Airtac SAU Standard Air Cylinder SAU100X155
The AirTAC Airtac SAU Standard Air Cylinder SAU100X155 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 155mm 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 SAU100X155
The AirTAC SAU100X155 is a double-acting profile-type cylinder engineered for heavy-duty automation. It delivers a robust 3927 N push and 3681 N pull at 0.5 MPa, scaling up to 7068 N at 0.9 MPa. Its extruded aluminum barrel design is purposefully shorter than an ISO 15552 cylinder of the same bore, offering a distinct spatial advantage in tight machine frames. This specific unit features a non-standard 155 mm made-to-order stroke.
Equipped with a 1/2" air port and a 25 mm hard-chrome plated rod, it handles substantial loads efficiently. For practical sizing, plan for a safe working load of roughly 2356 N at 0.5 MPa to account for seal friction, which translates to lifting about 200 kg vertically with a 2:1 safety margin. The standard TPU seals operate from -20 to +70 C, but a Viton H option extends this to 150 C for high-heat environments. Note that this SKU lacks a magnet, so CMSG/DMSG/EMSG sensors cannot be used.

Where the Airtac SAU Standard Air Cylinder SAU100X155 Is Used
Heavy Press Demolding
Generates 5497 N of push force at 0.7 MPa to break loose stubborn injection-molded parts from heavy tooling, utilizing the compact profile to fit within tight press enclosures.
Palletized Load Shifting
Leverages the 200 kg vertical lift capacity to index heavy palletized goods vertically on a conveyor line, ensuring smooth deceleration via the adjustable 29 mm cushions.
Automated Assembly Clamping
Secures large steel chassis components during robotic welding, relying on the 1/2" port for rapid high-volume air flow and the SC-series FA flange for rigid mounting.
Is the Airtac SAU Standard Air Cylinder SAU100X155 the Right Cylinder?
When sizing this actuator, compare its 3927 N push force at 0.5 MPa against the neighboring bores: the 80 mm bore provides 2513 N, while the 100 mm sits comfortably above it. If 155 mm is not strictly required, standard strokes like 150 mm or 160 mm are more readily available. Because this is a non-standard 155 mm stroke, expect a made-to-order lead time. Mounting is highly flexible using AirTAC SC-series accessories, including LB foot, FA/FB flange, and CA/CB clevis brackets.
Keep in mind that a standard double-acting cylinder will drift if air pressure drops or the valve is centered; the adjustable 29 mm air cushions at both ends only decelerate the piston near stroke end and do not function as a locking brake. To safely suspend a load, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 SAU100X155 FAQ
This 100 mm bore cylinder 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 it pushes 5497 N, and at 0.9 MPa it pushes 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
It is strictly compatible with AirTAC SC-series mounting accessories (LB, FA, CA), not ISO 15552 brackets. Additionally, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG magnetic sensors.
