Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 300mm 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 SAIJ160BX300-30S
The AirTAC SAIJ160X300-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers substantial thrust, pushing with 14074N and pulling with 9425N at 0.7 MPa. A standout feature is the 270-300 mm usable travel window, allowing you to dial back the 300 mm nominal stroke by up to 30 mm during commissioning. This cylinder includes a SUS304 stainless steel rod for corrosion resistance and a magnetic piston for position sensing.
Because the 300 mm stroke is unsupported at this bore size, an external guide is recommended to manage side loads. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and is not a lock; the variable air cushions at both ends handle deceleration. For load-holding without live air pressure, consider the related SAIL or BSAI series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30S Is Used
Machine Changeovers
Dial in the exact 270-300 mm end-stop during product size transitions without swapping the cylinder or adding external mechanical stops.
Sensor Positioning
Leverage the integrated magnet with DMSE electronic sensors to confirm travel endpoints within the fine-tuned adjustment window.
Heavy Assembly Presses
Utilize the 14074N push force for heavy-duty pressing tasks while relying on the built-in air cushions for smooth end-of-stroke deceleration.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-30S the Right Cylinder?
Choose this 160 mm bore when you need high force (14074N push at 0.7 MPa) combined with on-the-fly end-position tuning. If your application requires less force, stepping down to a 125 mm bore yields 8590N push, whereas moving up to a 200 mm bore provides 21991N. The adjustable stroke is ideal for machine changeovers where product sizes vary, eliminating the need to physically swap cylinders or add external stops.
This configuration uses PT tapered ports and a SUS304 stainless steel rod. The integrated magnet (-S) works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors in the dual-side sensor grooves. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders without claiming brand equivalence. Remember that neither the rear adjuster nor the cushions will hold a load without continuous air pressure.
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 SAIJ160BX300-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw lets you mechanically shorten the 300 mm nominal stroke by up to 30 mm, creating a 270-300 mm usable travel window. It functions as a hard stop for fine-tuning end positions and does not lock the load without live air pressure.
