About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-30
The AirTAC SAIJ160X230-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel within a 200 to 230 mm window. Using a 160 mm bore, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa and reaching 18095 N at 0.9 MPa. This makes it well-suited for heavy-duty positioning tasks requiring precise end-stop calibration.
This variant features a SUS304 stainless steel piston rod for superior corrosion resistance and utilizes PT tapered port threads for a robust pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop for commissioning flexibility, not a load-holding lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-30 Is Used
Heavy Press Tuning
Dial in the exact 200-230 mm travel during machine commissioning to set precise pressing depths on heavy industrial assemblies without external stopper blocks.
Product Changeover
Quickly adjust the retract end-position on automated lines when switching between product sizes, using the 30 mm trim window to accommodate varying part lengths.
Material Handling Stops
Provide a robust, adjustable physical end-stop for heavy material positioning, leveraging the 18095 N push force at 0.9 MPa to move substantial loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-30 the Right Cylinder?
Choose this 160 mm bore adjustable-stroke cylinder when your application demands high force and variable end-position tuning without swapping out the entire actuator. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N at 0.7 MPa. The built-in rear screw stopper is ideal for product changeovers, letting you dial in the exact 200-230 mm stroke on the fly.
Because this is a double-acting cylinder, the rear adjuster and the variable air cushions only decelerate the travel end; they cannot hold the load without continuous live air pressure. For positive load-holding, consider the SAIL or BSAI series, or use an external rod lock. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552. It omits FB, CA, CB, and CR mounts. With a 230 mm stroke, the 40 mm rod and M36x2 thread handle high side loads, but an external guide is recommended for heavy lateral forces.

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 SAIJ160BX230-30 FAQ
At a 0.7 MPa operating pressure, the 160 mm bore provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 230 mm stroke by up to 30 mm, creating a usable travel window of 200 to 230 mm for fine-tuning end positions at commissioning.
