Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-50
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-50 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 SAUJ100X850-50
The AirTAC SAUJ100X850-50 is a double-acting, single-rod profile cylinder with an external stop screw that lets you shorten the extend stroke on-site by up to 50 mm. The nominal 850 mm stroke is the maximum, yielding a usable range of 800-850 mm. It features a hard-anodized extruded aluminum barrel, making it shorter than an ISO 15552 cylinder of the same 100 mm bore. The 1/2" port and M20x1.5 rod thread handle serious pneumatic flow.
This 100 mm bore generates a push of 3927 N and pull of 3681 N at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. For design safety, expect a working load around 2356 N, which translates to a vertical lift capacity of roughly 200 kg with a 2:1 margin. It includes 29 mm adjustable air cushions at each end. Note this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-50 Is Used
Long-Reach Press Damping
Needs precise extend end-position tuning to accommodate varying material thicknesses without reordering the actuator.
Pallet Transfer Stopper
Requires field adjustment of the stop length to handle different pallet footprints on the same line.
Heavy Load Diversion
Demands a robust 200 kg vertical lift capacity with an adjustable stroke window for multi-size package routing.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X850-50 the Right Cylinder?
When sizing this unit, compare it against the 80 mm bore (2513 N push at 0.5 MPa) if your load is lighter, or step up if you need more. Choose the SAUJ over a fixed SAU when your machine assembly requires field-tuning of the end position; the 50 mm window saves you from buying a new cylinder if the stroke needs slight reduction. Mounting options include Basic, FA flange, and LB foot, sharing compatibility only with the AirTAC SC series. Because the 850 mm stroke is long, always use external guides to prevent rod bending and manage side loads. Finally, this non-magnetic SKU 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 SAUJ100X850-50 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull; at 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical max is 801 kgf at 1.0 MPa. The external stop screw allows you to shorten the extend stroke by up to 50 mm, giving a usable range of 800-850 mm from the 850 mm maximum.
No to both. The stop screw sets the end position but is not a load lock; without live air the piston drifts and the 29 mm cushion only decelerates. For holding a load use an external rod lock or pilot-operated check valve. Additionally, this SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.
