The AirTAC Airtac SC50 Standard Cylinder SC50X950S is a genuine double-acting standard air cylinder with a Ø50mm bore and 950mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X950S is a double-acting tie-rod cylinder with a 50 mm bore and a 950 mm stroke, delivering 982 N of push force and 825 N of pull force at 0.5 MPa. It features a 20 mm diameter piston rod with M16x1.5 male threads, PT1/4 ports, and a 21 mm adjustable air cushion at each end to decelerate the piston smoothly. The built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position sensing.
At 0.9 MPa maximum operating pressure, this cylinder generates 1767 N of thrust, making it suitable for medium-force clamping, pressing, and transfer tasks. With a body length A of 150 mm, the total extended length is approximately 1100 mm. For a 950 mm stroke, ensure the rod is guided externally or the load is purely axial to prevent bending stress on the 20 mm rod. This model uses standard TPU seals and PT threads, operating reliably from -20 to +70 °C.

Moves components 950 mm between conveyor lines or workstations. The built-in magnet enables mid-stroke position confirmation via DMSG sensors.
Applies up to 1767 N of clamping pressure at 0.9 MPa for woodworking or assembly fixtures, with adjustable cushioning to reduce impact at the end of the 950 mm stroke.
Pushes totes or cartons off a gravity roller lane. The long 950 mm stroke reaches across wide conveyor beds, and the magnetic piston confirms full extension and retraction.
Choose the SC50 bore when your application needs between 825 N and 1767 N of force. If you require more force, step up to the SC63 bore, which provides 1559 N push at 0.5 MPa. For a lighter, more compact solution, the SC40 bore delivers 628 N push at 0.5 MPa. The 950 mm stroke is within the 1200 mm maximum standard stroke for bore 50.
For strokes of this length, side loading is a critical consideration. The 20 mm rod can bend under off-axis loads when fully extended. Use an external linear guide or rod support to absorb side forces, or consider a guided cylinder assembly. To replace an existing SC50X950S, match the 50 mm bore, 950 mm stroke, PT1/4 ports, built-in magnet (-S), and basic mounting configuration exactly.
Quick checklist
At 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, the push force increases to 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The -S suffix indicates a built-in magnet inside the piston, which is required for CMSG, DMSG, or EMSG sensors to detect position. This model (SC50X950S) includes the magnet, so sensors can be clamped directly onto the tie-rod barrel.
