Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 375mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30S
The AirTAC SAIJ160X375-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 345 to 375 mm usable travel window. Built with a SUS304 stainless steel rod and a PT tapered port, it delivers 14074 N of push force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides, fully supporting CMSE reed and DMSE electronic switches for precise position feedback.
This 160 mm bore model uses a robust 40 mm rod and M36x2 thread to handle high side loads, though the 375 mm stroke still requires an external guide to prevent rod bending. The rear adjuster acts purely as a mechanical stop to fine-tune end positions during commissioning without swapping cylinders, and it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30S Is Used
Press Setup Calibration
Dial in the exact 345-375 mm end-stop during press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Changeover Stops
Adjust the rear stopper on the fly when switching product sizes on a conveyor line, saving time on mechanical retooling.
Heavy Assembly Positioning
Leverage the 14074 N push force to shift heavy assemblies into place while fine-tuning the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-30S the Right Cylinder?
Select this adjustable-stroke model when an application requires exact end-position tuning during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.5 MPa; if you need higher thrust, a 200 mm bore provides 21991 N at 0.7 MPa. To replace an ISO 15552 cylinder, match the 160 mm bore, 375 mm stroke, -30 mm adjustment, PT port, and -S magnet.
Because the 375 mm stroke exceeds 300 mm, an external guide is strongly recommended to manage side loads and prevent rod deflection. For load-holding without continuous air pressure, this cylinder is insufficient; the rear stopper only decelerates travel, so you should specify a SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX375-30S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can operate at pressures up to 1.0 MPa, yielding a maximum push force of 18095 N.
The rear adjuster screw allows you to shorten the nominal 375 mm stroke by up to 30 mm, creating a usable travel window of 345 to 375 mm. This stopper only sets the end position and does not lock the load without live air pressure.
