About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-50S
The AirTAC SAIJ100X170-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 120 to 170 mm usable travel window, allowing you to dial back the nominal 170 mm stroke by up to 50 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks with precision.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a -S magnet for position sensing. The integrated sensor grooves on both sides of the extruded aluminum barrel accept CMSE reed or DMSE solid-state switches. It uses PT tapered ports and offers adjustable pneumatic cushioning at both ends to absorb impact energy.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-50S Is Used
Variable End-Stop Forming
Dial in the exact retraction point for a forming press during material thickness changeovers using the 50 mm rear adjustment window.
Product Diverting
Adjust the stroke length on a sorting diverter arm on the fly to accommodate different package sizes without changing the cylinder.
Machine Setup Calibration
Fine-tune the end position of a heavy-duty clamping fixture at commissioning, utilizing the 3927 N push force to secure the workpiece.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-50S the Right Cylinder?
Choose this 100 mm bore actuator when an application demands high thrust along with variable end-stop positioning. If you need less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The 50 mm adjustment window is ideal for product changeovers, letting you fine-tune the retract position without adding external stops or swapping the cylinder.
Because the nominal stroke is 170 mm, the 25 mm rod handles moderate side loads well, though any long unsupported load still requires an external guide. Remember that the rear adjuster acts purely as a mechanical stop and does not hold the load without live air; for true load-holding, consider an external rod lock, a SAIL pilot-lock cylinder, or a BSAI clamp-lock variant. To match this ISO 15552 footprint exactly, specify the 100 mm bore, 170 mm stroke, 50 mm adjust, PT ports, and the -S magnet.
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 SAIJ100 Adjustable Cylinder SAIJ100BX170-50S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective travel from the 170 mm nominal stroke down to 120 mm. This stop only sets the travel end and does not lock the load without live air pressure.
