Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 800mm 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 SAIJ160BX800-30
The AirTAC SAIJ160X800-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 770-800 mm, allowing you to dial back the 800 mm nominal stroke by up to 30 mm during commissioning. Equipped with a robust 40 mm SUS304 stainless steel rod, it generates 10053 N of pull force at 0.5 MPa, making it ideal for heavy-duty positioning.
This model features PT tapered ports and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not enabled out of the box. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position; it does not lock or hold the load without continuous live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30 Is Used
Heavy-Duty Press Tuning
Fine-tune the 770-800 mm travel window during press setup to accommodate varying material thicknesses without replacing the entire actuator.
Product Changeover Stops
Adjust the retract end-position on the fly when switching packaging sizes on a high-thrust line, leveraging the 10053 N pull force to shift heavy loads.
Long-Stroke Positioning
Utilize the 800 mm stroke for large-scale material transfer, dialing back the travel by up to 30 mm to perfect the end-of-stroke dwell time.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-30 the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust—stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa, whereas this SAIJ160X800-30 provides 10053 N. The adjustable stroke is highly beneficial for machine setup and product changeovers, allowing variable end-stops without physically swapping the cylinder or adding external stops. It supports a speed range of 30-500 mm/s.
Because the stroke is 800 mm, the long unsupported rod is susceptible to side-loading; an external guide is strongly recommended to prevent premature seal wear. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR options. To match this replacement exactly, specify: 160 mm bore, 800 mm stroke, 30 mm adjustment, PT ports, SUS304 rod, and no magnet.

- ✓ 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 SAIJ160BX800-30 FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder generates 10053 N of pull force and 14074 N of push force at 0.7 MPa. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 800 mm nominal stroke by up to 30 mm, creating a 770-800 mm usable travel window. It only sets the end position and does not hold the load without live air pressure.
