Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 900mm stroke, 1/2" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10S
The AirTAC SAUJ100X900-10S is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 10mm. You can trim the usable extend stroke from 900mm down to 890mm via an external stop screw. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions.
This 100mm bore delivers substantial power: 3927N push and 3681N pull at 0.5MPa, reaching 7068N at 0.9MPa. For sizing, the safe working load is roughly 2356N, and it can vertically lift about 200kg with a 2:1 margin. The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG sensors. Note that the stop screw sets the end position but does not lock the load; use an external rod lock for holding.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10S Is Used
Press Fit Tuning
Final insertion depth of heavy bearings needs exact field calibration. The 10mm stop screw window dials in the perfect press fit without remounting hardware.
Pallet Stop Alignment
Long 900mm extend strokes push large pallets into test bays. Adjust the final 10mm to square the load against a fixed wall precisely.
Divert Gate Positioning
Heavy divert gates on high-capacity lines need minor timing tweaks. The external screw lets operators shift the gate endpoint by up to 10mm on-site.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10S the Right Cylinder?
When sizing, compare both neighboring bores: the 80mm bore provides 2513N push at 0.5MPa, while this 100mm bore yields 3927N. Choose the SAUJ over a fixed SAU when you need final position tweaking on the machine without buying a new cylinder. The 10mm adjust window is ideal for fine-tuning. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series. The -S magnet allows electronic position sensing. Because the stroke is 900mm, you must support side loads with external guides to prevent rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/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 — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10S FAQ
At 0.5MPa it pushes 3927N and pulls 3681N. Push force is 5497N at 0.7MPa and 7068N at 0.9MPa, with a theoretical max of 801kgf at 1.0MPa. The nominal 900mm extend stroke can be shortened by up to 10mm on-site using the external stop screw, giving a usable range of 890-900mm.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG sensors. The cylinder does not hold the load on air loss; the cushion only decelerates near the end, and the stop screw sets position without locking. For secure load holding, install an external rod lock or pilot-operated check valve.
