Airtac SAU Standard Air Cylinder SAU100X312SN
The AirTAC Airtac SAU Standard Air Cylinder SAU100X312SN is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 312mm 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 SAU Standard Air Cylinder SAU100X312SN
The AirTAC SAU100X312SN is a double-acting profile-type cylinder with a 100 mm bore and 312 mm stroke. Its extruded aluminum barrel makes it shorter and more compact than an ISO 15552 cylinder of the same bore, providing a space-saving footprint for tight machinery. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, operating on a 1/2" port with a 25 mm rod and M20x1.5 thread.
For practical sizing, plan for a safe working load of about 2356 N (60% of the 0.5 MPa push figure) to account for seal friction and smooth travel. This translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors, while the NBR (N) seals handle standard -20 to +70 C environments. An adjustable 29 mm air cushion decelerates the piston at both stroke ends.

Where the Airtac SAU Standard Air Cylinder SAU100X312SN Is Used
Heavy-Duty Stamping Press
Drives a 150 kg die set in an automotive component stamping line, utilizing the 3927 N push force at 0.5 MPa to form sheet metal reliably.
Pallet Dispenser Mechanism
Actuates a 312 mm stroke to push empty pallets into a packaging conveyor, where the compact profile length saves valuable floor space.
Vertical Lift Gate
Raises a 180 kg material lift gate using the 200 kg vertical lift capacity, requiring external guide rails to stabilize the long 312 mm extension.
Is the Airtac SAU Standard Air Cylinder SAU100X312SN the Right Cylinder?
When sizing this 100 mm bore unit, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, whereas this 100 mm model provides 3927 N. Since 100 mm is the largest standard SAU bore, moving up in force requires a non-standard or different cylinder family entirely. The 312 mm stroke requires careful mounting to prevent rod bending; always use external guide rails to support heavy loads and minimize side-load wear. Mounting hardware is compatible with AirTAC SC series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The adjustable air cushion only slows the piston near the end of travel and does not function as a braking or locking mechanism. If your application requires holding a vertical load securely during an air loss event, install an external rod lock or a pilot-operated check valve.
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 SAU Standard Air Cylinder SAU100X312SN FAQ
This 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. At 0.7 MPa, the push force is 5497 N, reaching 7068 N at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, has a proof pressure of 1.5 MPa, and runs at speeds of 30-800 mm/s.
No, it is not an ISO 15552 cylinder and shares its mounting footprint only with the AirTAC SC series (LB, FA, FB, CA, CB accessories). The SAU100X312SN includes a built-in magnet (-S) for use with CMSG, DMSG, or EMSG sensor switches that fit directly into the extruded profile barrel groove.
