About the Airtac SAI50 Standard Cylinder SAI50AX5
The AirTAC SAI50X5 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 5mm stroke. It delivers 982 N of push force at 0.5 MPa, making it highly effective for brief, high-impact clamping or ejecting tasks. This specific configuration is built with a SUS420J2 stainless steel rod and utilizes PT tapered port threads.
Because the 5mm stroke falls below standard increments, it is manufactured as a made-to-order unit. The extruded aluminum barrel includes dual sensor grooves for CMSE or DMSE switches, though this particular SKU does not include the internal magnet required to trigger them. As a genuine AirTAC component, it ensures strict dimensional interchangeability with other ISO 15552 actuators.

Where the Airtac SAI50 Standard Cylinder SAI50AX5 Is Used
Precision Part Clamping
Ideal for securing heavy machined components during milling or drilling, using its 982 N push force to hold parts firmly in a fixture.
Product Ejection
Provides a rapid, short-impact burst to push finished goods off a conveyor belt into packaging chutes without extending into the work area.
Press Assembly
Executes short travel pressing operations, such as seating bearings or pins, where a full 25mm stroke would be inefficient and slow.
Is the Airtac SAI50 Standard Cylinder SAI50AX5 the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm bore yields a significant force jump from 628 N to 982 N at 0.5 MPa, providing extra holding power for demanding short-stroke operations. Conversely, stepping up to the 63mm bore offers 1559 N if your fixture requires even greater thrust. For a 5mm stroke, side-load bending is negligible, so standard mounting accessories like FA or FB flanges are sufficient.
Note that the adjustable air cushions at both ends provide end-of-stroke deceleration but do not lock the piston. If the air supply is dropped, the cylinder cannot hold a suspended load; apply an external check valve or select the SAIL series for pneumatic locking. To replace an existing actuator, match the 50mm bore, 5mm stroke, G1/4 PT port, and desired mounting accessory.
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 SAI50 Standard Cylinder SAI50AX5 FAQ
At a standard 0.5 MPa operating pressure, this 50mm bore cylinder generates 982 N of push force and 825 N of pull force. It can reach up to 1767 N push force at 0.9 MPa.
Yes, the SAI50X5 is a genuine AirTac profile cylinder built to ISO 15552 dimensional standards. It serves as a direct replacement for other ISO 15552 cylinders, provided you match the 50mm bore, G1/4 port, and mounting hardware.
