About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-30
The AirTAC SAIJ160X800-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering 14074N of push force at 0.7 MPa. It features a precision rear stroke adjuster that creates a 770 to 800 mm usable travel window, allowing exact end-position tuning without swapping components. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE electronic switches.
Equipped with a 40 mm SUS420J2 stainless steel rod and M36x2 thread, this model handles substantial mechanical stress. The rear stopper functions strictly as a travel delimiter for commissioning and product changeover, not as a load lock. For applications requiring dead-stop positioning without live air pressure, an external pilot-operated check valve or the SAIL lock series is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-30 Is Used
Press Tonnage Calibration
Fine-tune the 770-800mm stroke end-position during press commissioning to perfectly set material forming depth without machining external stopper blocks.
Pallet Positioning Stops
Adjust the retract stop on the fly to accommodate different pallet lengths on a heavy-duty transfer line, ensuring precise indexing.
Heavy Weldment Clamping
Secure large steel fabrications for robotic welding, using the 40mm stainless steel rod to withstand harsh industrial splatter and high clamping forces.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-30 the Right Cylinder?
Select this 160 mm bore when 10053N at 0.5 MPa is insufficient and you need the next force tier. The 30 mm adjustment range is ideal for dialing in long-stroke machinery during setup, preventing the need for custom spacers. It uses a PT tapered G3/4 port and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Because the 800 mm stroke is substantial, the heavy piston assembly generates significant kinetic energy. While the 50 mm variable air cushions at both ends absorb impact, an external guide is strongly recommended to manage side loads and prevent rod deflection over this long unsupported travel distance.
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 SAIJ160AX800-30 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074N of push force and 13255N of pull force. It can deliver a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that trims the effective stroke back by up to 30 mm, creating a 770 to 800 mm travel window. It allows precise end-position tuning at commissioning but does not lock the load without continuous air pressure.
