Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30S 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 SAUJ100X900-30S
The AirTAC SAUJ100X900-30S is a double-acting single-rod profile cylinder with an external stop screw, letting you trim the extend stroke on-site by up to 30 mm. You get a usable extend range of 870-900 mm from the 900 mm maximum. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore delivers substantial power: 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. For payload sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of around 200 kg with a 2:1 safety margin. The -S suffix means a built-in magnet is present for CMSG, DMSG, or EMSG position sensing.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30S Is Used
Heavy Press Tonnage
Delivers up to 7068 N of extend force at 0.9 MPa for forming heavy sheet metal assemblies where the final 30 mm contact position requires on-site tuning.
Pallet Positioning Gate
Moves large 200 kg logistics pallets vertically, using the magnetic sensing to confirm gate closure and the stop screw to dial in the exact resting height.
Bulk Material Diverter
Actuates a heavy routing flap on a packaging line, allowing maintenance crews to shorten the extend stroke by up to 30 mm to accommodate new flap geometry.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30S the Right Cylinder?
When sizing this actuator, compare it against the 80 mm bore (2513 N push at 0.5 MPa) and verify your system can supply enough air for the 100 mm chamber. The 30 mm adjust window is ideal for finalizing machine setup without machining a custom external stop. Mounting options include Basic, FA flange, and LB foot styles, with compatibility matching the AirTAC SC series. Because the 900 mm stroke is long, always use external guides to prevent rod bending and manage side loads. For high-temperature environments up to 150 C, select the Viton H seal option instead of the standard -20 to 70 C range.
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 SAUJ100X900-30S 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, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The 900 mm nominal extend stroke can be shortened by up to 30 mm on-site using the external stop screw, yielding an 870-900 mm usable range. It uses a 1/2 inch port and 29 mm adjustable air cushions.
No, a plain cylinder does not hold a load on air loss; the piston will drift and the cushion only decelerates near the end of the stroke. The stop screw sets the end position but is not a load lock. For vertical holding, use an external rod lock or pilot-operated check valve. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG electronic switches.
