About the Airtac SAI100 Standard Air Cylinder SAI100X550S
The AirTAC SAI100X550-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, this 100mm bore unit utilizes an extruded aluminum barrel without tie-rods for a rigid yet streamlined structure. The 550mm stroke provides ample extension for mid-length linear actuation tasks.
This variant includes a standard magnet for proximity sensing and features a carbon steel piston rod for high tensile strength under load. The barrel incorporates dual sensor grooves designed specifically for CMSE and DMSE switches, ensuring flexible mounting for position feedback. For environments requiring elevated temperatures, the seal configuration can be upgraded from standard TPU to Viton (H) or NBR (N).

Where the Airtac SAI100 Standard Air Cylinder SAI100X550S Is Used
Heavy-Duty Pressing
Applies 5497 N of force at 0.7 MPa to seat bearings, stamp components, or form light-gauge materials over a 550mm extension.
Pallet Diverting
Extends 550mm to push heavy pallets off a high-throughput conveyor line, utilizing the integrated magnet for mid-stroke confirmation.
Large Gate Actuation
Operates substantial machine guarding or material flow gates where the 100mm bore provides the necessary torque to overcome friction.
Is the Airtac SAI100 Standard Air Cylinder SAI100X550S the Right Cylinder?
Selecting this 100mm bore cylinder is ideal when an application demands thrust exceeding the 3518 N provided by the smaller 80mm variant at 0.7 MPa, but does not yet require the massive 8590 N output of the 125mm class. Its G1/2 PT tapered port accommodates high airflow to maintain velocity across the 550mm extension.
Because the 550mm stroke exceeds the 300mm threshold, the unsupported rod length is susceptible to bending under side loads. Implementing an external guide rail or choosing a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear. Note that the standard adjustable air cushions at both ends decelerate the piston near stroke end but do not hold the load; if pneumatic pressure is lost, the rod will drift. For dead-end position holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100mm bore, 550mm stroke ISO cylinder, compatible with FA, LB, CA, and TC mounting accessories.
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 SAI100X550S FAQ
At a standard operating pressure of 0.7 MPa, this 100mm bore cylinder generates 5497 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
Yes. The SAI100X550-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other 100mm bore, 550mm stroke ISO 15552 profile cylinders, matching the G1/2 port and standard mounting dimensions.
