Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40S 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 SAUJ100X950-40S
The AirTAC SAUJ100X950-40S is a double-acting, single-rod profile cylinder with an external stop screw that lets you shorten the extend stroke on-site by up to 40 mm. This yields a usable working stroke of 910 to 950 mm. The 100 mm bore uses a 1/2 inch port and a 25 mm rod. Its extruded aluminum profile barrel is notably shorter than an ISO 15552 cylinder of the same bore.
This unit includes a piston magnet for CMSG, DMSG, or EMSG switches. It delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa. A practical computed insight: the safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. Standard seals handle -20 to +70 C, while a Viton H option extends this to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40S Is Used
Divert Gate Positioning
Tuning the extend stop by up to 40 mm on-site lets operators perfectly align a heavy divert gate without machining new hard stops.
Pallet Stopper Adjustment
Accommodates varying pallet sizes by trimming the working stroke from 950 mm down to 910 mm to set the exact stopping point.
Large Press Tonnage Setup
Provides the high force needed for a forming press while allowing precise bottom-dead-center position tuning during initial tool setup.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-40S the Right Cylinder?
When sizing this actuator, compare it against the neighboring 80 mm bore, which provides 2513 N push at 0.5 MPa. The 100 mm bore yields 3927 N push at 0.5 MPa, scaling to 7068 N at 0.9 MPa. Choose this SAUJ model over a fixed SAU when your assembly requires minor on-site stroke adjustments without buying a new cylinder. The -40 adjust window is ideal for fine-tuning the end position. It supports Basic, FA, and LB mountings. The -S suffix means a magnet is built-in for electronic or reed sensors. Because the stroke is 950 mm, you must use external guides to prevent rod bending and manage side loads.
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 SAUJ100X950-40S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force is 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw allows you to shorten the 950 mm extend stroke by up to 40 mm, giving a usable range of 910 to 950 mm.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG position switches. A plain cylinder does not hold load on air loss; the piston drifts and the air cushion only decelerates near stroke end. The stop screw sets end position but is not a load lock. For a held load, use an external rod lock or pilot-operated check valve.
