About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX110-75
The AirTAC SAIJ40X110-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel. With a nominal 110 mm stroke and a 75 mm adjustment range, you can dial the usable movement back to anywhere within a 35-110 mm window. This bore size delivers 879 N of push force and 528 N of pull force at 0.7 MPa, making it well-suited for moderate-load positioning tasks.
This configuration features a SUS304 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting position detectors. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX110-75 Is Used
Machine Changeover
Dial in the exact end-position during product size changes without swapping cylinders or bolting on external stops.
Variable End-Stops
Set a precise travel distance within the 35-110 mm window for operations requiring multiple stroke lengths from a single actuator.
Corrosive Environments
The SUS304 stainless steel rod provides reliable actuation in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX110-75 the Right Cylinder?
Choose this 40 mm bore if your application requires 879 N of push force at 0.7 MPa; step down to a 32 mm bore if your force requirements are closer to 563 N, or move up to a 50 mm bore for 1374 N. The 75 mm adjustment range is ideal for machines that frequently process varying product sizes, allowing you to reposition the end-stop during changeovers rather than physically swapping the cylinder or adding external stops. For load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI series cylinder instead of relying on the adjuster. When integrating this cylinder, match the PT porting, basic or TC mounting, and 110 mm stroke to your existing ISO 15552 footprint.
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 SAIJ40 Adjustable Cylinder SAIJ40BX110-75 FAQ
It features a rear mechanical stopper that lets you shorten the 110 mm nominal stroke by up to 75 mm, providing an adjustable travel window of 35 to 110 mm. The adjuster sets the travel end but does not lock or hold the load without continuous air pressure.
At 0.7 MPa, the cylinder provides 879 N of push force and 528 N of pull force. At a maximum operating pressure of 1.0 MPa, it can deliver up to 1130 N of push force.
