About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-75S
The AirTAC SAIJ80X110-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear-mounted stroke adjuster. It delivers 2513 N of push force at 0.5 MPa and features a PT tapered port thread with a carbon steel rod. By integrating an external stopper screw, this model allows you to dial back the nominal 110 mm travel, providing a usable adjustment window of 35 to 110 mm without swapping hardware.
This wide 75 mm trim range is perfect for machines that require frequent product-size changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster functions strictly as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-75S Is Used
Product Changeovers
Dial in the 35-110 mm stroke window during format changes on packaging lines, accommodating varying carton sizes without replacing the cylinder.
Machine Commissioning
Fine-tune the retract end-position during setup, using the rear stopper to perfect the alignment of clamps and tooling under the 2513 N thrust.
Variable End Stops
Establish precise, repeatable stopping points for machining or pressing operations where the target depth shifts between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-75S the Right Cylinder?
Select this 80 mm bore when an application demands high thrust but highly variable end positions. If you need less force, stepping down to a 63 mm bore yields 1559 N of push force at 0.5 MPa; stepping up to 100 mm provides 3927 N. Choose this adjustable-stroke SAIJ over a fixed SAI when you need on-the-fly commissioning tweaks rather than machining external stops. For load-holding without continuous air pressure, pair the cylinder with an external pilot-operated check valve or select the SAIL or BSAI locking variants instead.
Because the 110 mm stroke is relatively short, side-loading is less severe than in long-stroke applications, but the 25 mm rod diameter and M20x1.5 rod thread still provide robust resistance to minor deflection. This model uses the reduced SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552, operating at speeds of 30-800 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 SAIJ80 Adjustable Cylinder SAIJ80X110-75S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back from the 110 mm nominal stroke by up to 75 mm, creating a usable 35-110 mm window. It sets the travel end and deceleration point but does not lock or hold the load without live air.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
