About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-40
The AirTAC SAIJ160X375-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. An external rear stopper allows you to trim the effective travel back by up to 40 mm, creating a usable stroke window of 335-375 mm without swapping the barrel or adding external stops. Delivering 18095 N of push force at 0.9 MPa, it handles substantial loads with a 40 mm SUS304 stainless steel rod and PT tapered ports.
The rear adjuster acts purely as a mechanical travel stop to dial in the exact retract position during commissioning or product changeover. It is not a locking device and will not hold a load without live air pressure. For position-holding without continuous air, consider the SAIL or BSAI series, or an external rod lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-40 Is Used
Variable End-Stop Tuning
Dial in the exact 335-375 mm retract position during machine setup to accommodate varying material thicknesses without physically remounting the actuator.
Product Changeover
Quickly adjust the stroke by up to 40 mm on a packaging line when switching between different product sizes, minimizing downtime and avoiding external stop hardware.
Heavy-Duty Positioning
Leverage the 18095 N push force at 0.9 MPa to push heavy pallets or molds into a precise end position, using the rear screw for final alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-40 the Right Cylinder?
Select this 160 mm bore cylinder when your application demands high thrust, such as 14074 N at 0.7 MPa, but requires a 335-375 mm stroke window to accommodate varying product sizes on a single line. The 40 mm SUS304 stainless steel rod provides excellent corrosion resistance and side-load capacity, though at 375 mm of travel, an external guide is recommended to prevent rod binding. The PT port thread and standard ISO 15552 mounting interface ensure straightforward integration.
If your force requirements are lower, stepping down to a 125 mm bore yields 11045 N of push at 0.9 MPa. Unlike a fixed-stroke SAI cylinder, this SAIJ model allows you to fine-tune the retract end-stop on the fly. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX375-40 FAQ
The rear adjuster acts as a mechanical stop that shortens the effective stroke by up to 40 mm, giving you a usable travel window of 335-375 mm. It sets the retract end position but does not lock or hold the load without continuous air pressure.
At 0.9 MPa operating pressure, the SAIJ160X375-40 generates a push force of 18095 N and a pull force of 9425 N. It operates at speeds between 30-500 mm/s.
