Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20 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 SAUJ100X950-20
The AirTAC SAUJ100X950-20 is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you trim the working stroke by up to 20 mm, giving a usable range of 930-950 mm. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 1/2 inch port, an M20x1.5 rod thread, and 29 mm adjustable air cushions.
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. For sizing, a safe working load is roughly 2356 N (about 60% of the 0.5 MPa push force), translating to a 200 kg vertical lift with a 2:1 margin. Since this SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors. Basic, FA, and LB mounts are supported.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20 Is Used
Press Stroke Calibration
Finalizes contact force on large panels by dialing in the extend stroke exactly 10 mm shorter, avoiding tooling replacement.
Long-Transfer Diverter
Adjusts the pusher end position on-site to handle slightly different pallet widths without reprogramming the motion controller.
Vertical Lift Gate
Sets the precise upper travel limit for a heavy gate, using the stop screw to fine-tune the 930-950 mm opening height.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20 the Right Cylinder?
When sizing this actuator, compare adjacent bores: an 80 mm bore yields 2513 N push at 0.5 MPa, while this 100 mm unit provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires precise end-position tuning without buying a different cylinder. The 20 mm adjust window is ideal for final mechanical timing. This non-magnetic SKU cannot take sensors; add the -S suffix if you need position detection. Because the 950 mm stroke is long, always use external guides to prevent rod bending and manage side loads. Mounting is compatible with the AirTAC SC series.

- ✓ 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 SAUJ100X950-20 FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull. Push force increases 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 nominal 950 mm extend stroke can be shortened by up to 20 mm via an external stop screw, yielding a 930-950 mm usable window.
No to both. This SKU lacks the -S magnet, so it cannot accept magnetic switches. Additionally, the stop screw only sets the end position; it is not a load lock. On air loss, the piston drifts and the 29 mm cushion only decelerates near stroke end. Use an external rod lock or pilot-operated check valve for held loads.
