About the Airtac SAI50 Standard Cylinder SAI50X275CA
The AirTAC SAI50X275 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 275mm stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for mid-range industrial actuation. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that simplifies mounting and maintenance.
This unit ships with a standard carbon steel piston rod and utilizes a PT tapered port thread. Because no magnet is specified, it operates without sensor tracks; add the -S suffix if you need CMSE or DMSE switches for end-of-stroke detection.

Where the Airtac SAI50 Standard Cylinder SAI50X275CA Is Used
Package Diversion
Actuates routing gates on packaging lines where 982 N of push force easily redirects moderate-weight cartons.
Material Ejection
Pushes finished molded parts out of a lower machine bay, utilizing the full 275mm stroke to clear the work area safely.
Press Fit Subassembly
Presses bearings or pins into housings on an automated stand, relying on adjustable end cushions to soften stroke completion.
Is the Airtac SAI50 Standard Cylinder SAI50X275CA the Right Cylinder?
At 0.5 MPa, this 50mm bore yields 982 N of push force. If your assembly requires less force, stepping down to the 40mm bore provides 628 N, while moving up to the 63mm bore offers 1559 N for heavier payloads. The 275mm stroke is a standard length, so no made-to-order lead times apply.
Since the 275mm stroke exceeds 300mm? Actually at 275mm it is just under the threshold, but side-load management remains a good practice. For applications that must maintain a position without continuous air pressure, note that a standard cylinder will drift; utilize the SAIL variant with an air-released lock or an external pilot-operated check valve to hold loads safely. This model provides a true ISO 15552 mounting interface, ensuring dimensional interchangeability with other ISO 15552 profile cylinders. Pair it with a CA clevis mounting accessory for pivoting movements.
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.
