About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX110-30S
The AirTAC SAIJ40X110-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 80 to 110 mm, allowing you to dial back the nominal 110 mm stroke by up to 30 mm during commissioning. Delivering 879 N of push force at 0.7 MPa, it bridges the gap between smaller 32 mm bores and heavier 50 mm units.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. It works seamlessly with AirTAC CMSE reed and DMSE electronic sensors fitted into the dual-side sensor grooves on the extruded aluminum barrel. It uses PT tapered ports and includes adjustable air cushions at both ends to manage end-of-stroke impacts.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX110-30S Is Used
Product Changeover
Quickly fine-tune the retract end-position by up to 30 mm when switching a packaging line to a different carton size, avoiding the need to physically swap cylinders.
End-Stop Calibration
Dial in the exact 80 to 110 mm travel window during machine commissioning to perfectly time a pressing or pushing operation without adding external mechanical stops.
Sensor-Ready Automation
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches for precise position feedback in automated assembly lines.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX110-30S the Right Cylinder?
Select this 40 mm bore when an application requires roughly 879 N of push force at 0.7 MPa, stepping up from the 563 N offered by a 32 mm bore without committing to the larger 1374 N of a 50 mm unit. The adjustable stroke is ideal for machines requiring variable end-stops or fine-tuning during product changeover, providing setup flexibility that a fixed-stroke SAI cylinder cannot match. The rear adjuster acts purely as a mechanical stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock, a pilot-operated check valve, or the SAIL and BSAI cylinder series.
When ordering, confirm the 40 mm bore, 110 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some other ISO 15552 lines.
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 SAIJ40BX110-30S FAQ
At a 0.7 MPa operating pressure, this 40 mm bore cylinder provides 879 N of push force and 724 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 128 kgf.
The external rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 110 mm down to a minimum of 80 mm. It is a travel stop, not a lock, and does not hold the load without continuous live air pressure.
