Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75 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 SAUJ100X800-75
The AirTAC SAUJ100X800-75 is a double-acting, single-rod profile cylinder with an on-site extend stroke adjustment. An external stop screw lets you trim the 800 mm nominal stroke by up to 75 mm, yielding a usable 725 to 800 mm window. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions. The extruded aluminum profile barrel is shorter than an ISO 15552 unit of the same bore.
This 100 mm 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 sets the safe working load around 2356 N (60% of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSG or DMSG sensors. For high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75 Is Used
Large Press Dwell Tuning
Allows operators to fine-tune the 75 mm extend window on-site to perfectly set the dwell position for heavy pressing tasks without swapping actuators.
Pallet Stop Positioning
Ideal for adjusting the end stop on a heavy-duty conveyor line where varying pallet dimensions require slight on-site stroke shortening.
Heavy Lift Gate Control
Provides the exact extend length needed for large material lift gates, using the 29 mm cushion to decelerate massive loads smoothly.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X800-75 the Right Cylinder?
When sizing this unit, look at both neighbors and the 0.5 MPa force. The 80 mm bore gives 2513 N push, while this 100 mm bore yields 3927 N; stepping up is necessary if your payload exceeds 200 kg. Choose the SAUJ over a fixed SAU when you need final end-position tuning during machine commissioning without buying a new cylinder. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. Because the 800 mm stroke is long, always use an external guide to prevent rod bending and manage side loads. Finally, this non-magnetic SKU cannot accept position sensors.
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 SAUJ100X800-75 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 a theoretical max of 801 kgf at 1.0 MPa. The 800 mm nominal extend stroke can be shortened by up to 75 mm via the external stop screw, giving a 725 to 800 mm working range.
This SKU lacks a -S magnet, so it cannot take magnetic switches. A plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates near stroke end. For a locked load, use an external rod lock or pilot-operated check valve.
