About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-30S
The AirTAC SAIJ100X30-30-S is a double-acting ISO 15552 profile cylinder with a rear-mounted stroke adjuster. It provides a 0-30 mm usable travel window from its 30 mm nominal stroke, allowing you to dial in the exact end position during commissioning. The carbon steel piston rod and M20x1.5 rod thread provide a robust interface for high side-load tolerance.
Delivering 3927 N of push force at 0.5 MPa, this bore handles heavy positioning tasks. The extruded aluminum barrel features sensor grooves on both sides, and the included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-30S Is Used
Precision End-Stop Tuning
Dial in the exact 0-30 mm travel window during machine setup to perfect end positions without physically swapping cylinders or adding external stopper blocks.
Product Size Changeover
Quickly adapt a heavy-duty press or diverter to new product dimensions by turning the rear adjuster screw, saving downtime on the production line.
Heavy Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or tooling fixtures accurately into their final mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X30-30S the Right Cylinder?
Choose this 100 mm bore over a smaller 80 mm unit when you need more than the 2513 N push force at 0.5 MPa that the 80 mm provides. The rear adjustment screw is ideal for variable end-stops and product changeovers, preventing the need to swap cylinders or bolt on external stops. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 30 mm stroke, 30 mm adjustment, PT tapered port threads, and the -S magnet option.
Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air. For load-holding without continuous pressure, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. Even with a 25 mm rod, long unsupported strokes require an external guide to prevent rod bending.

- ✓ 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 SAIJ100X30-30S FAQ
The rear adjuster screw acts as an external mechanical stop, allowing you to trim the effective travel from 0 to 30 mm. This creates a 0-30 mm usable travel window from the 30 mm nominal stroke for fine-tuning end positions at commissioning.
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.
