The AirTAC SC50 Standard Cylinder SC50X500LB is a genuine double-acting standard air cylinder with a Ø50mm bore and 500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X500LB is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at the maximum operating pressure of 0.9 MPa). With a 50 mm bore and a 500 mm stroke, it features a 20 mm diameter piston rod and an adjustable air cushion of 21 mm to decelerate end-of-stroke impact.
This model is equipped with an LB foot mount (F-SC50LB) for secure surface mounting on the barrel. The standard PT1/4 ports and TPU seals with a -20 to +70 C operating range make it a reliable workhorse for general industrial automation tasks.

The 500 mm stroke and 982 N force at 0.5 MPa are ideal for raising and lowering a stop gate on a conveyor line, reliably halting pallets or totes.
Delivers consistent clamping pressure for woodworking or metal fabrication jigs. The LB foot mount provides a stable, bolted-down base for repetitive operations.
Use the long 500 mm reach to push cartons or products off a main line onto a sorting lane, with the adjustable cushion ensuring a smooth, low-impact transfer.
Choose the SC50X500LB when your application requires a clamping or pressing force around 980 N at standard shop air. If you need more force, stepping up to the SC63 bore provides 1559 N at 0.5 MPa. For strokes of 500 mm, ensure the load is guided externally to prevent side-load bending on the 20 mm rod, which can damage the rod bearing and seals. This cylinder is a direct replacement for any AirTAC SC50 tie-rod unit with the same bore, 500 mm stroke, PT ports, and LB foot mount.
Quick checklist
At 0.7 MPa (7 bar), the theoretical push force is 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa, due to the area reduction from the 20 mm piston rod.
It is a direct dimensional match for any AirTAC SC50 cylinder with a 500 mm stroke and PT1/4 ports. The LB foot mount is integral to this model code; to match a different mounting style, you would need the corresponding suffix (e.g., FA for front flange, TC for center trunnion).
