About the Airtac SAI50 Standard Cylinder SAI50X140
The AirTAC SAI50X140 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and 140mm stroke. It delivers a robust push thrust of 982N at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks that require a specific intermediate travel distance.
This model features a standard carbon steel piston rod and a tapered PT port thread. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for easy installation of CMSE or DMSE switches if a magnet (-S) variant is added later. Adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI50 Standard Cylinder SAI50X140 Is Used
Automated Clamping
Provides reliable 982N clamping force at 0.5 MPa for securing medium-sized metal workpieces during machining operations.
Package Diverting
The 140mm stroke offers the exact reach needed to push products between adjacent conveyor lanes in sorting systems.
Material Lifting
Raises and lowers light tooling platforms with a smooth 30-800 mm/s speed range, utilizing adjustable cushions to prevent impact damage.
Is the Airtac SAI50 Standard Cylinder SAI50X140 the Right Cylinder?
Choose this 50mm bore when a 40mm bore (628N at 0.5 MPa) is insufficient for your load, but an 80mm bore (2513N at 0.5 MPa) would be excessive overkill. The 140mm stroke provides ample travel for automated clamping and lifting tasks.
For this specific 140mm stroke length, side-load stress on the rod bearing is minimal, but always ensure proper alignment. If your machinery experiences air pressure loss, this standard SAI cylinder will drift and cannot hold a load; for fail-safe position holding, consider the SAIL (lock) variant or an external rod lock. To replace an existing unit, match the 50mm bore, 140mm stroke, G1/4 port, and your required mounting accessory (like FA flange or TC trunnion).
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 SAI50X140 FAQ
At a standard 0.5 MPa operating pressure, the SAI50X140 provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
Yes, the SAI50X140 is a genuine AirTAC profile cylinder that is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 cylinders, provided you match the 50mm bore, 140mm stroke, and G1/4 port.
