The AirTAC SC50 Standard Cylinder SC50X550SLB is a genuine double-acting standard air cylinder with a Ø50mm bore and 550mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X550SLB is a double-acting single-rod pneumatic cylinder delivering 1374 N of push force at 0.7 MPa (1767 N at the 0.9 MPa maximum operating pressure). With a 50 mm bore and a 550 mm stroke, it is built on a robust tie-rod body that is shorter than an equivalent ISO 15552 cylinder, saving space in machine frames.
This model incorporates a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and comes configured with LB axial foot mounts (F-SC50LB) for secure surface installation. The 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration, while the PT1/4 port thread ensures straightforward pneumatic connection.

Operates diverter gates on conveyor lines where the 550 mm stroke provides ample travel, and the magnetic piston confirms gate position via barrel-mounted sensors.
Powers clamping or pressing fixtures in assembly cells. The LB foot mount secures the cylinder to a baseplate, while the 1374 N force at 0.7 MPa holds parts firmly during joining.
Drives product pushers in case-packing machinery. The adjustable cushion absorbs impact at the end of the 550 mm stroke, protecting the carton and the cylinder seals.
Select the SC50X550SLB when your application requires a mid-range force actuator with full stroke-position sensing. The 50 mm bore provides 982 N of push force at 0.5 MPa; if you need more force, step up to the 63 mm bore (1559 N at 0.5 MPa), or down to the 40 mm bore (628 N at 0.5 MPa) for lighter, faster cycles.
For this 550 mm stroke, ensure the load is guided externally if side forces are present—a long, unsupported 20 mm rod can bend under lateral load. When replacing an existing cylinder, match five points: 50 mm bore, 550 mm stroke, PT1/4 port thread, LB foot mounting (F-SC50LB), and the built-in magnet for sensor compatibility.
Quick checklist
At 0.7 MPa (approximately 100 psi), the push force is 1374 N. The theoretical maximum push force at the 1.0 MPa limit is 200 kgf. At the minimum operating pressure of 0.15 MPa, push force is approximately 295 N.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without any additional brackets.
