About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-50
The AirTAC SAIJ100X600-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 550 to 600 mm usable travel window, allowing you to dial back the stroke by up to 50 mm during commissioning without swapping the cylinder or adding external stops. Delivering a robust 3927 N of push force at 0.5 MPa, it handles heavy loads with precision.
This 100 mm bore unit features a carbon steel rod with an M20x1.5 thread, paired with PT tapered port threads and a G1/2 air connection. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic sensors if a magnet is added later. The rear adjuster acts purely as a travel stop for end-position tuning, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-50 Is Used
Product Size Changeovers
Quickly adapt a 600 mm stroke to varying product lengths on a packaging line by dialing the rear stopper back up to 50 mm, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the exact retract distance during machine commissioning to perfectly time heavy 3927 N press operations without adding external stops.
Variable End-Stop Assembly
Set precise retraction limits for heavy-duty automated assembly stations, leveraging the 550-600 mm travel window to accommodate multiple jigs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X600-50 the Right Cylinder?
Choose this adjustable model when a fixed-stroke SAI cylinder cannot accommodate product changeovers or fine-tuning on a 600 mm stroke. If your application requires less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa; stepping up to a 125 mm bore provides 6136 N. Because the stroke is 600 mm, the M20x1.5 rod will experience leverage forces under load, so an external guide is recommended to prevent side-load wear.
For ISO 15552 replacement matching, specify the 100 mm bore, 600 mm stroke, 50 mm adjustment range, PT port thread, and your required mounting style from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this series. If you need true load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder instead of relying on the rear stopper.
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 SAIJ100X600-50 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder 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 effective travel from 600 mm down to a minimum of 550 mm. It sets the end position but does not lock the load without live air pressure.
