About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-50
The AirTAC SAIJ160X750-50 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It delivers a robust 18095N of push force at 0.9 MPa and features a 750mm nominal stroke. An integrated rear adjusting screw allows you to trim the effective travel back by up to 50mm, creating a 700-750mm usable window to perfectly dial in machine stops without external hardware.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and pairs with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Operating at speeds of 30-500mm/s, it relies on adjustable air cushions at both ends to decelerate massive loads smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-50 Is Used
Heavy Press Tuning
Dial in the exact 700-750mm end-of-stroke position during heavy press commissioning to accommodate material thickness variations without machining new stop blocks.
Pallet Changeover
Adjust the rear stopper by up to 50mm on the fly to handle different pallet lengths on a transfer line, ensuring precise indexing without cylinder removal.
Large Mold Handling
Securely move heavy molds into position using 18095N of thrust, relying on the adjustable end-stop to fine-tune the loading depth against the machine platen.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-50 the Right Cylinder?
Selecting this 160mm bore cylinder makes sense when your application demands extreme thrust—such as 14074N push at 0.7 MPa—that smaller bores cannot provide. The adjustable stroke is ideal for commissioning fine-tunes or product changeovers, allowing you to shift the end stop by up to 50mm rather than swapping out a fixed-stroke SAI cylinder. If your process requires holding a load in place without continuous live air pressure, note that this rear adjuster acts only as a travel stop, not a lock; you would need to explore an external pilot-operated check valve or the BSAI clamp-lock series instead.
Because this model features a 750mm stroke, the long unsupported rod extension requires an external guide to prevent excessive side-loading and premature seal wear. When matching ISO 15552 replacements, confirm the 160mm bore, 750mm stroke, 50mm adjustment, PT port thread, and the specific mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this SKU omits the -S magnet; adding it enables CMSE reed and DMSE electronic solid-state sensor integration.

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 SAIJ160AX750-50 FAQ
At 0.9 MPa operating pressure, this 160mm bore cylinder provides 18095N of push force and 9425N of pull force at 0.5 MPa. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 750mm nominal stroke by up to 50mm, providing a usable travel window of 700-750mm. It sets the end position but does not lock the load without live air pressure.
