About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-40
The AirTAC SAIJ100X160-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 120 to 160 mm usable travel window, allowing you to dial back the nominal 160 mm stroke by up to 40 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles heavy positioning tasks with precision.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a travel stop, so an external rod lock or pilot-operated check valve is required to hold loads without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-40 Is Used
Machine Changeover
Dial in the exact retract position within the 120-160 mm window when switching product sizes on a machining line.
Variable End Stops
Fine-tune the end of stroke during setup without machining new hard stops or changing the cylinder mount.
Heavy Fixture Positioning
Leverage 3927 N of push force at 0.5 MPa to move heavy jigs, using the rear screw to set the precise resting distance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-40 the Right Cylinder?
Select this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) lacks the thrust for your heavy fixtures, but a 125 mm bore is oversized. The 40 mm adjustment window is ideal for product changeovers, letting you fine-tune the retract end position without swapping the cylinder or bolting on external stops. Unlike a fixed SAI cylinder, this SAIJ model adapts to varying end-stop needs on the fly.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 160 mm stroke, 40 mm adjustment, PT G1/2 port, and mounting choice. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. Since the stroke is under 300 mm, side-load stress is minimal, but always guide long unsupported loads.
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 SAIJ100BX160-40 FAQ
At 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 stroke by up to 40 mm from the 160 mm nominal length. This creates a 120 to 160 mm usable travel window for fine-tuning end positions.
