The AirTAC Airtac SC50 Standard Cylinder SC50X950 is a genuine double-acting standard air cylinder with a Ø50mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X950 is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa, scaling up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 950 mm stroke, this model uses a 20 mm diameter piston rod and features an adjustable pneumatic cushion (21 mm length) to decelerate the load smoothly at each end of travel.
This cylinder's body length A is 150 mm, giving a total extended length of approximately 1100 mm. As a genuine AirTAC SC series unit, it is built with a PT1/4 port and standard TPU seals rated for -20 to +70 °C, making it a robust choice for general industrial automation tasks requiring a long linear reach.

Moves components across a 950 mm span between conveyor lines or workstations, using its 982 N force at 0.5 MPa to handle medium-weight transfer arms.
Extends a dispensing head along a 950 mm linear path for applying adhesives or sealants, with the adjustable cushion preventing fluid splash at stroke end.
Provides a 950 mm vertical lift for pallet dispensers or stackers, where the 1767 N maximum force at 0.9 MPa handles substantial vertical loads with controlled cushioning.
For a 50 mm bore at 0.5 MPa, the SC50X950 provides 982 N of push force. If your load requires more force, stepping up to the SC63 bore delivers 1559 N at the same pressure. For lighter, faster applications, the SC40 bore offers 628 N. This 950 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
At this long stroke, the 20 mm rod is susceptible to bending under side loads. Always guide the load externally with a rail system or use a guided cylinder variant to prevent rod bearing damage and ensure reliable operation. For replacement, match the bore, stroke, PT1/4 port thread, basic mounting configuration, and the absence of a magnet sensor option.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
For a 950 mm stroke, the 20 mm rod must be protected from side loads. Use an external linear guide rail to support the tooling plate, or consider an AirTAC guided cylinder series. The cylinder's rod bearing is designed for axial loads, not bending moments from unsupported side forces.
