About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX100-10
The AirTAC SAIJ40X100-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 100 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 90-100 mm usable travel window. In the 40 mm bore class, it delivers 628 N of push force and 528 N of pull force at 0.5 MPa.
This variant is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if position feedback is required later. It operates at speeds between 30 and 800 mm/s and relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX100-10 Is Used
Machine Changeover
Dial in the 90-100 mm travel window during product size changes to set new end positions rapidly without changing the cylinder.
End-Stop Calibration
Fine-tune the retract position at commissioning using the rear screw, eliminating the need to fabricate external mechanical stops.
Material Handling
Sort or push lighter items reliably with 628 N of thrust while adjusting the stroke to accommodate varying package dimensions.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX100-10 the Right Cylinder?
Select this 40 mm bore cylinder when an application requires exact end-position tuning during commissioning or product changeovers, avoiding the need to swap components or bolt on external stops. If your setup demands greater thrust, stepping up to the 63 mm bore yields 1559 N of push force at 0.5 MPa; conversely, dropping to a 32 mm bore reduces the footprint while providing 402 N. Remember that the rear adjuster functions strictly as a travel stop, not a locking device. The SAIJ40X100-10 cannot hold a load without continuous air pressure, so for fail-safe load holding, consider an external pilot-operated check valve or the AirTAC SAIL locking cylinder series.
To match this exact ISO 15552 interchangeable replacement, configure the 40 mm bore, 100 mm stroke, 10 mm adjustment range, PT port threads, SUS304 rod material, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). The 100 mm stroke is well within standard limits, but always ensure the load is properly guided to prevent excessive side-loading on the rod.

- ✓ 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 SAIJ40BX100-10 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 a maximum 0.9 MPa, the push force increases to 1130 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 10 mm. This creates a 90-100 mm usable travel window for fine-tuning the end position without replacing the cylinder.
