About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-10
The AirTAC SAIJ160X70-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It generates 10053N of pull force at 0.5 MPa and features a robust 40mm piston rod with an M36x2 thread. By integrating a rear stopper, this unit allows you to fine-tune the end position at commissioning without swapping out the entire cylinder.
With a nominal stroke of 70mm and a 10mm adjustment range, the usable travel window spans 60-70mm. This specific SKU utilizes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and pairs with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for straightforward integration of CMSE or DMSE sensors if position feedback is later required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-10 Is Used
Heavy Press Tuning
Dial in the exact 60-70mm end-stop during heavy press commissioning to accommodate material thickness variations without adding external shims.
Product Changeover
Quickly adjust the stroke window on a packaging line when switching to a different pallet size, leveraging the 10mm rear screw for rapid setup.
High-Force Clamping
Utilize the 10053N pull force to secure heavy steel components, using the rear stopper to prevent over-travel and ensure consistent clamp depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX70-10 the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application demands extreme force—such as the 10053N pull at 0.5 MPa—over a short distance. If your setup requires less thrust, stepping down to a 125mm bore yields 5734N of pull force, while maintaining the same ISO 15552 mounting footprint. The adjustable-stroke design is chosen over a fixed SAI model when you need precise end-position tuning during machine setup or product changeovers.
Because the stroke is 70mm, external side-load guides are less critical than on longer strokes, but the heavy 40mm rod still handles substantial lateral stress. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device; the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider an external pilot-operated check valve or the SAIL lock variant. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160AX70-10 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 70mm down to 60mm, creating a 60-70mm usable window. It sets the end position but does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, it provides 10053N of pull force and 14074N of push force. It operates at speeds between 30-500 mm/s and features a 40mm rod with an M36x2 thread.
