The AirTAC SC50 Standard Cylinder SC50X90N is a genuine double-acting standard air cylinder with a Ø50mm bore and 90mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X90N is a double-acting tie-rod cylinder from the AirTAC SC series, configured with a 50 mm bore and a 90 mm stroke. It produces a push force of 982 N at 0.5 MPa, rising to 1767 N at the maximum operating pressure of 0.9 MPa, making it a capable mid-range actuator for general industrial tasks.
This model is fitted with NBR (nitrile) seals, which offer good resistance to oils and greases within the standard operating temperature range of -20 to +70 °C. The piston rod has a diameter of 20 mm with an M16x1.5 male thread, and the cylinder features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.

Ideal for a 90 mm linear transfer on a conveyor line, pushing components onto a weigh station or diverter gate with a controlled 982 N force at standard plant pressure.
Provides a strong, repeatable clamping action for woodworking or light metal fabrication jigs. The NBR seals offer good durability in environments with oil mist.
Suited for actuating chutes, gates, or sorting mechanisms on farming equipment where NBR seals provide reliable performance in contact with greases and oils.
Select this 50 mm bore cylinder when the 40 mm bore's 628 N push force at 0.5 MPa is insufficient. If your application demands more than 1767 N at 0.9 MPa, step up to the 63 mm bore, which provides 2805 N. For a 90 mm stroke, side loading is typically not a primary concern, but always ensure the load is guided and aligned with the rod axis to prevent premature seal and bearing wear.
To replace an existing SC50X90N, match five key points: the 50 mm bore, 90 mm stroke, PT1/4 port thread, NBR seal material, and the basic (no bracket) mounting configuration. This cylinder is a direct replacement for another AirTAC SC50 tie-rod unit with the same specifications.
Quick checklist
At 0.5 MPa, the cylinder delivers 982 N of push force and 825 N of pull force. 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.
No. The AirTAC SC series is a tie-rod cylinder, not an ISO 15552 profile cylinder. Its body length is shorter, so ISO 15552 mounting accessories will not fit. You must use AirTAC SC-specific mounts, such as the F-SC50LB foot mount or F-SC50FA front flange.
