About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-30S
The AirTAC SAIJ100X600-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel, creating a 570-600 mm usable window from the 600 mm nominal stroke. It delivers 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa. This variant includes a magnet for position sensing and uses a carbon steel rod with a PT tapered port thread.
The rear adjuster acts purely as a mechanical stop to fine-tune end positions during commissioning or product changeovers without adding external stops. It does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This model supports AirTAC CMSE reed and DMSE electronic sensors, utilizing the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-30S Is Used
Machine Setup Fine-Tuning
Dial in the exact 570 to 600 mm end position during initial commissioning without machining external stopper blocks.
Product Size Changeovers
Quickly adapt the stroke length on packaging lines when transitioning to different carton or product sizes.
Variable End-Stop Automation
Use the rear adjuster to set precise retraction limits on heavy-duty material handling equipment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-30S the Right Cylinder?
Choose this 100 mm bore when 50 mm (982 N at 0.5 MPa) is too weak but a 125 mm bore is oversized. The adjustable stroke is ideal for setups requiring exact end-position tuning without swapping cylinders. When replacing an ISO 15552 cylinder, match the 100 mm bore, 600 mm stroke, 30 mm adjuster, PT ports, and the -S magnet requirement. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because this cylinder features a 600 mm stroke, the 25 mm diameter rod and M20x1.5 thread provide substantial support, but long unsupported strokes still require an external guide to manage side loads and prevent binding.
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 SAIJ100X600-30S FAQ
At 0.5 MPa it 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 acts as a mechanical stop, allowing you to shorten the 600 mm nominal stroke by up to 30 mm, resulting in a 570 to 600 mm travel window. It sets the end position but does not lock the load without live air.
