The AirTAC SC50 Standard Cylinder SC50X84 is a genuine double-acting standard air cylinder with a Ø50mm bore and 84mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X84 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With an 84 mm stroke and a 20 mm diameter piston rod, this model is well-suited for medium-duty clamping, pressing, and ejector tasks where a compact footprint is required.
Its tie-rod construction provides a body length of 150 mm, making it shorter than a comparable ISO 15552 cylinder. The cylinder features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. This model is configured with the standard TPU seals for a temperature range of -20 to +70 °C and PT threaded ports.

Provides the 982 N push force needed to reliably stop or divert medium-weight packages and totes on conveyor lines, with the 84 mm stroke offering a precise actuation distance.
Ideal for small benchtop pressing or staking fixtures, where the 1767 N maximum force at 0.9 MPa is sufficient for inserting bearings or fasteners with a controlled 84 mm stroke.
Used to eject parts from injection molds or stamping dies, the adjustable cushion protects the tooling by softly decelerating the 20 mm rod and payload at the end of the 84 mm stroke.
Select the SC50X84 when your application needs approximately 982 N of force at standard plant air pressure. If you require more force, stepping up to the 63 mm bore provides 1559 N at the same 0.5 MPa pressure. For lower force requirements, the 40 mm bore offers 628 N. Always ensure the rod is guided externally if the 84 mm stroke is combined with significant side loads, as the 20 mm rod is designed primarily for axial thrust.
When replacing an existing cylinder, match five key points: bore (50 mm), stroke (84 mm), port thread (PT 1/4), mounting style (basic, no bracket), and the presence of a magnet (this model has none). This ensures a direct dimensional and functional swap with another AirTAC SC50 cylinder.
Quick checklist
The theoretical push force is 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. 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.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 profile cylinder. For a direct replacement, you must match another AirTAC SC50 tie-rod cylinder with the same 84 mm stroke and PT port thread.
