Airtac SAU Standard Air Cylinder SAU100X165
The AirTAC Airtac SAU Standard Air Cylinder SAU100X165 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 165mm 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 SAU100X165
The AirTAC SAU100X165 is a double-acting profile-type cylinder with a custom 165 mm stroke, engineered to be shorter and more compact than an ISO 15552 cylinder of the same bore. It handles heavy-duty tasks with a push force of 3927 N and a pull force of 3681 N at 0.5 MPa. The extruded aluminum barrel incorporates an integrated sensor groove, though this specific SKU lacks the -S magnet and therefore cannot accept CMSG, DMSG, or EMSG reed switches. It features a 1/2 inch air port and an M20x1.5 rod-end 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 lifting scenario, this actuator can reliably lift about 200 kg when applying a 2:1 safety margin. If your machinery operates in extreme heat, you can specify the Viton H high-temperature seal option to raise the operating range from -20 to +70 C up to 0-150 C.

Where the Airtac SAU Standard Air Cylinder SAU100X165 Is Used
Heavy Stamp Press Ejection
Utilizes the 3927 N push force at 0.5 MPa to eject thick steel blanks from a hydraulic stamping press, taking advantage of the short profile to fit within the press bed.
Pallet Dispenser Pusher
Handles the 200 kg vertical lift equivalent to feed empty wooden pallets into an automated packaging line, relying on the 1/2 inch port for rapid air exchange.
Injection Mold Separation
Breaks the vacuum seal on large plastic injection molds using the 3681 N pull force at 0.5 MPa, where the custom 165 mm stroke provides the exact travel needed for part clearance.
Is the Airtac SAU Standard Air Cylinder SAU100X165 the Right Cylinder?
When sizing this actuator, evaluate the force brackets of adjacent bores to ensure optimal performance. Stepping down to an 80 mm bore reduces the 0.5 MPa push force to 2513 N, while stepping up is not possible as 100 mm is the largest available SAU bore. This model features a custom 165 mm stroke, making it a made-to-order solution for specific machinery envelopes. Because the stroke is under 300 mm, standard side-load concerns are minimized, but you should still utilize the SC-series mounting accessories, such as LB foot or FA flange brackets, to secure the body rigidly.
Keep in mind that a plain cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, as the adjustable 29 mm air cushions only decelerate the rod near the end of travel and act as a brake. For suspended or gravity-loaded applications, you must integrate an external rod lock or a pilot-operated check valve. Additionally, since this SKU lacks the -S magnet, it cannot support magnetic sensing; if position feedback is required, select an SAU100X165-S variant instead.
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 SAU100X165 FAQ
The SAU100X165 delivers 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, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 100 mm bore, a custom 165 mm stroke, a 1/2 inch air port, an M20x1.5 rod thread, and operates at speeds between 30-800 mm/s.
No, the SAU is a compact profile cylinder and is not dimensionally interchangeable with ISO 15552 standards. Mounting accessories must be from the AirTAC SC series, such as LB foot, FA flange, or CA clevis brackets. Additionally, this specific SKU does not include a magnet (-S), so it cannot accept CMSG, DMSG, or EMSG sensors for position detection.
