Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100S
The AirTAC Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100S is a genuine double-acting profile-type standard air cylinder with a Ø80mm bore and 100mm stroke, 3/8" 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 SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100S
The AirTAC SAUJ80X100-100S is a double-acting, single-rod profile cylinder with an on-site adjustable extend stroke. An external stop screw lets you shorten the 100 mm maximum stroke by up to 100 mm, giving a usable extend window of 0-100 mm. This bore delivers 2513 N push and 2268 N pull at 0.5 MPa, with a 3/8" port and M20x1.5 rod thread. The extruded aluminum profile barrel is noticeably shorter than an ISO 15552 unit of the same bore.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG switches. For sizing, the safe working load is roughly 1508 N (about 60% of the 2513 N push at 0.5 MPa), translating to a 128 kg vertical lift with a 2:1 safety margin. The 28 mm adjustable air cushions decelerate the load near the ends, but the stop screw only sets the end position—it is not a load lock.

Where the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100S Is Used
Variable Depth Spotting
Adjusts the extend stroke on-site to machine blind holes of varying depths without changing tooling setups.
Variable Height Sealing
Trims the extend endpoint to press carton seals precisely, accommodating fluctuating package flap tolerances.
Adjustable Diverting Arm
Tunes the actuator reach on a conveyor line to deflect different product widths accurately.
Is the Airtac SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100S the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to a 100 mm bore provides 3927 N. Choose the SAUJ over a fixed SAU when your machine assembly requires field tuning of the extend endpoint rather than relying on a machined external stop. The -100 adjust window is ideal for prototyping or accommodating varying material thicknesses. Basic, FA, and LB mounts are available, sharing compatibility with the AirTAC SC series. The -S magnet enables electronic or reed sensing. For strokes at or over 300 mm, use a guide rail to prevent side-load wear.
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 SAUJ80 Adjustable Stroke Cylinder SAUJ80X100-100S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. Push force is 3518 N at 0.7 MPa, 4523 N at 0.9 MPa, and 513 kgf maximum at 1.0 MPa. The nominal 100 mm extend stroke can be shortened by up to 100 mm via the external stop screw, yielding a 0-100 mm usable window.
The -S suffix indicates a built-in piston magnet for mounting CMSG, DMSG, or EMSG sensors along the barrel for position detection. The cylinder does not hold a load on air loss; the cushion only decelerates, and the stop screw sets position but is not a brake. Use an external rod lock or pilot-operated check valve for secure load holding.
