Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40 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 SAUJ100X950-40
The AirTAC SAUJ100X950-40 is a double-acting single-rod profile cylinder with an external stop screw that lets you shorten the extend stroke by up to 40mm on-site, yielding a usable range of 910-950mm. 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 class delivers 3927N push and 3681N pull at 0.5MPa, peaking at 801kgf. A practical computed insight: the safe working load is roughly 2356N, allowing a vertical lift of about 200kg with a 2:1 margin. Choose SAUJ over a fixed SAU plus external stop when you need integrated, compact stroke adjustment. It supports Basic, FA, and LB mountings, and operates at 30-800mm/s.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40 Is Used
Press Stroke Tuning
Finalizes material forming depth by trimming the extend stroke up to 40mm on-site, ensuring precise contact without re-engineering the press head.
Divertor Arm Positioning
Adjusts the divertor arm reach by 40mm to handle varying package widths on the fly, preventing jams and ensuring smooth lane transitions.
Pallet Stop Calibration
Fine-tunes the pallet stop location to accommodate different pallet footprints, allowing quick changeovers without replacing the cylinder.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40 the Right Cylinder?
Size both ways: the 80mm bore offers 2513N push at 0.5MPa, while the 100mm bore here provides 3927N. The 40mm adjust window is ideal for final machine timing without machining hard stops. Mount using Basic, FA flange, or LB foot brackets, with compatibility matching the AirTAC SC series. Since this is a non-magnetized SKU, it cannot take CMSG, DMSG, or EMSG sensors. For the 950mm stroke, use external guides to prevent rod bending and manage side loads. The stop screw sets end position only; it is not a load lock.
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 SAUJ100X950-40 FAQ
At 0.5MPa it provides 3927N push and 3681N pull, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a max of 801kgf at 1.0MPa. The nominal 950mm extend stroke can be shortened by up to 40mm via the external stop screw, giving a 910-950mm usable range.
The external stop screw mechanically limits the piston extension, letting you trim the end position on-site. This stop is not a load lock; without live air the piston drifts and the 29mm cushion only decelerates near the end. For load holding on air loss, use an external rod lock or pilot-operated check valve.
