Airtac SAU Standard Air Cylinder SAU100X135
The AirTAC Airtac SAU Standard Air Cylinder SAU100X135 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 135mm 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 SAU100X135
The AirTAC SAU100X135 is a double-acting profile-type cylinder featuring a 100 mm bore and 135 mm stroke. It supplies a substantial 3927 N of push force at 0.5 MPa. Built with an extruded aluminum barrel, this unit is significantly shorter than an ISO 15552 cylinder of the same bore, offering a major space advantage in tight machine layouts. It operates on a 1/2" port and features a 25 mm carbon steel rod with an M20x1.5 thread.
For practical sizing, plan for a safe working load of roughly 2356 N, which accounts for seal friction and smooth travel at 0.5 MPa. This translates to lifting about 200 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensor switches. You can also specify Viton H seals if your application requires withstanding temperatures up to 150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X135 Is Used
Heavy Stamp Press Feed
Drives robust clamping arms in automated metal stamping lines where the 3927 N push force securely holds heavy coil stock.
Pallet Lift Station
Elevates loaded pallets in packaging zones, utilizing the 200 kg vertical lift capacity to raise goods to conveyor height.
Injection Mold Ejection
Pushes thick molded plastic parts out of heavy industrial presses, benefiting from the compact profile to fit within tight machine frames.
Is the Airtac SAU Standard Air Cylinder SAU100X135 the Right Cylinder?
When sizing this 100 mm bore actuator, compare it against adjacent bores: a 63 mm unit yields 1559 N push at 0.5 MPa, while there is no larger standard SAU bore, making this the top force tier at 801 kgf theoretical maximum. If your mechanism relies on gravity, remember that a standard cylinder drifts when air is removed or a valve is centered; the adjustable 29 mm air cushions only decelerate the piston near stroke end and do not function as a locking brake. To sustain a suspended load, integrate an external rod lock or a pilot-operated check valve. Mounting hardware matches the AirTAC SC series, allowing you to use LB foot brackets, FA/FB flanges, or CA/CB clevises.
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 SAU100X135 FAQ
This 100 mm bore cylinder features a 1/2" port and delivers 3927 N push and 3681 N pull at 0.5 MPa. At 0.7 MPa the push force is 5497 N, and the theoretical maximum force is 801 kgf at 1.0 MPa.
No, the SAU is a compact profile cylinder and is not dimensionally interchangeable with ISO 15552 standards. You must use AirTAC SC-series mounting accessories, such as LB foot, FA/FB flange, or CA/CB clevis brackets. Additionally, this non-S SKU lacks a magnet for sensors.
