About the Airtac SC50 Standard Cylinder SC50X400H
The SC50X400H is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa, scaling to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 400 mm stroke, this tie-rod actuator uses a 20 mm diameter piston rod and features an adjustable air cushion length of 21 mm to decelerate end-of-stroke impact.
This model is equipped with Viton (FKM) seals, designated by the 'H' suffix, shifting the operating temperature range to 0 to +150 °C for reliable performance in high-heat environments. The standard PT1/4 port threads and M16x1.5 rod thread ensure straightforward pneumatic connections. For position sensing, note that this specific code lacks a built-in magnet.

Where the Airtac SC50 Standard Cylinder SC50X400H Is Used
High-Temperature Process Automation
Viton seals enable reliable actuation of valves, dampers, and gates in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150 °C.
Hot Press and Molding Clamping
Delivers a consistent 1767 N clamping force at 0.9 MPa for heated platen presses, composite curing molds, and thermal bonding fixtures.
Material Handling in Heat Zones
Operates push-pull diverters and transfer stations on conveyor lines passing through drying tunnels or heat-shrink chambers without seal degradation.
Is the Airtac SC50 Standard Cylinder SC50X400H the Right Cylinder?
For higher force requirements, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact actuator is sufficient, the 40 mm bore delivers 628 N. At a 400 mm stroke, ensure the rod is protected from side loads; an external guide or linear rail is recommended to prevent rod bending and premature bearing wear. When replacing, match the 50 mm bore, 400 mm stroke, PT1/4 port thread, basic mounting, and Viton seal material to guarantee an exact functional interchange.
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 SC50X400H FAQ
At 0.7 MPa (roughly 100 psi), the push force is 1374 N. The theoretical maximum push force at 1.0 MPa is 200 kgf, though the operating limit is 1.0 MPa.
No. The SC50X400H is a standard double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, you must add an external rod brake or a pilot-operated check valve.
