The AirTAC SC50 Standard Cylinder SC50X75SLB is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75SLB is a double-acting pneumatic cylinder with a 50 mm bore and 75 mm stroke, delivering a push force of 982 N at 0.5 MPa (up to 1767 N at 0.9 MPa). This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and comes with an LB foot mount for stable axial surface installation.
Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-range loads. The cylinder body length A is 150 mm, giving a compact extended length of 225 mm. Operating on filtered air from 0.15 to 1.0 MPa, it suits standard industrial temperatures from -20 to +70 °C with its TPU seals.

The 75 mm stroke and 982 N push force at 0.5 MPa are ideal for actuating part stops or sorting gates on light-to-medium duty conveyors, with the LB mount providing a rigid, fixed base.
Use the SC50X75SLB for pneumatic clamping fixtures. The built-in magnet allows sensors to confirm clamp position, ensuring safe machine cycles in assembly or machining operations.
With up to 1767 N of force at 0.9 MPa, this cylinder can power small pressing or labeling stations in packaging lines, where the foot mount simplifies integration onto flat machine beds.
Choose the SC50 bore when your application needs around 982 N of push force at 0.5 MPa. If you require more force, step up to the SC63 bore, which provides 1559 N at the same pressure. For lighter, faster cycles, the SC40 bore offers 628 N. This 75 mm stroke is within the standard range for the 50 mm bore (max 1200 mm).
For a direct replacement, match five points: 50 mm bore, 75 mm stroke, PT port thread, LB foot mounting (F-SC50LB), and the built-in magnet (-S). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 1374 N. The pull force on the retract stroke is 825 N at 0.5 MPa. Maximum operating force at 0.9 MPa is 1767 N.
Yes. The -S suffix indicates a built-in magnet in the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor groove to detect piston position.
