About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-10
The AirTAC SAIJ80X35-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 2513N push force at 0.5 MPa and allows you to dial back the 35mm nominal stroke by up to 10mm, creating a 25-35mm usable travel window for precise end-position tuning.
This unit features a SUS420J2 stainless steel rod and PT tapered port threads. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-10 Is Used
Precision End-Stop Tuning
Dial in the exact 25-35mm travel window during machine commissioning to perfect the retract position without external shims.
Product Changeover
Quickly adjust the rear stopper by up to 10mm on packaging lines when switching to a slightly different product size.
High-Force Clamping
Delivers 2513N of push force at 0.5 MPa for securely holding heavier workpieces during machining operations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX35-10 the Right Cylinder?
Choose this 80mm bore when an application requires higher force than a 63mm cylinder (1559N at 0.5 MPa) but less than a 100mm bore (3927N). The 10mm rear adjustment screw is ideal for fine-tuning the retract end at commissioning without adding external stops or swapping a fixed-stroke SAI cylinder.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. For true load-holding without continuous air, select an AirTAC SAIL or BSAI cylinder. This SAIJ80X35-10 is dimensionally interchangeable per ISO 15552.

- ✓ Required force at your working pressure
- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80AX35-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 35mm nominal stroke by up to 10mm, providing a usable travel window of 25-35mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
