About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-20
The AirTAC SAIJ160X375-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 355 to 375 mm, allowing you to trim the retract position by up to 20 mm during commissioning. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers 14074 N of push force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Because the nominal stroke is 375 mm, the 40 mm rod and M36x2 thread provide necessary rigidity, though an external guide is recommended to manage side loads over this long travel. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-20 Is Used
Heavy Press Tuning
Dial in the exact 355-375 mm end position during machine commissioning to accommodate material thickness variations without external stops.
Product Changeover
Quickly adjust the retract stop by up to 20 mm when switching between different pallet sizes on a high-thrust handling line.
Long-Stroke Forming
Leverage 14074 N of push force at 0.7 MPa for large-scale forming tasks, using the rear stop to fine-tune the mold closure depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-20 the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy thrust—such as 14074 N push at 0.7 MPa—that exceeds the 5497 N push capacity of a 100 mm bore model. The adjustable 355-375 mm window is ideal for product changeovers where exact end-of-stroke positioning varies slightly, eliminating the need to swap cylinders or add external stops. If your force requirements are lower, stepping down to a 125 mm bore provides 8590 N push at 0.7 MPa.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 375 mm stroke, 20 mm adjustment, PT port thread, and mounting style. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR. This model lacks a magnet; adding the -S option enables CMSE reed and DMSE electronic sensors. Operating speed is 30-500 mm/s.

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 SAIJ160BX375-20 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 355 to 375 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 13200 N of pull force. It can achieve a maximum push force of 18095 N at 0.9 MPa.
