About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-30
The AirTAC SAIJ100X135-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 105 to 135 mm, allowing you to dial back the nominal 135 mm stroke by up to 30 mm during commissioning. In the 100 mm bore class, it generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavier manipulation tasks.
This SKU is built with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G1/2) and operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the internal magnet, so external CMSE or DMSE switches cannot be used without a magnet-equipped variant.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-30 Is Used
Product Changeover
Dial in the 105-135 mm travel window during line changeovers to accommodate varying package sizes without repositioning the cylinder mount.
Press Fit Tuning
Fine-tune the exact end-stop position during commissioning to control the pressing depth of heavy assemblies using the 3927 N push force.
Heavy Material Handling
Leverage the robust 100 mm bore and SUS420J2 stainless rod to push heavy workpieces or pallets in washdown-adjacent industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-30 the Right Cylinder?
Select this 100 mm bore model when your application requires substantial thrust—up to 3927 N at 0.5 MPa—and on-the-fly end-position tuning without swapping out the entire cylinder. If your process demands less force, stepping down to an 80 mm bore drops the push force to 2513 N at 0.5 MPa, which might suffice for lighter loads. The integrated rear stopper allows precise 105-135 mm travel adjustments for product size changeovers, eliminating the need to bolt on external stops. However, remember that this adjuster is strictly a travel stop, not a lock; the SAIJ will not hold a load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 footprint, specify 100 mm bore, 135 mm stroke, 30 mm adjustment, PT G1/2 ports, SUS420J2 rod, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts.

- ✓ 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 SAIJ100AX135-30 FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 7068 N. The operational speed range for this bore size is 30-800 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the 135 mm nominal stroke by up to 30 mm, creating a usable travel window of 105 to 135 mm. This allows precise end-position tuning at commissioning without changing the cylinder, but it only stops the piston—it does not lock or hold the load without continuous air pressure.
