About the Airtac SAI40 Standard Air Cylinder SAI40X170S
The AirTAC SAI40X170-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting. Delivering a push force of 879 N at 0.7 MPa, this 40 mm bore unit is built to handle demanding actuation tasks. The 170 mm stroke provides the extended travel needed for indexing, clamping, and lifting operations.
This variant includes a magnetic piston (-S) for position detection using CMSE or DMSE reed switches, which seat neatly into the dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod offers high tensile strength for industrial environments, while the PT tapered port threads guarantee a tight, leak-free pneumatic connection.

Where the Airtac SAI40 Standard Air Cylinder SAI40X170S Is Used
Component Clamping
Secures irregular workpieces during machining operations using 628 N of thrust at 0.5 MPa to hold parts firmly against the fixture.
Package Diversion
Extends 170 mm to push cartons off a main conveyor belt, utilizing the magnetic piston to confirm stroke completion via sensors.
Pallet Lifting
Raises lightweight pallets or tote bins to an ergonomic working height, taking advantage of the robust carbon steel rod.
Is the Airtac SAI40 Standard Air Cylinder SAI40X170S the Right Cylinder?
If your application requires less force, stepping down to a 32 mm bore yields 563 N at 0.7 MPa, whereas upgrading to a 50 mm bore provides 1374 N for heavier payloads. Because 170 mm is a non-standard increment, verify your exact dead-length space constraints before ordering.
This cylinder is a direct drop-in replacement for any ISO 15552 profile cylinder with a 40 mm bore, 170 mm stroke, PT porting, and matching mounting accessories. If the machinery loses air pressure, the piston will drift and cannot hold a load; integrate an external pilot-operated check valve if position holding is mandatory.
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 SAI40 Standard Air Cylinder SAI40X170S FAQ
At an operating pressure of 0.7 MPa, the cylinder generates 879 N of push force and 739 N of pull force. The maximum theoretical force at 1.0 MPa is 128 kgf.
Yes, the SAI40X170-S is dimensionally interchangeable per ISO 15552. You can swap it directly with other 40 mm bore ISO 15552 profile cylinders that share the same 170 mm stroke and mounting interface.
