The AirTAC SC50 Standard Cylinder SC50X620S 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 AirTAC SC50X620S is a double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa and up to 1767 N at 0.9 MPa. With a 50 mm bore, 20 mm rod, and a non-standard 620 mm stroke, it suits applications needing extended reach beyond the standard 500 mm range. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for piston position feedback.
This model features a PT1/4 port, M16x1.5 rod thread, and a 21 mm adjustable air cushion to decelerate the piston smoothly at stroke end. The body length A is 150 mm, giving a total extended length of approximately 770 mm. For strokes over 300 mm, ensure the rod is guided externally if side loads are present to prevent bending or bearing wear.

The 620 mm stroke pushes or pulls parts across wide conveyor gaps or between distant stations, with magnetic sensors confirming end-of-travel.
Applies 1767 N of clamping force at 0.9 MPa over a long stroke to secure large workpieces, with sensor feedback ensuring the clamp is fully engaged.
Operates tall diverter gates or flaps in sorting systems, using the built-in magnet for position verification at both ends of the 620 mm stroke.
Choose the SC50X620S when your application requires a 50 mm bore with a 620 mm reach and sensor-ready position sensing. If 982 N at 0.5 MPa is insufficient, stepping up to the 63 mm bore (SC63) provides 1559 N at the same pressure. For a shorter standard stroke, the SC50X500 offers a direct alternative within the standard range.
This non-standard stroke cylinder must be matched on five points for replacement: 50 mm bore, 620 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic (no bracket) mounting. The long 620 mm stroke requires careful alignment; use an external guide or rod support to protect the rod bearing from bending moments under side load.
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 reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Match five key specifications: 50 mm bore, 620 mm stroke, PT1/4 port thread, built-in magnet for sensors (-S suffix), and basic mounting. This is a non-standard stroke, so confirm the overall extended length of ~770 mm fits your machine. Ensure the rod is externally guided if side loads exist.
