Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-20S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-20S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 900mm 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 SAUJ100X900-20S
The AirTAC SAUJ100X900-20S is a double-acting single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the 900 mm maximum stroke by up to 20 mm, yielding a usable range of 880-900 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same 100 mm bore. It features a 1/2 inch air port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at both ends.
This bore delivers substantial thrust: 3927 N push and 3681 N pull at 0.5 MPa, reaching 7068 N push at 0.9 MPa. A practical computed insight is a safe working load of roughly 2356 N, or a 200 kg vertical lift with a 2:1 margin. The -S suffix means a built-in magnet for CMSG, DMSG, or EMSG sensors. For high-heat environments, Viton H seals extend the operating range to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-20S Is Used
Press Stroke Calibration
Demands field stroke tuning to set precise bottom-dead-center on varying material thicknesses, using the stop screw for exact 880-900 mm positioning.
Divertor Arm Positioning
Requires adjustable extend limits to accommodate different package sizes on the fly without changing out the entire actuator assembly.
Pallet Stopper Adjustment
Needs on-site stroke trimming to handle mixed pallet heights safely, relying on the 3927 N push force to halt heavy loads securely.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-20S the Right Cylinder?
When sizing this unit, compare both directions: the 100 mm bore yields 3927 N push at 0.5 MPa, while the smaller 80 mm bore gives 2513 N. Choose the SAUJ over a fixed SAU when you need final extend length tuning without buying a new cylinder. The 20 mm adjust window is ideal for fine-tuning machine stops. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series. Because the -S magnet is present, you can fit reed or electronic switches. At 900 mm stroke, add 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 SAUJ100X900-20S 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 900 mm extend stroke by up to 20 mm on-site, giving a usable range of 880-900 mm.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG sensors for position detection. Note that a plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. The stop screw sets end position but is not a load lock. For held loads, use an external rod lock or pilot-operated check valve.
