The AirTAC SC50 Standard Cylinder SC50X650SH 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 AirTAC SC50X650SH is a double-acting single-rod pneumatic cylinder with a 50 mm bore and 650 mm stroke, delivering 982 N of push force at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. The built-in magnet (-S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback without external brackets.
This model is equipped with Viton (FKM) seals (-H suffix), shifting the operating temperature range to 0 to +150 °C for reliable performance in hot or chemically aggressive environments where standard TPU seals would degrade. The 650 mm stroke is within the 1200 mm maximum standard stroke for bore 50, and the cylinder features a 20 mm diameter piston rod with M16x1.5 male threads, PT1/4 ports, and an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.

With Viton seals rated for 0 to 150 °C, this cylinder is suited for actuator duties near ovens, autoclaves, or heated presses where standard seals would fail.
The 650 mm stroke and 1767 N push force at 0.9 MPa efficiently transfer components between conveyor lines or workstations, with magnetic sensors confirming full extension and retraction.
The built-in magnet enables direct barrel-mounted sensors to verify clamp position in automated welding or assembly fixtures, ensuring cycle safety and repeatability.
For applications requiring higher force, stepping up to the 63 mm bore SC63 series provides 1559 N at 0.5 MPa. If a shorter, more compact cylinder suits the machine layout, the 40 mm bore SC40 series delivers 628 N at the same pressure. At a 650 mm stroke, ensure the rod is not subjected to significant side loading; if the load is not guided externally, consider adding an external linear guide or switching to a guided cylinder to prevent rod bearing wear and bending.
To ensure a direct replacement, match five key points: 50 mm bore, 650 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This SC tie-rod cylinder is shorter than an ISO 15552 profile and is not dimensionally interchangeable with that standard.
Quick checklist
At 0.5 MPa, the cylinder provides 982 N pushing and 825 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X650SH is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is lost or the directional valve is centered, the piston can drift. For load holding without live pressure, an external pilot-operated check valve or a mechanical rod lock is required.
