About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-75S
The AirTAC SAIJ160X800-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 725 to 800 mm, allowing you to dial back the 800 mm nominal stroke by up to 75 mm during commissioning. It delivers a robust 14074 N push force at 0.7 MPa and operates at speeds of 30-500 mm/s.
This unit integrates a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster functions strictly as a travel stop for end-position tuning, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 725-800 mm window during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Size Changeover
Quickly adjust the rear stopper on automated lines to handle different product dimensions, reducing setup time and eliminating the need for external mechanical stops.
Heavy Load Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy jigs or fixtures into their exact final position, relying on the adjuster to set the precise travel limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-75S the Right Cylinder?
Select this 160 mm bore cylinder when your application requires heavy thrust up to 14074 N at 0.7 MPa alongside variable end-stop positioning. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa. Choose this adjustable-stroke model over a fixed SAI cylinder when you need to fine-tune the retract position on product changeovers without adding external stops. For load-holding without live air pressure, use a SAIL or BSAI cylinder instead, as this adjuster is not a brake.
This SAIJ configuration uses PT tapered ports (G3/4) and a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). Because the stroke is 800 mm, the M36x2 rod and long unsupported travel require an external guide to prevent excessive side-loading and rod sag.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ160BX800-75S FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 725 to 800 mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
At a standard 0.7 MPa operating pressure, the SAIJ160X800-75-S provides a push force of 14074 N and a pull force of 9425 N. It can deliver up to 18095 N of push force at 0.9 MPa.
