Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10 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 SAUJ100X900-10
The AirTAC SAUJ100X900-10 is a double-acting single-rod profile cylinder with a 900 mm maximum stroke. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, yielding a usable range of 890-900 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 port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This 100 mm bore delivers substantial power: 3927 N push and 3681 N pull at 0.5 MPa, reaching 7068 N at 0.9 MPa. A practical computed insight for sizing is a safe working load around 2356 N, which equates to a vertical lift capacity of roughly 200 kg with a 2:1 safety margin. Standard TPU seals support -20 to +70 C, while a Viton H option extends heat resistance to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10 Is Used
Large Press Dwell Tuning
Trim the final 10 mm of extend stroke on-site to perfectly set the dwell position on a large forming press without machining hard stops.
Heavy Pallet Positioning
Shift heavy 200 kg loads vertically and fine-tune the exact lower stopping point to match varying pallet heights on the fly.
Bulk Material Diversion
Actuate a heavy diverter gate and adjust the extend end-point by a few millimeters to account for mechanical wear over time.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-10 the Right Cylinder?
When sizing, compare both neighbors: the 80 mm bore yields 2513 N push at 0.5 MPa, whereas this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed SAU when your assembly needs minor 0-10 mm end-position tuning without adding external stops. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because this is a non-magnet SKU, it cannot accept CMSG or DMSG sensors. Finally, at a 900 mm stroke, you must 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 SAUJ100X900-10 FAQ
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 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 nominal 900 mm extend stroke is the maximum; the external stop screw lets you shorten it by up to 10 mm on-site, giving a usable 890-900 mm range.
No. A plain cylinder drifts on air loss or when the valve is centered; the 29 mm air cushions only decelerate the piston near stroke ends, and the stop screw sets position but is not a load lock. For vertical load holding, install an external rod lock or a pilot-operated check valve.
