Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40 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 SAUJ100X800-40
The AirTAC SAUJ100X800-40 is a double-acting single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 40 mm, giving a usable range of 760-800 mm. The 800 mm nominal length is the maximum travel. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
This 100 mm bore unit delivers 3927 N push and 3681 N pull at 0.5 MPa, reaching 7068 N at 0.9 MPa. The extruded aluminum profile is shorter than an ISO 15552 cylinder of the same bore. For sizing, the safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa push force), and it can vertically lift around 200 kg with a 2:1 margin. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40 Is Used
Large Press Tonnage
Demands exact bottom-dead-center positioning. The 40 mm stop screw trims the extend stroke to perfect the crush distance on heavy forming tools.
Pallet Diverter Arm
Requires field tuning to match varying pallet widths. The external stop adjusts the diverter push distance without changing the cylinder body.
Heavy Load Pusher
Needs precise end-stop limits for indexing heavy inventory. The 100 mm bore provides 3927 N push force to shift loads reliably.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-40 the Right Cylinder?
Size this 100 mm bore against the 80 mm neighbor: the 80 mm yields 2513 N push at 0.5 MPa, while this 100 mm provides 3927 N, so step down if your load is lighter. Choose the SAUJ over a fixed SAU when you need final end-position tuning during machine commissioning. The 40 mm adjust window is ideal for minor mechanical alignment without buying a new actuator. Mounting options include Basic, FA flange, and LB foot, sharing compatibility with the AirTAC SC series. Because the stroke is 800 mm, you must use external guides to prevent rod bending and manage side loads. Finally, this non-magnetic SKU cannot take a sensor.
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 SAUJ100X800-40 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force is 5497 N at 0.7 MPa, 7068 N at 0.9 MPa, and 801 kgf at 1.0 MPa. The external stop screw shortens the extend stroke by up to 40 mm, giving a usable range of 760-800 mm. The port is 1/2 inch.
No to both. This SKU lacks a magnet, so it cannot accept magnetic switches. A plain cylinder also does not hold a load on air loss; the piston drifts and the cushion only decelerates near stroke end. For a held load, install an external rod lock or pilot-operated check valve.
