About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-50
The AirTAC SAIJ160X275-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This yields a usable 225 to 275 mm end-position window, enabling precise fine-tuning during commissioning or product changeovers without swapping out the unit. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers a robust 10053 N pull force at 0.5 MPa.
Because the adjuster functions strictly as a mechanical stop to set the travel end, it does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic solid-state switches if a magnet is later specified. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-50 Is Used
Machine Setup Changeover
Dial in the exact 225-275 mm travel window during product size changeovers, using the rear stopper to fine-tune end positions without adding external physical stops.
Heavy Material Pressing
Leverage the 14074 N push force at 0.7 MPa for heavy-duty pressing and forming tasks, utilizing the SUS304 rod for durability in demanding industrial environments.
Variable End-Stop Forming
Adjust the retraction end-point on the fly for batch-specific forming depths, relying on the 50 mm adjustment range to accommodate multiple part geometries on one line.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-50 the Right Cylinder?
Choose this 160 mm bore when your application requires high thrust, specifically 10053 N of pull or 14074 N of push at 0.7 MPa. If your force requirements are lower, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, while moving up to a 200 mm bore provides 15080 N of pull. The adjustable stroke is ideal for variable end-stops on machines that process different product sizes, giving you a 50 mm setup flexibility that a fixed-stroke SAI cylinder cannot provide.
When integrating this ISO 15552 interchangeable cylinder, match the 160 mm bore, 275 mm stroke, 50 mm adjustment, PT port thread, and SUS304 rod material. For any stroke of 275 mm or longer, an external guide is highly recommended to manage side-load, as even the robust 40 mm rod and M36x2 thread cannot entirely compensate for unsupported leverage. If your process requires true fail-safe load holding without continuous air, pair this cylinder with a SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.

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 SAIJ160BX275-50 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 275 mm stroke by up to 50 mm, creating a usable travel window of 225 to 275 mm. It sets the travel end and relies on the built-in air cushion for deceleration, but it does not lock or hold the load without live air pressure.
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At 0.7 MPa, the push force increases to 14074 N, with a maximum thrust of 2050 kgf at 1.0 MPa.
