Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-50
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-50 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 800mm 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 SAUJ100X800-50
The AirTAC SAUJ100X800-50 is a double-acting, single-rod profile cylinder with an 800 mm maximum stroke. An external stop screw lets you trim the extend stroke on-site by up to 50 mm, yielding a usable working stroke of 750-800 mm. 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 801 kgf at 1.0 MPa. For sizing, the safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa push force), and it can manage a vertical lift of approximately 200 kg with a 2:1 safety margin. Note this SKU lacks a magnet (-S), so it cannot accept CMSG or DMSG sensors. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-50 Is Used
Large Press Dwell Adjustment
Allows operators to fine-tune the 50 mm extend stop on-site to accommodate varying material thicknesses during heavy pressing operations.
Pallet Positioning Gate
Provides a robust 3927 N push force to divert heavy pallets, with the external screw letting you tweak the reach without changing hardware.
Heavy Load Rejecter
Handles large product rejection on a packaging line, using the adjustable end-position stop to dial in the exact ejection distance.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-50 the Right Cylinder?
When sizing this actuator, look at both neighboring bores and the 0.5 MPa forces. An 80 mm bore gives 2513 N push, while this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires on-site stroke tuning within that 50 mm window. Mounting options include Basic, FA flange, and LB foot styles, with physical mounting compatibility limited to the AirTAC SC series. Because this is an 800 mm stroke, you must use external guides to prevent rod bending and manage side loads. Finally, this specific SKU has no magnet, meaning it cannot support position sensing.
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 SAUJ100X800-50 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force rises to 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. The nominal 800 mm extend stroke can be shortened by up to 50 mm on-site using the external stop screw, giving a usable range of 750-800 mm.
No, this SKU lacks a magnet (-S) and cannot accept magnetic sensors. Furthermore, a plain cylinder does not hold load on air loss; the piston drifts and the 29 mm cushion only decelerates near the end. For vertical loads, install an external rod lock or pilot-operated check valve.
