About the Airtac SAI100 Standard Air Cylinder SAI100X165S
The AirTAC SAI100X165-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore unit handles substantial payloads with precision. The 165 mm stroke provides ample extension for mid-range machinery movements. A standard carbon steel piston rod ensures high tensile strength and structural rigidity under high operating pressure.
Because this variant includes the -S magnet option, it is fully compatible with CMSE and DMSE series reed switches. These sensors mount directly into the extruded aluminum barrel's dual sensor grooves, simplifying position feedback integration. For environments requiring elevated thermal resistance, the cylinder can be specified with Viton (H) seals to withstand temperatures up to 70 C without degrading.

Where the Airtac SAI100 Standard Air Cylinder SAI100X165S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force at 0.5 MPa required to actuate mechanical stamping and forming presses securely.
Pallet Diversion
Executes 165 mm strokes to push heavy pallets onto secondary conveyor lines, utilizing the -S magnet for end-of-stroke confirmation.
Automated Clamping
Secures large fabricated workpieces within machining fixtures, using its 100 mm bore to maintain unyielding clamping pressure.
Is the Airtac SAI100 Standard Air Cylinder SAI100X165S the Right Cylinder?
Choose this 100 mm bore when a 80 mm cylinder's 2513 N push force at 0.5 MPa is insufficient for your load requirements. If your application demands less force and faster cycling, stepping down to an 80 mm bore is recommended. The 165 mm stroke is well within standard limits, avoiding the severe side-load bending risks seen in strokes over 300 mm, though external guides should still be used for heavy off-center loads.
This model features PT tapered port threads for a robust, leak-free pneumatic connection. Being a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore ISO 15552 unit using FA/FB flange or TC trunnion mounts. Remember that a standard SAI cylinder relies on continuous air pressure to hold its position; if your machine requires fail-safe load holding upon pressure loss, select the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on the adjustable air cushion.
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 SAI100 Standard Air Cylinder SAI100X165S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X165-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions for FA flange or TC trunnion accessories are fully interchangeable with other standard ISO 15552 profile cylinders of the same bore size.
