Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-75S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-75S 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 SAUJ100X950-75S
The AirTAC SAUJ100X950-75S is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 950 mm nominal travel by up to 75 mm, yielding a usable range of 875 to 950 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore. This 100 mm bore uses a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
Force output is substantial: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N push at 0.9 MPa. A practical computed insight is a safe working load around 2356 N, or a 200 kg vertical lift with a 2:1 margin. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. For high-heat environments beyond the standard -20 to +70 C range, Viton H seals extend operation to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-75S Is Used
Variable Depth Pressing
Allows operators to dial in the exact 875-950 mm extend position for pressing assemblies of varying heights without changing tooling.
Adjustable Transfer Pusher
Tunes the push stroke on a packaging line to accommodate different carton sizes, ensuring precise placement at the end stop.
Multi-Tier Pallet Dispenser
Provides the flexibility to shorten the extend stroke on-site when adjusting the dispenser for different pallet stack heights.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-75S 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 here. The 75 mm adjust window is ideal for finalizing machine setup without machining a custom spacer. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series only. Because the -S magnet is present, you can directly mount reed or electronic switches. At a 950 mm stroke, external guides are strongly recommended to prevent rod bending and manage side loads. Choose this adjustable model over a fixed SAU when exact end positions vary between fixtures.
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 SAUJ100X950-75S FAQ
This 100 mm bore cylinder delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The 950 mm nominal extend stroke can be shortened by up to 75 mm via an external stop screw, giving an 875-950 mm working range.
The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. Note that the stop screw only sets the end position; it is not a load lock. The cylinder will drift on air loss because the cushion only decelerates. Use an external rod lock or pilot-operated check valve for secure load holding.
