About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-30
The AirTAC SAIJ100X75-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 45 to 75 mm usable travel window. Delivering 3927 N of push force and 3681 N of pull force at 0.5 MPa, it handles heavy loads with a 25 mm carbon steel rod and M20x1.5 rod thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This model shines during machine commissioning, allowing you to dial in the exact retract position by up to 30 mm without swapping hardware. The rear stopper works alongside the adjustable air cushions at both ends to decelerate the load, but it does not hold position without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-30 Is Used
Product Changeovers
Quickly adapt machinery for different package sizes by adjusting the retract end-stop up to 30 mm without changing the cylinder.
Commissioning Tuning
Fine-tune the final end position during initial setup to perfect timing and mechanical alignment without adding external stopper blocks.
Heavy Assembly Presses
Leverage 3927 N of thrust at 0.5 MPa for pressing and seating components, using the adjustable stroke to control insertion depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-30 the Right Cylinder?
Choose this 100 mm bore when 80 mm (2513 N push at 0.5 MPa) is insufficient, but step down to 80 mm if your application falls under 2500 N to save space and air consumption. The SAIJ100X75-30 is ideal when a fixed 75 mm stroke SAI cylinder lacks the flexibility needed for product changeovers, giving you a 30 mm trim range. It features a PT tapered G1/2 port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting interfaces. Because the stroke is under 300 mm, side-load concerns are minimal, though long unsupported loads still need an external guide.
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 SAIJ100X75-30 FAQ
At 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 30 mm, giving an effective travel range of 45 to 75 mm. It acts as a travel stop and does not lock the load without air pressure.
