About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-10S
The AirTAC SAIJ100X900-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 890-900mm usable travel window, letting you trim the retract end-position by up to 10mm during commissioning without adding external stops. It delivers a robust 3927N push force at 0.5MPa, making it suitable for heavy-duty positioning tasks.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, fitting directly into the dual-side extruded barrel grooves. The 25mm carbon steel rod and M20x1.5 thread handle high side loads, while the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-10S Is Used
Machine Setup & Changeover
Dial in the exact 890-900mm retract position during product size changes without swapping the cylinder or repositioning hard stops.
Heavy-Duty Positioning
Leverage the 3927N push force at 0.5MPa to move heavy pallets or tooling carriages, fine-tuning the end stop to match machine variance.
Variable End Stops
Use the 10mm adjustment window to compensate for mechanical wear or slight material thickness variations on long-stroke assembly lines.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X900-10S the Right Cylinder?
Select this 100mm bore when a 63mm bore (1559N push at 0.5MPa) is insufficient, but a 125mm bore (6136N) would be excessive. The adjustable-stroke design is chosen over a fixed SAI cylinder when you need precise end-stop tuning for product changeovers. For load-holding without live air, note that the rear adjuster is a travel stop, not a lock; you would need an SAIL or BSAI cylinder instead.
To replace an ISO 15552 cylinder, match the 100mm bore, 900mm stroke, 10mm adjustment, G3/8 PT ports, and the -S magnet option. Because the 900mm stroke is long and unsupported, an external guide is recommended to prevent rod 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 SAIJ100X900-10S FAQ
At 0.5MPa it provides 3927N push and 3681N pull force. It operates on filtered air at 0.15-1.0MPa with a speed range of 30-800mm/s, supported by adjustable air cushions at both ends.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 900mm down to 890mm. It fine-tunes the end position but does not lock or hold the load without continuous air pressure.
