About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-50S
The AirTAC SAIJ160X650-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down by up to 50 mm, creating a precise 600-650 mm usable window without external stops. It delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and 14074 N of push force at 0.7 MPa. Built for demanding environments, this unit uses a SUS420J2 stainless steel rod (code A) and includes a magnet for position sensing.
The rear adjustment mechanism acts strictly as a travel stop to set deceleration and end positions, not as a load-holding brake. For true position retention without live air pressure, you must integrate an external rod lock or utilize related AirTAC series like SAIL or BSAI. This 160 mm bore model uses PT tapered port threads and operates at speeds between 30-500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-50S Is Used
Variable End-Stop Positioning
Dial in the exact 600 to 650 mm retraction end-point during initial machine setup to accommodate varying workpiece lengths without physically swapping out the cylinder.
Heavy Product Changeover
Quickly adjust the travel limit by up to 50 mm on automated assembly lines when switching between different product sizes or profiles, minimizing downtime.
Long-Stroke Deceleration Tuning
Fine-tune the rear stopper on this 650 mm stroke actuator to optimize the end-of-stroke deceleration rate for massive moving payloads safely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-50S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy force combined with on-the-fly end-position tuning during machine commissioning or product changeovers. If you need slightly less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N of pull but demands a larger footprint. The SAIJ160X650-50-S is dimensionally interchangeable per ISO 15552 mounting-interface dimensions. To match this exact configuration, specify the 160 mm bore, 650 mm stroke, 50 mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet option.
Because the nominal stroke is 650 mm, the 40 mm diameter rod is highly susceptible to side-loading and bending under long unsupported travel. An external guide rail must be used to prevent premature seal wear and rod damage. The integrated magnet works seamlessly with AirTAC CMSE reed switches and DMSE solid-state electronic sensors for precise end-of-travel detection.

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 SAIJ160AX650-50S FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum 1.0 MPa pressure, it delivers up to 2050 kgf of thrust.
The rear adjuster screw allows you to shorten the 650 mm nominal stroke by up to 50 mm, providing a usable travel window of 600 to 650 mm. The adjuster functions as a mechanical stop for end-position tuning and does not hold the load without continuous air pressure.
