About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-40S
The AirTAC SAIJ160X70-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel within a 30-70 mm window. Delivering massive thrust, it provides 14074N push force at 0.7 MPa and up to 18095N at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides, and this specific SKU includes a SUS304 stainless steel rod and a magnet for position detection.
The integrated rear stopper screw lets you dial in the exact end position during commissioning without adding external stops. Because this is a heavy-duty 160 mm bore, the M36x2 rod thread and 40 mm cushion length handle significant impact loads, while the PT tapered port ensures a secure high-flow pneumatic connection. It operates at speeds between 30-500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-40S Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a high-tonnage press during setup, using the 40 mm adjustment window to compensate for tooling wear without replacing the cylinder.
Product Size Changeover
Adapt large-scale automated machinery to different product heights by dialing the stroke back from 70 mm to 30 mm, enabling rapid line changeovers.
Heavy-Duty Positioning
Move massive payloads with up to 18095N of push force at 0.9 MPa while relying on the robust SUS304 stainless steel rod to resist corrosion in harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-40S the Right Cylinder?
Choose this 160 mm bore when you need extreme force that smaller bores cannot provide, such as stepping up from a 125 mm bore that yields 11045N at 0.9 MPa. The adjustable stroke is ideal for product changeovers on heavy machinery, letting you shift the end-stop by up to 40 mm rather than physically swapping cylinders. For load-holding applications without live air pressure, note that the rear adjuster functions strictly as a travel stop and not a brake; you should instead specify an SAIL lock cylinder or an external rod lock.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 70 mm nominal stroke, 40 mm adjustment range, PT port thread, and the -S magnet requirement. This SAIJ variant supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors.

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 SAIJ160BX70-40S FAQ
At 0.5 MPa it provides 10053N of push force and 9425N of pull force. At the maximum operating pressure of 0.9 MPa, the push force reaches 18095N.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this model, you can shorten the 70 mm nominal stroke by up to 40 mm, giving an adjustable usable travel window of 30 to 70 mm.
