About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75
The AirTAC SAIJ160X900-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 900 mm travel that can be fine-tuned down by up to 75 mm, yielding an effective 825-900 mm working window. Belonging to the 160 mm bore class, it delivers robust thrust up to 18095 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This variant incorporates an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Because the stroke extends to 900 mm, an external guide mechanism is highly recommended to prevent excessive side-loading on the piston rod.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75 Is Used
Heavy Machinery Setup
Dials in the exact 825-900 mm end position during heavy equipment commissioning without swapping actuators.
Product Changeover
Adjusts the stroke length on the fly to accommodate different sized pallets or products on a manufacturing line.
Large Assembly Presses
Provides the massive 18095 N thrust needed for pressing operations while allowing precise mechanical bottoming adjustment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-75 the Right Cylinder?
Select this 160 mm bore actuator when an application demands high thrust, such as 14074 N at 0.7 MPa, combined with variable end-stop positioning. If the 825-900 mm adjustment window exceeds your spatial constraints, stepping down to a 125 mm bore offers 8590 N at 0.7 MPa. Conversely, larger loads requiring up to 21991 N at 0.7 MPa necessitate the 200 mm bore size.
The rear adjuster screw allows precise end-position tuning during commissioning or product changeovers without adding external stops. Remember that this adjuster acts only as a travel stop and does not hold the load dynamically; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. This model uses the standard SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at speeds of 30-500 mm/s.

- ✓ 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 SAIJ160AX900-75 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 900 mm down to 825 mm. It sets the travel end but does not lock the load without live air pressure.
