About the Airtac SAI160 Standard Cylinder SAI160AX400
The AirTAC SAI160X400 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 14074 N at 0.7 MPa, making it well-suited for moving large masses over its 400 mm stroke. The extruded aluminum barrel design omits tie-rods for a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 actuators.
Configured here with an SUS420J2 stainless steel piston rod (material code A), this model offers enhanced resistance to moisture and corrosion compared to standard carbon steel. The barrel features integrated sensor grooves on both sides for direct mounting of CMSE or DMSE switches, though a magnet must be specified separately if position detection is required.

Where the Airtac SAI160 Standard Cylinder SAI160AX400 Is Used
Heavy Stamping Presses
Provides the high 14074 N push force at 0.7 MPa required to actuate large forming presses and heavy-duty stamping dies.
Large Assembly Fixtures
Drives substantial clamping arms and positioning fixtures in automated automotive and heavy machinery assembly lines.
Pallet Diverters
Handles the robust kinetic energy needed to divert or stop fully loaded heavy industrial pallets on conveyor systems.
Is the Airtac SAI160 Standard Cylinder SAI160AX400 the Right Cylinder?
Selecting this 160 mm bore cylinder is appropriate when applications exceed the 10053 N push capacity of the 125 mm variant at 0.5 MPa but do not require the maximum 15708 N output of the 200 mm series. Operating at 0.5 MPa, the SAI160X400 yields 10053 N of push force and 9425 N of pull force. Fluid connections utilize PT tapered G3/4 ports, and standard mounting accessories include LB foot brackets, FA flanges, and TC trunnion styles.
Because the 400 mm stroke generates extended rod overhang, external guide rails should support the load to prevent side-load bending on the rod bearing. This standard actuator relies on adjustable air cushions at both ends to decelerate the piston and will not hold a load if air pressure drops; for fail-safe locking under pressure loss, specify the SAIL or BSAI variant.
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 SAI160AX400 FAQ
At an operating pressure of 0.7 MPa, the SAI160X400 generates a push force of 14074 N and a pull force of 13270 N. At 0.5 MPa, the push force is 10053 N.
Yes, the SAI160X400 is dimensionally interchangeable per ISO 15552 mounting standards. It can serve as a direct replacement for other ISO 15552 profile cylinders with matching 160 mm bore and 400 mm stroke specifications.
