About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-30
The AirTAC SAIJ100X290-30 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the nominal 290 mm stroke by up to 30 mm. This creates a precise 260-290 mm usable travel window, ideal for fine-tuning end positions during commissioning or product changeovers without swapping out the hardware. It delivers substantial thrust, generating 5497 N of push force and 7068 N at 0.9 MPa.
Built with a standard carbon steel piston rod and M20x1.5 rod threading, this 100 mm bore unit handles robust loads while utilizing PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop and works alongside the adjustable air cushions at both ends to decelerate the load, but it does not lock the position without continuous air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-30 Is Used
Machine Setup Changeover
Dial in the exact 260-290 mm end-stop during product family changeovers, using the 30 mm rear adjustment to match new fixture lengths without disassembling the line.
Variable End Stops
Act as a configurable diverter or stop gate on a conveyor, allowing operators to fine-tune the retract position by up to 30 mm to accommodate varying package dimensions.
Assembly Press Positioning
Provide 5497 N of pressing force at 0.7 MPa with an adjustable stroke, enabling precise depth control for pressing bearings or pins without rigid custom spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-30 the Right Cylinder?
Choose this SAIJ100X290-30 when your application requires exact end-position tuning within a 260-290 mm window, avoiding the need to bolt on external stops or order custom-length cylinders. If your changeover requirements demand less travel, stepping down to an 80 mm bore yields 3518 N of push force at 0.7 MPa, whereas moving up to a 125 mm bore provides 8590 N for heavier loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR options.
Because the 290 mm stroke creates a long lever arm, an external guide is recommended to prevent side-loading damage to the rod and seals. For applications that must hold a load statically without live air pressure, note that this rear adjuster is a stop and not a lock; consider an AirTAC SAIL or BSAI series cylinder for true load-holding requirements.

- ✓ 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 SAIJ100X290-30 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides 5497 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 acts as an external stop, allowing you to shorten the effective stroke from the nominal 290 mm down to 260 mm. This provides a 30 mm tuning window for precise end-position setup without replacing the cylinder.
