About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-10
The AirTAC SAIJ160X375-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers robust thrust, generating 14074N of push force at 0.7 MPa and 9425N of pull force. The built-in rear stopper allows you to fine-tune the effective travel down to 365 mm from the 375 mm nominal stroke, providing a 365-375 mm usable window for precise end-position calibration during commissioning.
This heavy-duty actuator utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered G3/4 port threads. Because the 375 mm stroke is lengthy, the 40 mm rod diameter requires an external guide to prevent excessive side-loading. The rear adjuster acts solely as a travel stop to set deceleration endpoints and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-10 Is Used
Heavy Press Tuning
Dial in the exact end-stop position for large pressing operations, allowing up to 10 mm of adjustment to accommodate material thickness variations without changing tooling.
Product Changeover
Quickly reconfigure end-of-stroke positions on automated lines handling different product sizes, using the rear adjuster to fine-tune travel within the 365-375 mm window.
Large Assembly Calibration
Set precise retraction points for heavy assembly stations during initial commissioning, ensuring components mate perfectly under the 14074N push force available at 0.7 MPa.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-10 the Right Cylinder?
Choose this 160 mm bore model when an application demands high thrust that smaller bores cannot provide, such as stepping up from a 100 mm bore that yields 5497N push at 0.7 MPa. The 10 mm adjustable stroke is ideal for variable end-stops during machine setup or product changeover, avoiding the need to physically swap cylinders or bolt on external mechanical stops. For load-holding without continuous air pressure, note that the rear adjuster is not a lock; you should explore an AirTAC SAIL or BSAI clamp-lock cylinder instead.
When matching this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 160 mm bore, 375 mm stroke, 10 mm adjustment range, PT G3/4 ports, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Ensure external guiding is in place to support the long stroke.

- ✓ 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 SAIJ160BX375-10 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 375 mm nominal stroke by up to 10 mm. This creates a 365-375 mm usable travel window for fine-tuning the end position without swapping the cylinder.
