Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 275mm stroke, G1/2 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 SAIJ100 Adjustable Cylinder SAIJ100X275-10S
The AirTAC SAIJ100X275-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and provides a usable travel window of 265 to 275mm, letting you dial in the exact end position during commissioning. The integrated -S magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches housed in the dual-side sensor grooves.
Unlike a fixed-stroke SAI cylinder, this model uses an external rear stopper screw to trim the retract stroke by up to 10mm without swapping hardware. The adjuster acts purely as a travel stop and works alongside the variable air cushions at both ends to decelerate the load. It does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series. The extruded aluminum barrel design utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10S Is Used
End-Stop Calibration
Dial in the exact 265-275mm retract position during machine commissioning to perfect product handling without machining new hard stops.
Line Changeover
Quickly adjust the stroke by up to 10mm to accommodate slight variations in package sizes moving down a packaging conveyor.
Press Positioning
Fine-tune the end position of a 3927N pressing assembly, relying on the rear stop to set the depth accurately.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10S the Right Cylinder?
Choose this 100mm bore cylinder when your application requires 3927N of push force (5497N at 0.7 MPa) and precise end-position tuning. If your process demands less force, stepping down to an 80mm bore provides 2513N at 0.5 MPa. The 10mm adjustment range is perfect for fine-tuning machine setup or accommodating minor product size changes on a line without adding external physical stops.
Because the nominal stroke is 275mm, ensure adequate guidance for long unsupported loads to prevent side-load wear on the 25mm rod and M20x1.5 rod thread. To match this ISO 15552 footprint, verify the 100mm bore, 275mm stroke, 10mm adjustment, PT port threads, and -S magnet option. The standard carbon steel rod and TPU seals handle standard industrial air filtration to 40um and temperatures from -20 to +70 C.

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 SAIJ100 Adjustable Cylinder SAIJ100X275-10S FAQ
The rear adjuster screw acts as an external stop that lets you shorten the effective stroke by up to 10mm, giving a usable travel window of 265 to 275mm. It allows fine-tuning of the end position without swapping the cylinder.
At 0.5 MPa operating pressure, it provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
