Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 950mm 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 SAUJ100X950-100
The AirTAC SAUJ100X950-100 is a double-acting single-rod profile cylinder with an on-site extend stroke adjustment window of 100mm. You can trim the usable extend stroke from 950mm down to 850mm using the external stop screw. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100mm bore delivers 3927N push and 3681N pull at 0.5MPa, peaking at 801kgf at 1.0MPa. For sizing, the safe working load is roughly 2356N (about 60% of the 0.5MPa push), yielding a 200kg vertical lift capacity with a 2:1 margin. Note this SKU lacks a magnet (-S) so it cannot take CMSG/DMSG/EMSG sensors. Operating temperature is -20 to +70C, with a Viton H seal option extending to 150C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100 Is Used
Long-Press Forming
Needs field stroke tuning to set precise 850-950mm mold closure distances on heavy press equipment without machinery redesign.
High-Bay Pusher
Requires adjustable extend stops to handle varying pallet depths at upper levels, using the 100mm window for exact ejection.
Large Part Diversion
Demands on-site stroke trimming to deflect heavy goods of differing widths safely across a wide transfer belt.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100 the Right Cylinder?
When sizing, compare both neighboring bores and forces: an 80mm bore gives 2513N push at 0.5MPa, while this 100mm bore provides 3927N. Choose the SAUJ over a fixed SAU when your machine build requires final end-position tuning without buying a new cylinder. The 100mm adjust window lets you cut the extend stroke by up to 100mm on-site. Mounting options include Basic, FA flange, and LB foot, compatible with the AirTAC SC series only. Because this is a 950mm stroke, you must use external guides to prevent rod bending and manage side loads. This non-magnetized SKU cannot accept sensors.
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 SAUJ100X950-100 FAQ
At 0.5MPa it provides 3927N push and 3681N pull, 5497N push at 0.7MPa, 7068N at 0.9MPa, and 801kgf max at 1.0MPa. The 950mm nominal extend stroke can be shortened by up to 100mm on-site via the external stop screw, yielding an 850-950mm usable range.
No. This SKU lacks a magnet so it cannot take CMSG/DMSG/EMSG sensors. A plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. For a held load use an external rod lock or pilot-operated check valve. The stop screw sets end position, not a load lock.
