The AirTAC SC50 Standard Cylinder SC50X80H is a genuine double-acting standard air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X80H is a double-acting tie-rod cylinder engineered for high-temperature environments, delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 80 mm stroke and 20 mm diameter piston rod are well-suited for compact actuation tasks where ambient heat would degrade standard seals.
This model features Viton (FKM) seals, shifting the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C. The cylinder body length is 150 mm, and it includes an adjustable pneumatic cushion (21 mm) to decelerate the piston quietly at end-of-stroke. Ports are PT1/4 with an M16x1.5 rod thread.

Actuating gates, dampers, or diverters inside industrial ovens, kilns, or autoclave loading systems where ambient temperatures exceed 70°C.
Providing consistent clamping or ejection force in heated platen presses, thermoforming machines, or rubber molding equipment.
Simulating mechanical motion during hot-engine or exhaust-system testing, where the cylinder is exposed to radiated heat.
Select the SC50X80H when your application requires reliable pneumatic actuation in hot surroundings, such as near ovens, furnaces, or autoclaves, where standard TPU seals would fail. If you need more force at the same pressure, stepping up to the 63 mm bore provides 1559 N of push at 0.5 MPa.
For replacement, ensure a direct dimensional match: 50 mm bore, 80 mm stroke, PT1/4 ports, and Viton seals. This is a basic mount cylinder; if your original had a foot, flange, or trunnion, you must order the corresponding F-SC50 accessory separately. Note that this code does not include a magnet; sensor mounting requires the -S suffix.
Quick checklist
At the standard maximum operating pressure of 0.9 MPa, the theoretical push force is 1767 N. At a typical factory air pressure of 0.5 MPa, it generates 982 N pushing and 825 N pulling. The maximum theoretical force at 1.0 MPa is 200 kgf.
Yes, the SC50X80H is dimensionally identical to the standard TPU-seal model and can be used as a direct replacement in normal temperatures. The Viton seals provide an extended temperature ceiling without changing the mounting envelope or port locations.
