The AirTAC Airtac SAI50 Standard Cylinder SAI50AX45 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 45mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI50X45 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 45 mm stroke is optimal for short-travel clamping and indexing tasks. Built with an extruded aluminum barrel, this tie-rod-less design ensures direct dimensional interchangeability with other ISO 15552 standard cylinders.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance in mildly aggressive environments. Fluid supply connects via PT tapered thread ports. Because no magnet is specified, this base unit does not support direct piston sensing via reed or solid-state switches.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Ideal for holding lightweight metal or plastic workpieces securely during secondary machining operations.
Provides rapid actuation for pusher arms sorting small to medium packages on packaging lines.
Reliably drives small access gates or machine safety covers that require a compact 45 mm travel distance.
Selecting this 50 mm bore over the smaller 40 mm variant upgrades your thrust from 628 N to 982 N at 0.5 MPa, while stepping up to a 63 mm bore yields 1559 N. The 45 mm stroke keeps the assembly highly compact, minimizing mechanical envelope footprint.
If your workflow requires the piston to hold a load during a complete loss of air pressure, note that the standard adjustable air cushions only decelerate the rod near stroke end. For secure position holding, consider the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock cylinder.
Quick checklist
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force.
Yes. The SAI50X45 is built to the ISO 15552 mounting interface standard, making it dimensionally interchangeable with equivalent profile cylinders from other manufacturers.
