About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX10-10
The AirTAC SAIJ40X10-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a 0-10 mm usable travel window from its 10 mm nominal stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa, utilizing a G1/4 port. The integrated rear stopper screw allows you to fine-tune the end position at commissioning without adding external physical stops.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Unlike a fixed-stroke SAI cylinder, this adjustable version lets you dial in the exact retract distance on the fly, though the adjuster acts only as a travel stop and will not hold the load without live air pressure.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX10-10 Is Used
Machine Changeover
Dial in the exact 0-10 mm retract stop during product size changes without physically replacing the cylinder or adding external shims.
Short-Stroke Clamping
Provides 628N of precise clamping force where a fixed 10 mm stroke needs micro-adjustments to accommodate material thickness variations.
End-Position Tuning
Ideal for commissioning phases where the exact final position of a 10 mm stroke must be fine-tuned on the machine rather than engineered offline.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX10-10 the Right Cylinder?
Choose this 40 mm bore when you need 628N push force at 0.5 MPa, which sits neatly between the 402N of a 32 mm bore and the 982N of a 50 mm bore. An adjustable stroke is highly beneficial for short-travel setups requiring precise end-position tuning during machine changeover, eliminating the need to swap cylinders for minor length differences. If your application requires the load to stay in place without continuous air pressure, note that this rear adjuster is a stop rather than a lock; you would need an external rod lock or an AirTAC SAIL cylinder for true load holding. This model uses a PT tapered port thread and supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ40BX10-10 FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 10 mm. Since the nominal stroke is 10 mm, this gives you a usable travel window of 0-10 mm. The adjuster acts as a physical stop to set the retract end position precisely during commissioning.
At a standard 0.5 MPa operating pressure, the SAIJ40X10-10 provides 628N of push force and 528N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 879N.
