The AirTAC SC50 Standard Cylinder SC50X800TC is a genuine double-acting standard air cylinder with a Ø50mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X800TC 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 an 800 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-force linear transfer and lifting tasks that require a long, smooth travel.
This configuration includes a centre trunnion (TC) mount, supplied with the TCM1 bracket (F-SC50TC), allowing the cylinder to pivot during operation to accommodate angular motion. The body length A is 150 mm, and the adjustable air cushion at each end is 21 mm, effectively decelerating the piston to reduce end-of-stroke impact. Operating on filtered air from -20 to +70 °C, it uses standard PT ports and TPU seals.

Moves components 800 mm between conveyor lines or assembly stations. The centre trunnion mount allows the cylinder to swing, accommodating slight misalignments in the transfer path.
Raises and lowers access panels or guards on large machine tools. The 1767 N push force at 0.9 MPa handles substantial panel weights, while the air cushion ensures a soft stop.
Actuates a diverter gate on a chute or hopper in a material handling system. The trunnion pivot is ideal for the arcing motion of a gate, and the long stroke provides full gate clearance.
For applications needing more force, stepping up to the 63 mm bore provides 1559 N at 0.5 MPa. For a lighter, more compact solution, the 40 mm bore offers 628 N. When replacing this cylinder, ensure a 5-point match: 50 mm bore, 800 mm stroke, PT port thread, centre trunnion (TC) mounting, and no magnet.
At an 800 mm stroke, the extended rod is susceptible to bending under side loads. It is critical to guide the load externally with a linear rail or rod guide, or to select a guided cylinder, to prevent rod bearing damage and ensure reliable operation.
Quick checklist
At 0.5 MPa (5 bar), the theoretical push force is 982 N. At the maximum operating pressure of 0.9 MPa, the force increases to 1767 N. The pull force on the retract stroke is 825 N at 0.5 MPa due to the rod area.
For any stroke over 300 mm, side loads are a primary concern. The rod must be externally guided by a linear rail or rod guide attached to the tooling plate. Alternatively, consider a guided cylinder or rodless actuator if the side load cannot be eliminated.
