping depth on the fly.
Variable End Stops
Adjust the travel window dynamically for multi-model assembly lines requiring different stroke endings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-40S the Right Cylinder?
Choose this 100mm bore actuator when your application requires substantial thrust—such as 5497N at 0.7 MPa—and on-the-fly end-position tuning without adding external stops. If your force requirements are lower, stepping down to an 80mm bore yields 2513N at 0.5 MPa. The adjustable stroke is ideal for product changeovers, but remember the rear adjuster is a travel stop, not a lock; for load-holding without live air, select an AirTAC SAIL or BSAI cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 100mm bore, 75mm stroke, 40mm adjustment, PT G1/2 ports, SUS304 (B) rod material, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX75-40S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force reaches 7068N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 75mm nominal stroke by up to 40mm, creating a 35 to 75mm usable travel window. It only sets the end position and does not hold the load without live air pressure.
