About the Airtac SC50 Standard Cylinder SC50X15SH
The AirTAC SC50X15SH is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a compact 15 mm stroke, built for short-throw clamping, ejecting, and positioning tasks. Its built-in magnet (-S) allows direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the tie-rod barrel for reliable end-of-stroke detection, while the Viton (FKM) seals (-H) shift the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU would degrade.
At the standard 0.5 MPa supply, this cylinder pushes with 982 N and pulls with 825 N; at the maximum operating pressure of 0.9 MPa the thrust reaches 1767 N. The 20 mm diameter piston rod, PT1/4 port, and 21 mm adjustable air cushion are standard for the 50 mm bore series. This model is a genuine AirTAC SC tie-rod cylinder, engineered for high cycle counts and easy maintenance in industrial automation.

Where the Airtac SC50 Standard Cylinder SC50X15SH Is Used
Hot-Environment Clamping
The Viton seals and 15 mm stroke make this cylinder ideal for pneumatic clamping fixtures in ovens, autoclaves, or near heat sources up to 150 °C, where standard seals would fail.
Sensor-Monitored Ejection
With the built-in magnet, CMSG sensors confirm full extension and retraction on a short-stroke ejector station, preventing tooling crashes in automated assembly cells.
High-Temp Part Stops
Deploy the SC50X15SH as a heat-resistant part stop on conveyors passing through drying or curing tunnels, where the 982 N push force securely halts product carriers.
Is the Airtac SC50 Standard Cylinder SC50X15SH the Right Cylinder?
Choose the SC50 bore when your application needs roughly 1000 N of push force at 0.5 MPa. If you need less force and a smaller footprint, step down to the SC40 (628 N push at 0.5 MPa); for heavier loads, the SC63 delivers 1559 N at the same pressure. The 15 mm stroke is a standard length, ideal for space-constrained fixtures.
For replacement, match five points: 50 mm bore, 15 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal material (-H) for high-temperature operation. This tie-rod cylinder is dimensionally shorter than an ISO 15552 profile, so it is not a drop-in replacement for that standard—verify the body length (150 mm) and mounting dimensions against your existing setup.
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 SC50 Standard Cylinder SC50X15SH FAQ
At 0.7 MPa (7 bar) the SC50X15SH delivers a theoretical pushing force of 1374 N. The pulling force at the same pressure is 825 N, accounting for the 20 mm rod diameter. For applications needing precise force control, use a regulated pressure supply and factor in a safety margin for friction losses.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. The SC50 body length A is 150 mm, which will not match ISO 15552 mounting dimensions. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching bore, stroke, PT ports, magnet option, and seal material.
