About the Airtac SC50 Standard Cylinder SC50X350H
The SC50X350H is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and 350 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads for tooling attachment.
This model is fitted with high-temperature Viton (FKM) seals, shifting the operating range from the standard -20°C up to a maximum of +150°C. The body length A is 150 mm, giving a total extended length of approximately 500 mm, and the adjustable pneumatic cushion at each end is 21 mm long to effectively decelerate the load.

Where the Airtac SC50 Standard Cylinder SC50X350H Is Used
High-Temperature Actuation
The Viton seals enable reliable operation in ambient temperatures up to 150°C, making it suitable for pressing, clamping, or ejecting parts near ovens, autoclaves, or heated platens.
Material Handling & Sorting
With 1374 N of force at 0.7 MPa, it provides ample power for diverting packages, actuating gates, or pushing products off a conveyor line in a medium-duty cycle.
Assembly & Joining Fixtures
The 350 mm stroke and 20 mm rod are well-suited for assembly stations requiring a long reach, such as inserting bushings, applying adhesives, or operating a welding mask slide.
Is the Airtac SC50 Standard Cylinder SC50X350H the Right Cylinder?
For applications needing more force, stepping up to the SC63 bore provides 1559 N of push at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the SC40 bore offers 628 N at the same pressure. At a 350 mm stroke, ensure the 20 mm rod is adequately supported against side loads; an external linear guide is recommended if the load is not purely axial to prevent rod bending and premature bearing wear. When replacing an existing unit, match the 50 mm bore, 350 mm stroke, PT port thread, and verify the magnet and mounting requirements—this basic-body model has no built-in magnet or brackets.
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 SC50X350H FAQ
At 0.5 MPa the push force is 982 N and pull force is 825 N. At 0.7 MPa push force increases to 1374 N. The maximum safe operating push force at 0.9 MPa is 1767 N. The theoretical force at 1.0 MPa is 200 kgf, but operating above 1.0 MPa is not permitted.
No. The SC50X350H is a standard double-acting cylinder and will drift or drop if air pressure is lost or the directional valve is centered. The adjustable air cushion only decelerates the piston at the end of stroke; it does not lock or hold the load. For position holding, add an external pilot-operated check valve or a mechanical rod lock.
