The AirTAC SC50 Standard Cylinder SC50X620SN is a genuine double-acting standard air cylinder with a Ø50mm bore and 620mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X620SN is a double-acting pneumatic cylinder with a 50 mm bore and a 620 mm stroke, built on the compact AirTAC SC tie-rod platform. It produces a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, driven by a 20 mm diameter piston rod with an M16x1.5 male thread.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, and is fitted with NBR (nitrile) seals (-N suffix) for reliable performance within the standard -20 to +70 °C temperature range. The PT1/4 port and adjustable air cushion at both ends provide controlled deceleration for the 620 mm stroke.

The 620 mm stroke and 982 N push force at 0.5 MPa reliably actuate diverter gates on wide conveyor lines, with the built-in magnet enabling easy end-of-stroke position sensing.
Clamps large workpieces in welding cells, where the NBR seals resist standard shop air contaminants and the adjustable cushion smoothly decelerates the 620 mm stroke.
Positions a pallet dispenser or layer-forming carriage across a 620 mm travel, with sensor feedback from the -S magnet confirming safe retraction before the next cycle.
For applications needing more force, stepping up to the 63 mm bore SC63 series increases push force to 1559 N at 0.5 MPa. If a shorter, more rigid assembly is preferred, the 40 mm bore SC40 series offers 628 N at 0.5 MPa but with a 16 mm rod. This 620 mm stroke is within the 1200 mm maximum standard stroke for the 50 mm bore.
At this stroke length, the 20 mm rod is susceptible to bending under side loads. An external linear guide or a guided cylinder is strongly recommended to protect the rod bearings and ensure long service life. For direct replacement, match the 50 mm bore, 620 mm stroke, PT1/4 port, NBR seals, and the integrated magnet for sensor compatibility.
Quick checklist
At 0.5 MPa, the cylinder provides 982 N pushing and 825 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force reaches 1767 N. The theoretical maximum force at 1.0 MPa is 200 kgf.
No. The SC50X620SN 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 will drift. A pilot-operated check valve or external rod lock is required for static load holding.
