Airtac SAU Standard Air Cylinder SAU100X5
The AirTAC Airtac SAU Standard Air Cylinder SAU100X5 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 5mm 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 SAU100X5
The AirTAC SAU100X5 is a double-acting profile-type cylinder engineered for high-force tasks in tight machine envelopes. It is purposefully shorter than an ISO 15552 cylinder of the same 100 mm bore, yielding a distinct space advantage without sacrificing power. It delivers a push force of 3927 N and a pull force of 3681 N at 0.5 MPa, utilizing a 1/2" air port and a 25 mm carbon steel rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of about 2356 N, which accounts for seal friction at 0.5 MPa. In a vertical lift scenario, this translates to lifting roughly 200 kg with a 2:1 safety margin. This specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG, or EMSG reed switches for position sensing. If your assembly requires heat resistance, the standard TPU seals can be swapped for Viton H to handle environments up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X5 Is Used
Heavy Stamping Press
Provides intense 3927 N push force for short 5 mm clamping strokes in automotive metal forming, ensuring rigid holding without excessive cylinder length.
Injection Molding Ejector
Delivers rapid high-force ejection of molded parts. The compact profile fits neatly within the tight frame of large molding machinery.
Pneumatic Riveting Clamp
Applies concentrated 200 kg vertical holding force for riveting thick steel plates, where the short 5 mm stroke maximizes structural stiffness.
Is the Airtac SAU Standard Air Cylinder SAU100X5 the Right Cylinder?
When sizing this unit, evaluate your force requirements carefully. Stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, whereas moving up is impossible as 100 mm is the largest SAU option. This SAU100X5 variant has no -S magnet, so it is incompatible with magnetic sensors; confirm if your control system requires position feedback before selecting this specific SKU. The 5 mm stroke is extremely short, meaning side-load risks from rod bending are negligible, but you must still ensure rigid mounting using compatible AirTAC SC-series accessories like LB foot or FA flange brackets.
Remember that a standard double-acting cylinder will drift if air pressure is lost or the valve is centered. The integrated adjustable air cushion at both ends only decelerates the piston near the stroke limits and does not function as a braking mechanism. To safely suspend a load during an emergency stop or air loss, integrate an external pilot-operated check valve or a dedicated rod lock.
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 SAU100X5 FAQ
The SAU100X5 features a 1/2" air port and generates 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. The theoretical maximum force is 801 kgf at 1.0 MPa.
No, it is not an ISO 15552 cylinder and uses AirTAC SC-series mounting accessories like FA flanges or CA clevis. Additionally, this SKU lacks the -S magnet, so it cannot accept CMSG or DMSG magnetic sensors.
