About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-30S
The AirTAC SAIJ40X130-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 130 mm stroke and a 30 mm adjustment range, it provides a usable travel window of 100-130 mm. This enables precise end-position tuning at commissioning without swapping the cylinder or adding external stops. Delivering 879 N of push force at 0.7 MPa, it is built to handle demanding industrial positioning tasks.
This model features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors mounted into the extruded aluminum barrel grooves. The rear adjuster acts purely as a mechanical stop to set deceleration and travel limits, meaning it will not hold a load without live air pressure. For load-holding without continuous pressure, an external rod lock or related types like SAIL or BSAI are required.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-30S Is Used
Machine Changeover
Dial in the 100-130 mm travel window during product size transitions without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Use the 30 mm rear adjuster to fine-tune the retract end-position at commissioning, compensating for mechanical tolerance stack-ups.
Corrosive Environments
Leverage the SUS304 stainless steel rod and standard TPU seals for reliable actuation in washdown or mildly corrosive industrial settings.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-30S the Right Cylinder?
Choose this 40 mm bore when your application requires the 879 N push force at 0.7 MPa, bridging the gap between the 32 mm bore (563 N) and the 50 mm bore (1374 N). The adjustable 100-130 mm travel window is ideal for machine setups requiring variable end-stops or frequent product-size changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot provide. Because the PT port thread and G1/4 air supply are standard, integrating this cylinder into existing ISO 15552 pneumatic layouts is straightforward.
When replacing an ISO 15552 cylinder, match the 40 mm bore, 130 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR configurations. Since the 16 mm rod and M12x1.25 thread carry reasonable side load capacity, always ensure proper guidance for optimal seal life.

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 SAIJ40BX130-30S FAQ
At 0.7 MPa operating pressure, this 40 mm bore cylinder provides 879 N of push force and 528 N of pull force. The maximum thrust is 128 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective stroke by up to 30 mm, giving a usable travel window of 100 to 130 mm. It sets the travel end but does not lock the load without live air pressure.
