About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-50
The AirTAC SAIJ100X900-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 50mm adjustment range, creating an 850-900mm usable travel window for fine-tuning the retract end position without adding external stops. Equipped with a 25mm carbon steel rod and M20x1.5 thread, it delivers 3927N of push force at 0.5MPa, making it suitable for heavy-duty positioning tasks.
This model uses a PT tapered G1/2 port and includes variable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel features sensor grooves on both sides for adding CMSE reed or DMSE electronic switches. The rear adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-50 Is Used
Product Changeover Diverter
Adjusts the retract stroke by up to 50mm to accommodate different package sizes on a conveyor line without changing cylinder hardware.
Machine Setup Calibration
Provides a 850-900mm travel window to perfectly dial in the end-stop position during initial machine commissioning.
Heavy-Duty Positioning
Leverages 3927N of push force at 0.5MPa to move heavy pallets while allowing fine-tuning of the final retract position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-50 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires 3927N of push force at 0.5MPa (or 5497N at 0.7MPa). If your process demands less force, stepping down to an 80mm bore yields 2513N at 0.5MPa, whereas a 125mm bore provides 6136N for heavier loads. The 50mm adjustment range is ideal for product changeovers, allowing you to dial in the exact end-stop during commissioning rather than swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100mm bore, 900mm stroke, 50mm adjustment, PT G1/2 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 900mm, the long unsupported rod is susceptible to side-loading; always use an external guide to prevent binding and premature seal wear.
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 SAIJ100X900-50 FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 50mm, providing a usable travel window of 850-900mm. This lets you fine-tune the end position at commissioning without swapping the cylinder.
At 0.5MPa, it provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
