Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-40S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-40S 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 SAUJ100X900-40S
The AirTAC SAUJ100X900-40S is a double-acting single-rod profile cylinder with an on-site extend stroke trim of up to 40mm via an external stop screw. Your usable extend range is 860-900mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same 100mm bore. It features a 1/2 inch port and a built-in magnet for CMSG, DMSG, or EMSG sensors.
This 100mm bore delivers substantial power: 3927N push and 3681N pull at 0.5MPa, peaking at 801kgf at 1.0MPa. For sizing, the safe working load is roughly 2356N, and it can vertically lift about 200kg with a 2:1 safety margin. It runs at 30-800mm/s with 29mm adjustable air cushions. A Viton H seal option raises the operating temperature from 70C up to 150C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-40S Is Used
Press Fit Tuning
Allows operators to fine-tune the 40mm extend window on-site for precise press-fit depths without reprogramming motion controllers.
Variable Length Diverter
Adjusts the extend stop position mechanically to accommodate different package sizes on a high-thrust sorting line.
Pallet Positioning Stop
Provides a robust physical end-stop for heavy pallets, letting maintenance trim the 900mm stroke by up to 40mm as needed.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-40S the Right Cylinder?
When sizing, step down to an 80mm bore for 2513N push at 0.5MPa, or step up if you exceed this 100mm bore's 3927N capacity. Choose the SAUJ over a fixed SAU when you need final end-position tuning without buying a new cylinder. The 40mm adjust window lets you dial in the exact extend stop mechanically. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series. The -S suffix means a magnet is included for electronic position sensing. Because the 900mm stroke is long, always 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 SAUJ100X900-40S FAQ
This 100mm bore cylinder provides 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, and 7068N push at 0.9MPa, with a max of 801kgf at 1.0MPa. The nominal 900mm extend stroke can be shortened by up to 40mm on-site using the external stop screw, giving a usable range of 860-900mm. It uses a 1/2 inch port.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG switches. Regarding load holding, the stop screw only sets the end position and the air cushion only decelerates; neither acts as a load lock. The cylinder will drift on air loss or when the valve is centered. Use an external rod lock or pilot-operated check valve to hold a load securely.
