About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-75S
The AirTAC SAIJ160X290-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel from 290 mm down to 215 mm. This 75 mm adjustment window enables precise end-position tuning at commissioning without swapping the cylinder or adding external stops. It delivers a robust 9425 N pull force at 0.5 MPa, making it suited for heavy-duty positioning tasks.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a -S magnet for position sensing using AirTAC CMSE reed or DMSE electronic switches. It uses PT tapered ports sized G3/4, incorporates dual 50 mm air cushions for smooth deceleration, and operates at speeds of 30-500 mm/s. The extruded aluminum barrel provides standard ISO 15552 mounting dimensions.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-75S Is Used
Variable End-Stop Tuning
Dial in the exact 215-290 mm travel window during machine commissioning to perfect end-positioning without physically swapping out the cylinder.
Product-Size Changeovers
Quickly adapt automated lines to accommodate different product lengths by adjusting the retract stroke up to 75 mm via the rear stopper screw.
Heavy-Duty Positioning
Leverage the 9425 N pull force at 0.5 MPa to move heavy jigs or assemblies, using the 50 mm air cushions to smoothly decelerate the load at travel ends.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-75S the Right Cylinder?
Choose this 160 mm bore when you need high thrust that exceeds the 6136 N pull of a 125 mm cylinder, but do not require the massive 15080 N pull of a 200 mm bore. The adjustable stroke is ideal for product-size changeovers on a line, letting you dial in the exact 215-290 mm travel window during setup. Because the stroke is 290 mm, ensure an external guide supports the load to prevent excessive side-loading on the 40 mm rod and M36x2 thread.
The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not hold the load without live air pressure. For true fail-safe load holding, select an AirTAC SAIL or BSAI cylinder. This SAIJ model supports the reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the 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 SAIJ160BX290-75S FAQ
The nominal stroke is 290 mm, and the -75 adjustment code means you can shorten the effective travel by up to 75 mm. This provides an adjustable usable travel window of 215 to 290 mm via the rear stopper screw.
At 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
