The AirTAC SC50 Standard Cylinder SC50X55S is a genuine double-acting standard air cylinder with a Ø50mm bore and 55mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X55S is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 50 mm bore with a 55 mm stroke. At 0.5 MPa it generates 982 N of push force and 825 N pull force, driven by a 20 mm diameter piston rod, making it a strong mid-range actuator for short linear movements.
This model includes the factory-fitted -S magnet option, so CMSG/DMSG/EMSG reed and solid-state sensors can be clamped directly onto the barrel for non-contact position sensing. The cylinder body length A is 150 mm, giving a total extended length of approximately 205 mm, and it features adjustable pneumatic cushioning over a 21 mm stroke-end zone to decelerate the piston smoothly.

The 55 mm stroke and 982 N push force are ideal for compact part-stop gates on light-duty conveyors, where the built-in magnet confirms the gate is fully retracted.
With the -S magnet and CMSG sensors, this cylinder suits automated clamping fixtures that require end-of-stroke confirmation to interlock with a machine cycle.
Actuates small diverter flaps in chutes or packaging lines. The 21 mm adjustable cushion protects the flap mechanism from impact at the end of travel.
For applications needing slightly more force, stepping up to the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If a shorter overall length is required, the 40 mm bore SC40 delivers 628 N at 0.5 MPa. Always match replacement cylinders on five points: 50 mm bore, 55 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the basic (no bracket) mounting configuration.
Although the 55 mm stroke is short, ensure side loads are minimized or handled by external guides, as the 20 mm rod and front bearing are designed primarily for axial thrust.
Quick checklist
At the standard operating pressure of 0.5 MPa, the push force is 982 N and the pull force is 825 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N.
Yes. The -S suffix means this cylinder has a built-in magnet. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position.
