Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20S
The AirTAC Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20S 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 SAUJ100X950-20S
The AirTAC SAUJ100X950-20S is a double-acting single-rod profile cylinder with an on-site extend-stroke trim window. An external stop screw lets you shorten the 950 mm nominal travel by up to 20 mm, yielding a usable 930-950 mm range without buying a new actuator. The extruded aluminum profile barrel makes it shorter than an ISO 15552 cylinder of the same bore.
This 100 mm bore uses a 1/2" port and delivers serious thrust: 3927 N push and 3681 N pull at 0.5 MPa, scaling to 7068 N at 0.9 MPa. For sizing, the safe working load is roughly 2356 N (about 60% of the 0.5 MPa push), and it can vertically lift around 200 kg with a 2:1 safety margin. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG switches.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20S Is Used
Large Press Feeders
Pushing heavy blanks into a hydraulic press where the final feed distance needs exact 20 mm field tuning to match material thickness variations.
Pallet Transfer Stops
Halting oversized pallets on a roller line, requiring a robust 100 mm bore and adjustable end-position to dial in the stopping point perfectly.
Heavy Lift Gates
Actuating large diverter gates that route heavy freight, using the magnetic piston to confirm gate position and the stop screw for timing.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X950-20S the Right Cylinder?
When sizing, step down to an 80 mm bore (2513 N push @0.5 MPa) to save air if the load allows, or keep this 100 mm unit for heavy cycles. The 20 mm adjust window is ideal for final machine timing without machining a hard stop. Choose FA flange or LB foot mounts, compatible with the AirTAC SC series. Because the 950 mm stroke is long, use an external guide to prevent rod bending and side-load damage. The -S magnet enables electronic or reed sensing. This cylinder beats a fixed SAU plus external stop by integrating the adjustment cleanly into the profile body.

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 SAUJ100X950-20S FAQ
It delivers 3927 N push and 3681 N pull at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa. The theoretical max is 801 kgf at 1.0 MPa. The external stop screw shortens the 950 mm extend stroke by up to 20 mm on-site, giving a 930-950 mm range. It uses a 1/2" port and a 29 mm adjustable air cushion.
The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG switches. Note that a plain cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates near stroke end. The stop screw sets end position but is not a load lock. For held loads, use an external rod lock or pilot-operated check valve.
