About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-50
The AirTAC SAIJ160X65-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 65 mm travel back by up to 50 mm, creating a highly flexible 15-65 mm usable window. Built with an extruded aluminum barrel, it delivers robust thrust up to 14074 N at 0.7 MPa and operates at speeds of 30-500 mm/s.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster functions purely as a mechanical stop for end-position tuning during commissioning; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-50 Is Used
End-Stop Calibration
Dial in the exact retract position within the 15-65 mm window during machine commissioning without adding external stopper blocks.
Product Changeover
Quickly adapt the cylinder travel for different sized parts on a packaging line using the 50 mm rear adjustment range.
Heavy Assembly Press
Leverage the 14074 N push force at 0.7 MPa to seat heavy components, fine-tuning the final 15-65 mm stroke to prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX65-50 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires the 10053 N pull force at 0.5 MPa and the ability to dial in the exact end-stop on the fly without swapping components. If your setup only needs a fixed 65 mm stroke, the standard SAI series is simpler, but the SAIJ rear screw is invaluable for product changeovers. Because the stroke is under 300 mm, side-load risks are lower, yet the 40 mm rod diameter still handles substantial guide loads.
When replacing an ISO 15552 cylinder, match these exact parameters: 160 mm bore, 65 mm nominal stroke, 50 mm adjustment range, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options, and no magnet. Note that SAIJ omits FB, CA, CB, and CR mounts.
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 SAIJ160 Adjustable Cylinder SAIJ160BX65-50 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 65 mm nominal stroke by up to 50 mm. This yields an effective travel window of 15 to 65 mm. The adjuster only sets the travel end and does not lock or hold the load without live air pressure.
At 0.7 MPa operating pressure, the SAIJ160X65-50 provides a push force of 14074 N and a pull force of 9425 N. The maximum push force at 1.0 MPa is 2050 kgf.
