Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30 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 SAUJ100X900-30
The AirTAC SAUJ100X900-30 is a double-acting, single-rod profile cylinder with an external stop screw that lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable working span of 870-900 mm. It features a 100 mm bore, a 1/2" port, and M20x1.5 rod threads. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This bore delivers substantial force: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. A practical computed insight is a safe working load around 2356 N (60% of the 0.5 MPa push), or a vertical lift capacity of roughly 200 kg with a 2:1 safety margin. It runs at 30-800 mm/s with 29 mm adjustable air cushions, and a Viton H seal option extends operation to 150 C.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30 Is Used
Large Press Dwell Adjustment
Fine-tune the extend dwell position on a heavy press by up to 30 mm to accommodate different material thicknesses without changing the actuator.
Pallet Stop Positioning
Adjust the stopping point for varying pallet sizes on a conveyor line by trimming the extend stroke on-site using the external screw.
Heavy Load Pusher Setup
Set the exact push-off distance for heavy cartons in a dispatch zone, relying on the 200 kg vertical lift capacity and 30 mm trim window.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X900-30 the Right Cylinder?
When sizing this actuator, look at neighboring bores: an 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires minor on-site extend length tuning without buying a new cylinder. Mounting options include Basic, FA flange, and LB foot styles, compatible with the AirTAC SC series. Because this is a non-magnet SKU, it cannot accept CMSG or DMSG sensors. For the 900 mm stroke, external guides are strongly recommended 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 SAUJ100X900-30 FAQ
It provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N at 0.9 MPa. The theoretical max is 801 kgf at 1.0 MPa. The nominal 900 mm extend stroke can be shortened by up to 30 mm on-site via the stop screw, giving a usable range of 870-900 mm. It uses a 1/2" port.
The external stop screw mechanically limits the piston extension to set the end position. This stop is not a load lock. A plain cylinder drifts on air loss, and the 29 mm air cushion only decelerates near the end. For load holding, use an external rod lock or pilot-operated check valve. Also, this SKU lacks a magnet and cannot take sensors.
