About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-20
The AirTAC SAIJ100X600-20 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 7068N of push force at 0.9 MPa. Its 600 mm nominal stroke can be dialed back by up to 20 mm, creating a precise 580-600 mm usable travel window for end-position tuning during commissioning. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches if a magnet is added later.
This 100 mm bore unit uses a G1/2 port and a robust 25 mm carbon steel rod with an M20x1.5 thread, providing high side-load resistance for heavy-duty handling. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some standard ISO cylinders.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-20 Is Used
Variable End-Stop Tuning
Dial in the exact 580 to 600 mm retract distance during machine setup to accommodate varying material thicknesses without reprogramming the motion controller.
Rapid Product Changeover
Quickly adjust the stroke end-position on packaging lines when switching between different carton sizes, using the rear screw to fine-tune the travel window.
Heavy-Duty Material Handling
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or chassis components, relying on the 25 mm rod to withstand substantial side loads.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-20 the Right Cylinder?
Select this 100 mm bore when an 80 mm cylinder lacks thrust, as stepping up from the 80 mm bore (4523N push at 0.9 MPa) to this model yields 7068N at the same pressure. The adjustable stroke is chosen over a fixed SAI cylinder when you need to fine-tune the retract end-stop during product changeovers without adding external stops or swapping the barrel. For any application with a 600 mm stroke, you must use an external guide to prevent rod binding, as the rear adjuster is a travel stop and not a lock.
To match this ISO 15552 cylinder for a replacement, verify the 100 mm bore, 600 mm stroke, 20 mm adjustment range, PT tapered port threads, and the specific mounting accessory. Because no -S magnet is specified here, position sensing is not possible out of the box. Remember that the rear adjuster and air cushions only decelerate the load; they do not hold position without live air pressure, so consider an AirTAC SAIL or BSAI for load-holding needs.
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 SAIJ100X600-20 FAQ
At 0.5 MPa it provides 3927N push and 3681N pull. At 0.9 MPa the push force is 7068N. The maximum rated force is 801 kgf at 1.0 MPa.
The rear adjuster acts as a stopper that lets you shorten the effective travel by up to 20 mm, creating a 580-600 mm usable window. It allows fine-tuning of the end position at commissioning without swapping the cylinder.
