The AirTAC SC50 Standard Cylinder SC50X650SN 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 SC50X650SN is a double-acting pneumatic cylinder delivering 982 N push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa. With a 50 mm bore and a 650 mm stroke, it uses a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion (21 mm length) decelerates the piston smoothly at both ends of the stroke.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors on the barrel, eliminating the need for external switch rails. The NBR seal option (-N suffix) provides reliable sealing for standard industrial air supplies. The body length A is 150 mm, giving an extended length of approximately 800 mm.

The 1767 N thrust at 0.9 MPa suits press-fit and staking operations in automated assembly cells. The built-in magnet enables end-of-stroke confirmation via solid-state sensors.
With a 650 mm stroke, this cylinder can push product across a wide conveyor lane. NBR seals handle the dusty conditions common in packaging and logistics environments.
The 982 N force at standard shop air (0.5 MPa) is sufficient to slide filled cartons onto a pallet. The magnetic piston allows sensor-based stroke verification for reliable automation sequences.
For applications requiring more force, stepping up to the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa—a 59% increase. If space or weight is a concern, the 40 mm bore SC40 delivers 628 N at 0.5 MPa. At 650 mm stroke, the 20 mm rod is relatively long; side loads or off-centre mounting can cause rod deflection and premature bearing wear. Use an external linear guide or a guided cylinder unit if the load is not perfectly axial.
To replace an existing SC50X650SN, match five points: 50 mm bore, 650 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the NBR seal material. The SC series is a tie-rod cylinder with a shorter overall length than ISO 15552 profiles, so dimensional interchangeability is limited to other AirTAC SC50 tie-rod cylinders.
Quick checklist
At 0.5 MPa the push force is 982 N and pull force is 825 N. At 0.7 MPa push reaches 1374 N, and at the maximum operating pressure of 0.9 MPa it delivers 1767 N push. The theoretical maximum at 1.0 MPa is 200 kgf. Pull force is always lower due to the rod area.
Yes. The -S suffix in SC50X650SN indicates a built-in magnet on the piston. AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rods to detect piston position without additional brackets.
