About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-100
The AirTAC SAIJ160X800-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that provides a usable travel window of 700 to 800 mm. Delivering a robust 14074 N of push force at 0.7 MPa, this 160 mm bore actuator is engineered for heavy-duty positioning. Its extruded aluminum barrel incorporates sensor grooves on both sides for straightforward detection integration.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a PT tapered port thread. The rear adjustment screw acts purely as a mechanical stop to trim the retract end-position during commissioning or product changeovers, without requiring cylinder replacement or external stops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-100 Is Used
Long-Stroke Positioning
Dial in the exact 700-800 mm travel needed for large-format material handling without adding bulky external stopper blocks to the machine frame.
Machine Changeover
Quickly reconfigure the retract end-stop for different product sizes on a packaging line using the rear adjustment screw instead of swapping actuators.
Heavy-Duty End Tuning
Fine-tune the final resting position of heavy 14074 N loads at 0.7 MPa during initial commissioning to perfect timing and avoid mechanical crashes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-100 the Right Cylinder?
Choose this adjustable-stroke model when an application demands precise end-position tuning over swapping in a fixed-stroke SAI cylinder. If the 10053 N push force at 0.5 MPa is insufficient, stepping up to the 200 mm bore yields 15708 N; conversely, dropping to the 125 mm bore provides 6136 N. The SAIJ160X800-100 uses PT G3/4 ports and an M36x2 rod thread.
Because the nominal stroke is 800 mm, the 40 mm rod and M36x2 thread still require an external guide to prevent excessive side-loading on the seals. The rear adjuster and air cushions only decelerate the load; they do not hold position without live air. For true fail-safe load holding, select an SAIL pneumatic lock or BSAI clamp-lock cylinder. Mounting options are limited to 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 SAIJ160AX800-100 FAQ
The rear mechanical stopper allows you to shorten the effective travel from the nominal 800 mm down to 700 mm, creating a 100 mm adjustment window. It acts as a physical stop to set the retract position and is not a lock.
At 0.7 MPa operating pressure, the SAIJ160X800-100 provides 14074 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 18095 N.
