The AirTAC SC50 Standard Cylinder SC50X650S is a genuine double-acting standard air cylinder with a Ø50mm bore and 650mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X650S is a double-acting pneumatic cylinder delivering 982 N of push force at 0.5 MPa (1374 N at 0.7 MPa), built around a 50 mm bore and a 20 mm diameter piston rod. The 650 mm stroke is within the standard range for this bore, and the adjustable air cushion (21 mm length) decelerates the piston smoothly at each end of travel.
This model includes the factory-installed -S magnet embedded in the piston, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A is 150 mm, giving a total extended length of approximately 800 mm.

The 650 mm stroke and magnetic piston sensing make this cylinder ideal for long-reach part stops or lane diverters on packaging conveyors, confirming position at both ends.
Provides consistent clamping force for medium-duty welding or assembly fixtures, with sensor feedback ensuring the clamp is fully open or closed before the next cycle.
Operates slide gates on hoppers or chutes with a 650 mm opening stroke; the magnetic sensors verify the gate position to prevent material bridging or spillage.
Choose the SC50 when your application needs roughly 1000–1400 N of force at typical shop air pressures; if you need more, the SC63 delivers 1559 N at 0.5 MPa, and if you need less, the SC40 provides 628 N. For this 650 mm stroke, ensure the load is guided and the rod is not subjected to significant side forces—long, unsupported rods can bend under lateral load. When replacing an existing cylinder, match five points: 50 mm bore, 650 mm stroke, PT1/4 ports, the built-in magnet (-S), and any mounting accessory.
Quick checklist
At 0.5 MPa the cylinder pushes with 982 N and pulls with 825 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix means this cylinder has a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the tie-rod barrel to detect piston position without any modification.
