About the Airtac SAI50 Standard Cylinder SAI50X275
The AirTAC SAI50X275 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N and a pull force of 825 N at 0.5 MPa. Its 275 mm stroke is well-suited for mid-range linear actuation tasks requiring reliable mid-tier thrust. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops seamlessly into standardized ISO 15552 mounting interfaces.
This configuration features a standard carbon steel piston rod and PT tapered G1/4 port threads. Because a magnet is not specified, it does not include built-in sensor tracks for CMSE or DMSE switches. For operations experiencing thermal extremes, users can explore alternative seal options like Viton (H) for high-temperature resistance instead of the standard TPU seals.

Where the Airtac SAI50 Standard Cylinder SAI50X275 Is Used
Component Clamping
Secures medium-sized machined parts during milling or drilling operations, utilizing its 982 N push force to hold workpieces firmly against fixture stops.
Package Diverting
Actuates routing gates on packaging lines, pushing totes or cartons laterally with precise 275 mm travel to sort product flow.
Assembly Pressing
Drives small bushings or pins into housings on automated assembly lines, providing consistent downward force without needing a full hydraulic press.
Is the Airtac SAI50 Standard Cylinder SAI50X275 the Right Cylinder?
With a 982 N thrust at 0.5 MPa, this 50 mm bore fits neatly between the lighter 40 mm bore (628 N) and the heavier 63 mm bore (1559 N). Choose the SAI50X275 when your application demands more power than a 40 mm bore provides but lacks the space or air capacity for a 63 mm unit. Because the 275 mm stroke exceeds the 250 mm standard increment, verify your overall length envelope. This cylinder uses a PT G1/4 port and supports standard ISO 15552 mounting accessories like FA flange or LB foot brackets.
At 275 mm of travel, the unsupported piston rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, guide the load externally using a linear rail or select a guided cylinder variant. Additionally, the adjustable air cushions at both ends only decelerate the piston near stroke limits; they do not hold loads. If your process requires position retention upon air loss, integrate an external pilot-operated check valve or specify the SAIL locking variant.
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 SAI50X275 FAQ
The SAI50X275 generates a push force of 982 N and a pull force of 825 N when operated at 0.5 MPa. If you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X275 is a true profile-type ISO 15552 cylinder. Its standardized mounting dimensions and G1/4 PT ports make it dimensionally interchangeable with other ISO 15552 profile cylinders, allowing for seamless direct replacement.
