About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-75S
The AirTAC SAIJ100X135-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 60-135 mm usable travel window, letting you trim up to 75 mm from the 135 mm nominal stroke during commissioning without adding external stops. In the 100 mm bore class, it delivers 3927 N of push force at 0.5 MPa and utilizes a PT tapered port.
This specific SKU is built with a SUS420J2 stainless steel rod (option A) for corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-75S Is Used
Machine Changeover
Dial in the 60-135 mm stroke window on the fly during product size changeovers without swapping out the entire cylinder.
Variable End Stops
Use the rear adjusting screw to fine-tune the retract end position precisely during machine setup and commissioning.
High-Force Positioning
Leverage the 3927 N push force at 0.5 MPa for heavy-duty clamping or pressing tasks that require exact end-position tuning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-75S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires high force (up to 7068 N at 0.9 MPa) alongside variable end-stop positioning. If your setup needs less thrust, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. Because the 135 mm stroke is under 300 mm, side-load stress is moderate, but the M20x1.5 rod thread still requires external guiding for heavy lateral loads. The rear adjuster acts purely as a travel stop and does not lock the load; for true position holding without live air, specify an external rod lock, SAIL, or BSAI clamp-lock cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100 mm bore, 135 mm nominal stroke, 75 mm adjustment range, PT G1/2 port, and the -S magnet option.
Quick checklist
- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100AX135-75S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 135 mm nominal length, creating a 60-135 mm usable travel window. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without live air pressure.
