Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 950mm 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 SAUJ100X950-100S
The AirTAC SAUJ100X950-100S is a double-acting single-rod profile cylinder with an external stop screw that lets you trim the extend stroke on-site by up to 100 mm. The 950 mm nominal stroke is the maximum, yielding a usable extend window of 850 to 950 mm. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions at each end. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder 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 push at 0.9 MPa. A practical computed insight sets the safe working load around 2356 N (about 60 percent of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 200 kg with a 2:1 margin. The -S suffix means a built-in piston magnet is present for CMSG, DMSG, or EMSG position switches. For high-heat environments up to 150 C, Viton H seals are available.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100S Is Used
Large Press Dwell Adjustment
Allows operators to fine-tune the 100 mm extend window on-site for varying material thicknesses in a heavy forming press without changing tooling.
Palletizer Tier Positioning
Provides adjustable extend stops for stacking different pallet heights, using the built-in magnet to confirm the end position.
Heavy Divert Gate Stroke
Accommodates on-site changes to the divert distance on a high-capacity sorting line, ensuring the gate clears oversized loads.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-100S the Right Cylinder?
Size this 100 mm bore against the neighboring 80 mm option: the 80 mm yields 2513 N push at 0.5 MPa, while this 100 mm provides 3927 N at the same pressure, making it the right pick when you need that extra lifting margin. Choose the SAUJ over a fixed SAU when your machine assembly requires field-tuning of the end position rather than relying on a machined external stop. The 100 mm adjust window is generous, letting you dial in the exact extend length between 850 and 950 mm. Basic, FA flange, and LB foot mountings are available, sharing compatibility with the AirTAC SC series. Because the -S magnet is present, you can directly mount reed or electronic sensors. With a long 950 mm stroke, you must support the load with external guides to prevent rod bending and manage side loads.
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 SAUJ100X950-100S FAQ
This 100 mm bore cylinder provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, and 7068 N push at 0.9 MPa, with a theoretical max of 801 kgf at 1.0 MPa. The external stop screw allows you to shorten the 950 mm maximum extend stroke by up to 100 mm, giving a usable range of 850 to 950 mm.
The external stop screw mechanically sets the extend end position but is not a load lock. A plain cylinder drifts on air loss or when the valve is centered; the 29 mm air cushions only decelerate the piston near the end of travel. To hold a load securely, you must add an external rod lock or a pilot-operated check valve.
