Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-10
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-10 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 SAUJ100X950-10
The AirTAC SAUJ100X950-10 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you trim the working stroke by up to 10 mm, yielding a usable range of 940-950 mm. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel is purposefully shorter than an ISO 15552 cylinder of the same 100 mm bore.
This bore delivers substantial force: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. For design sizing, the safe working load is approximately 2356 N (60 percent of the 0.5 MPa push figure), translating to a vertical lift capacity of about 200 kg with a 2:1 safety margin. The cylinder operates at 30-800 mm/s, and a high-temperature Viton H seal option extends the standard -20 to +70 C range up to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-10 Is Used
Heavy Material Diverting
Tuning the exact push-off distance of heavy pallets on a transfer line by up to 10 mm to compensate for varying package widths without reworking fixed hard stops.
Large Press Feeding
Feeding thick sheet metal into a large press where the final extend position needs minute 0-10 mm adjustments on-site to align the blank perfectly against the machine stops.
Automated Stacking
Pushing heavy containers onto stacking rollers, using the 3927 N force at 0.5 MPa and adjusting the extend end point slightly to accommodate different container lip heights.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-10 the Right Cylinder?
When sizing this 100 mm bore, compare it against the 80 mm option (2513 N push at 0.5 MPa) if your load is lighter, or step up if you need more than the 801 kgf maximum theoretical force at 1.0 MPa. Choose this SAUJ model over a fixed-stroke SAU when your assembly requires minor 0-10 mm end-position tuning without machining external hard stops. It supports Basic, FA flange, and LB foot mounts, and shares mounting compatibility with the AirTAC SC series. Because this SKU lacks the -S suffix, it has no magnet and cannot accept CMSG or DMSG sensors. Finally, at a 950 mm stroke, the 25 mm rod is highly susceptible to bending; always use external guide rails to support side loads and prevent rod damage.
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 SAUJ100X950-10 FAQ
This 100 mm bore cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. It uses a 1/2 inch port with an M20x1.5 rod thread. The nominal 950 mm extend stroke can be shortened by up to 10 mm on-site via an external stop screw, giving a 940-950 mm usable range.
No, this SKU lacks the -S magnet option, so it cannot accept magnetic sensors like CMSG or DMSG. Additionally, a plain cylinder does not hold load on air loss; the piston drifts and the 29 mm adjustable cushion only decelerates near the end of travel. The stop screw sets the end position but is not a brake. For a held vertical load, you must use an external rod lock or a pilot-operated check valve.
