The AirTAC SC50 Standard Cylinder SC50X800S is a genuine double-acting standard air cylinder with a Ø50mm bore and 800mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X800S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa). Its 20 mm diameter piston rod and 800 mm stroke suit medium-force linear transfer tasks where mid-stroke sensing is required.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position detection. The adjustable air cushion at each end decelerates the piston smoothly over a 21 mm cushion length, protecting end caps during high-cycle operation.

The 800 mm stroke and sensor-ready barrel allow precise, adjustable end-of-stroke sensing for stopping or diverting packages on wide conveyor lines.
Moves components between distant stations in automated assembly. The built-in magnet lets you confirm full extension and retraction at each cycle.
Provides the 982 N push needed to slide a single pallet from a stack onto a roller bed, with sensor feedback ensuring complete pallet ejection.
For a 50 mm bore at 0.5 MPa, expect 982 N push and 825 N pull. If your load exceeds this, stepping up to a 63 mm bore provides 1559 N push at the same pressure. For strokes of 800 mm, the 20 mm rod is relatively slender—avoid direct side loads. If the rod must guide or support the load externally, pair the cylinder with an external linear guide or switch to a guided cylinder to prevent rod bending and premature bearing wear.
When replacing this unit, match five points: 50 mm bore, 800 mm stroke, PT port thread, the built-in magnet for sensors, and the basic (no bracket) mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder produces 982 N extending and 825 N retracting. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force at 1.0 MPa is 200 kgf.
Yes. The -S suffix indicates a built-in magnet in the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel to detect piston position without external brackets.
