Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-75
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-75 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 SAUJ100X900-75
The AirTAC SAUJ100X900-75 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment window of 75 mm. You can trim the usable extend stroke from the 900 mm maximum down to 825 mm using the external stop screw. 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.
In the 100 mm bore class, this cylinder delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, reaching 7068 N at 0.9 MPa. For practical sizing, the safe working load is roughly 2356 N, and it can handle a vertical lift of about 200 kg with a 2:1 safety margin. This SKU lacks a magnet, so it cannot accept magnetic switches. Choose the Viton H seal option to raise the operating temperature from 70 C up to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-75 Is Used
Heavy Press Tonnage
Demands field stroke tuning to accommodate varying material thicknesses during heavy pressing operations.
Large Pallet Diverting
Requires adjusting the extend end position on-site to handle different pallet widths without changing actuators.
Bulk Lift Positioning
Needs precise extend stroke trimming to set exact vertical lift heights for diverse bulk container sizes.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-75 the Right Cylinder?
When sizing this model, compare it against the neighboring 80 mm bore, which provides 2513 N push at 0.5 MPa, versus the 100 mm bore delivering 3927 N at the same pressure. Select the SAUJ over a fixed SAU cylinder when your machine assembly requires on-site extend stroke tuning within the 825-900 mm range without buying a new actuator. Mounting options include Basic, FA flange, and LB foot types, compatible with the AirTAC SC series. Because this is a non-magnetized SKU, it cannot support CMSG, DMSG, or EMSG sensors. For the long 900 mm stroke, 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 SAUJ100X900-75 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force, reaching 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 extend stroke by up to 75 mm, giving a usable range of 825-900 mm. It uses a 1/2 inch port and 29 mm adjustable cushions. The stop sets the end position and is not a load lock.
No, this SKU lacks a magnet and cannot accept magnetic switches. A plain cylinder does not hold the load on air loss or when the valve is centered; the piston drifts and the cushion only decelerates near the stroke end. For a held load, use an external rod lock or a pilot-operated check valve.
