Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-50
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-50 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 SAUJ100X950-50
The AirTAC SAUJ100X950-50 is a double-acting, single-rod profile cylinder with an on-site stroke adjustment window. An external stop screw lets you shorten the extend stroke by up to 50 mm, giving a usable range of 900-950 mm. The 950 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 at each end. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore generates 3927 N push and 3681 N pull at 0.5 MPa, peaking at 7068 N push at 0.9 MPa. A computed buyer insight: the safe working load is roughly 2356 N (about 60 percent of the 0.5 MPa push), translating to a 200 kg vertical lift with a 2:1 margin. Choose this adjustable unit over a fixed SAU plus external stop to save mounting space. It operates at 0.15-1.0 MPa and 30-800 mm/s. This SKU lacks a magnet, so it cannot take a sensor.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-50 Is Used
Material Transfer Stops
Fine-tune the 900-950 mm extend position on-site to match varying pallet sizes without remachining hard stops.
Press Fit Calibration
Dial in the exact 50 mm window during setup to perfect part seating depth on long-stroke assembly lines.
Packaging Pusher Arms
Adjust the extend end point quickly when changing carton formats, using the 3927 N push force to move heavy loads.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-50 the Right Cylinder?
Size both ways: the 80 mm neighbor yields 2513 N push at 0.5 MPa, while this 100 mm bore delivers 3927 N. If you need less force, drop to 80 mm; if you need more, confirm a larger custom solution. Pick the SAUJ over a fixed SAU when you need on-site extend tuning without adding a separate external stop. The 50 mm adjust window is ideal for final machine timing. Mounting is Basic, FA flange, or LB foot, sharing compatibility with the AirTAC SC series. Because the stroke is 950 mm, you must use external guides to prevent rod bending and manage side loads. This non-magnet SKU cannot accept CMSG or DMSG 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 SAUJ100X950-50 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push rises 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 shortens the extend stroke by up to 50 mm on-site, giving a usable 900-950 mm range from the 950 mm maximum.
The external stop screw mechanically sets the extend end position but is not a load lock. A plain cylinder does not hold its load on air loss; the piston drifts and the 29 mm air cushion only decelerates near stroke end. For a held load, use an external rod lock or pilot-operated check valve. This non-magnet SKU cannot take sensors.
