Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-75S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 550mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-75S
The AirTAC SAIJ160X550-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It generates 18095N of push force at 0.9 MPa and features a durable SUS304 stainless steel rod. Because this is an adjustable-stroke variant, its 550 mm nominal travel can be precisely dialed back by up to 75 mm, creating a 475-550 mm usable positioning window. This allows exact end-position tuning at commissioning without swapping out the physical cylinder.
The barrel is an extruded aluminum profile with sensor grooves on both sides, and this -S variant includes a magnet for CMSE reed and DMSE electronic solid-state switches. It uses PT tapered ports sized at G3/4. The rear adjuster acts purely as a mechanical stop to set the retract end position, meaning it cannot hold a load dynamically without continuous live air pressure. For position holding without air, an external SAIL lock or BSAI clamp-lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-75S Is Used
Heavy Press Tuning
Dial in the exact 475-550 mm end-stop during heavy press commissioning to accommodate material thickness variations without machining new spacers.
Product Changeover
Adjust the retract position on the fly during packaging line size changeovers, utilizing the 75 mm trim range to handle different pallet widths.
Large Assembly Fixtures
Securely position large automotive components using the 18095N push force, relying on the SUS304 rod for corrosion resistance in demanding environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-75S the Right Cylinder?
Choose this 160 mm bore when you need the 18095N push force at 0.9 MPa, stepping up from a 125 mm bore that provides 11045N. The adjustable 475-550 mm window is ideal for machines processing variable product sizes, letting operators fine-tune the retract end-stop during changeovers rather than adding external stops or buying a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 160 mm bore, 550 mm stroke, 75 mm adjustment, G3/4 PT ports, and the -S magnet requirement.
Because the 550 mm stroke is substantial, the 40 mm diameter SUS304 rod will experience leverage forces under side loading. Even with the robust rod thread of M36x2, an external guide rail should be installed to support the load and prevent premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets.

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 SAIJ160BX550-75S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear mechanical stopper allows you to shorten the 550 mm nominal stroke by up to 75 mm, providing an effective travel window of 475-550 mm. This adjuster sets the end position but does not lock the load without live air pressure.
