About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX150-100
The AirTAC SAIJ40X150-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that permits a usable travel window of 50 to 150 mm. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, it provides robust actuation for mid-range tasks. The standard extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The rear adjuster functions purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without live air pressure. For applications needing true load-holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX150-100 Is Used
Changeover Position Tuning
Dial in the exact retract end-stop from 50 to 150 mm during machine changeovers to accommodate varying product lengths without adding external stopper blocks.
Adjustable Diverter Arm
Set precise sorting positions on a conveyor line by trimming the stroke back up to 100 mm, allowing one actuator to route multiple package sizes.
Commissioning End-Stop Setup
Fine-tune the final resting position during initial machine commissioning, using the rear screw to perfect timing without replacing the entire cylinder.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX150-100 the Right Cylinder?
Choose this 40 mm bore when you need a wide 50-150 mm adjustable end-stop range on a single actuator to handle frequent product changeovers without swapping cylinders. If your setup requires less force, stepping down to a 32 mm bore yields 402 N of push force at 0.5 MPa. If higher thrust is needed, a 50 mm bore provides 982 N. Because this is a 150 mm stroke, side loads are moderate, but an external guide is recommended if heavy lateral forces are present.
To match this ISO 15552 replacement exactly, specify: 40 mm bore, 150 mm nominal stroke, 100 mm adjustment range, PT G1/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and no magnet. Note that SAIJ omits the FB, CA, CB, and CR mountings found on some other series.
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 SAIJ40BX150-100 FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 128 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from its 150 mm nominal stroke down to 50 mm. It only sets the end position and provides deceleration; it does not hold the load without continuous air pressure.
