Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-30S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-30S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 850mm 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 SAUJ100X850-30S
The AirTAC SAUJ100X850-30S is a double-acting, single-rod profile cylinder with an on-site stroke adjustment window. An external stop screw lets you trim the extend stroke by up to 30 mm, giving a usable working stroke of 820-850 mm. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same 100 mm bore.
This bore delivers substantial thrust: 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 of roughly 2356 N, or a 200 kg vertical lift with a 2:1 margin. It features a 1/2" port, M20x1.5 rod thread, and the -S suffix means a built-in magnet for CMSG, DMSG, or EMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 30 mm extend position for inserting components without re-engineering the entire pneumatic press fixture.
Divertor Gate Adjustment
Perfect for altering the gate reach on a packaging line to handle varying product widths on the fly.
Pallet Stop Positioning
Enables precise tuning of the stopping point for different pallet depths before the final mechanical lock engages.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-30S the Right Cylinder?
When sizing this unit, look at both neighbors and forces: the 80 mm bore offers 2513 N push at 0.5 MPa, while this 100 mm bore provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly needs final end-position tuning without buying a different cylinder. The 30 mm adjust window is ideal for fine-tuning. Mounting options include Basic, FA flange, and LB foot, with compatibility matching the AirTAC SC series. Because the stroke is 850 mm, you must use external guides to prevent rod bending and manage side loads. The -S option enables electronic or reed 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 SAUJ100X850-30S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force. This scales to 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 external stop screw allows you to shorten the extend stroke by up to 30 mm on-site, making the usable range 820-850 mm.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG position sensors. Note that the stop screw only sets the end position; it is not a load lock. A plain cylinder drifts on air loss, and the air cushion only decelerates. For secure load holding, use an external rod lock or pilot-operated check valve.
