About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX105-10
The AirTAC SAIJ40X105-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 95-105 mm usable travel window, allowing you to trim the 105 mm nominal stroke by up to 10 mm during commissioning without adding external stops. Delivering 628 N of push force at 0.5 MPa, it handles moderate actuation tasks with precision.
This variant is equipped with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU does not include a magnet for CMSE or DMSE electronic switches. Mounting options are restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX105-10 Is Used
Machine Setup Calibration
Dial in the exact 95-105 mm retract position during initial machine commissioning to achieve perfect end-stop alignment without machining new spacers.
Product Size Changeover
Quickly adjust the stroke end by a few millimeters when switching the production line to a slightly different package or component size.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for light assembly tasks in environments where moisture or mild chemicals would degrade standard carbon steel rods.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX105-10 the Right Cylinder?
Choose this 40 mm bore when a 32 mm bore (providing 402 N push force at 0.5 MPa) is insufficient, but a 50 mm bore (982 N) would be excessive. The 10 mm adjustable end-stop is ideal for product changeovers on a line, letting you fine-tune the retract position on the fly instead of swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider an external rod lock or the SAIL series.
For an exact ISO 15552 replacement, match the 40 mm bore, 105 mm stroke, 10 mm adjustment range, PT port thread, and your required mounting hardware. Because the stroke is 105 mm, side-load is minimal, but always ensure the load is guided to prevent binding.
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 SAIJ40BX105-10 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 128 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from the nominal 105 mm down to a minimum of 95 mm. It only sets the travel end and does not lock the load without continuous air pressure.
