About the Airtac SAI160 Standard Cylinder SAI160AX450
The AirTAC SAI160X450 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 10053 N push force at 0.5 MPa, this 160 mm bore unit handles substantial loads over its 450 mm stroke. The extruded aluminum barrel design omits tie rods, providing a rigid yet streamlined profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly chemical washdown environments. Fluid ports feature a PT tapered thread type. For applications requiring extreme heat, the standard TPU seals can be swapped for Viton (code H) to withstand elevated temperatures up to 70 C.

Where the Airtac SAI160 Standard Cylinder SAI160AX450 Is Used
Heavy Stamping Presses
Provides the 10053 N push force required to actuate large stamping dies and heavy press machinery over a 450 mm travel distance.
Automotive Assembly Jigs
Drives large structural component alignment and heavy robotic gripper assemblies where a true ISO 15552 mounting interface guarantees jig interchangeability.
Pallet Handling Systems
Indexes heavy loaded pallets through 450 mm transfer stations, utilizing the 30-500 mm/s speed range to smoothly transition bulky goods.
Is the Airtac SAI160 Standard Cylinder SAI160AX450 the Right Cylinder?
Select this 160 mm bore when a 125 mm cylinder falls short—stepping up from the 125 bore (6136 N push at 0.5 MPa) to the 160 bore provides a significant leap to 10053 N for high-inertia loads. Conversely, if your application only requires around 6000 N, dropping to the 125 bore saves physical envelope and air consumption. The 450 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
Because the stroke extends to 450 mm, the unsupported rod length increases vulnerability to side-load bending and rod-bearing wear. Implement external linear guides or choose a guided cylinder variant to prevent premature seal failure. Note that a standard SAI does not hold position upon loss of air pressure; if your fixture requires dead-stop holding without live pressure, specify the SAIL lock or BSAI clamp-lock variant. To match this footprint, ensure your replacement uses a G3/4 port, an M36x2 rod thread, and the appropriate mounting accessory like an LB foot or TC trunnion.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI160 Standard Cylinder SAI160AX450 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
Yes, the SAI160X450 is dimensionally interchangeable per ISO 15552. To ensure a seamless direct replacement, match the G3/4 port, M36x2 rod thread, and your existing mounting accessories like FA flange or TC trunnion.
