About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-30
The AirTAC SAIJ160X950-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 920 to 950 mm. It delivers robust performance, generating 9425 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This unit is configured with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features PT tapered G3/4 ports. The 40 mm rod and M36x2 thread provide substantial rigidity, though at 950 mm of travel, an external guide is highly recommended to manage side loads. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-30 Is Used
Variable End-Stop Tuning
Dial in the exact 920 to 950 mm end-position during machine commissioning to accommodate varying product lengths without physically swapping the actuator.
Heavy-Duty Changeover
Quickly adjust the retract stop on production lines handling different material sizes, leveraging the 18095 N push force at 0.9 MPa for robust pressing.
Long-Stroke Assembly Press
Utilize the 950 mm travel for large-format component placement, relying on the rigid 40 mm rod and external guides to maintain precision over long extensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-30 the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (3681 N pull at 0.5 MPa) is insufficient for your heavy-duty application, or step down if a 125 mm bore (5734 N pull) provides enough force. The adjustable stroke is ideal for machine setup and product changeover, allowing you to dial in the exact end-stop without swapping cylinders or adding external stops. For load-holding without continuous air pressure, this cylinder is not a lock; you should select an AirTAC SAIL or BSAI model instead. It is dimensionally interchangeable with ISO 15552 mounting interfaces, using the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and PT G3/4 ports.

- ✓ 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 SAIJ160AX950-30 FAQ
At 0.5 MPa, the push force is 10053 N and the pull force is 9425 N. At 0.9 MPa, it delivers a push force of 18095 N and a pull force of 14074 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 920 to 950 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
