The AirTAC SC50 Standard Cylinder SC50X345STC is a genuine double-acting standard air cylinder with a Ø50mm bore and 345mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X345STC is a double-acting single-rod pneumatic cylinder with a 50 mm bore and a 345 mm stroke, pre-configured with a built-in magnet and a centre trunnion mounting. It generates a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it a robust actuator for medium-duty automation tasks.
This model features a 20 mm diameter piston rod with an M16x1.5 male thread and PT1/4 port connections. The adjustable air cushion at both ends of the 21 mm stroke provides smooth deceleration, protecting the end caps during high-cycle operations. The body length (dimension A) is 150 mm, resulting in a total extended length of approximately 495 mm.

The centre trunnion mount allows this cylinder to pivot, making it perfect for actuating diverter gates on conveyor systems. The 345 mm stroke provides ample travel to redirect packages or components between lanes.
With 982 N of force at 0.5 MPa and sensor-ready position feedback via the built-in magnet, this cylinder reliably clamps parts in automated welding cells, confirming clamp status before the cycle starts.
The 1767 N of force at 0.9 MPa can easily operate sliding doors on aggregate or grain hoppers. The adjustable cushioning handles the high inertial loads when the door reaches the end of its 345 mm travel.
For applications requiring slightly less force, consider stepping down to the 40 mm bore SC40 series, which provides 628 N of push force at 0.5 MPa. If higher force is needed, the 63 mm bore SC63 series offers 1559 N at the same pressure. This SC50X345STC model is configured with a centre trunnion (TC) mount, ideal for applications where the cylinder body needs to pivot. The built-in magnet (-S suffix) allows for direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position feedback. For a successful replacement, match these five points: 50 mm bore, 345 mm stroke, PT port thread, centre trunnion (TC) mounting with TCM1 bracket, and the integrated magnet for sensors.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 1374 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 'S' indicates a built-in magnet on the piston, allowing you to mount CMSG, DMSG, or EMSG sensors directly on the cylinder barrel for position sensing. The 'TC' stands for centre trunnion mount, which includes the TCM1 trunnion bracket (order code F-SC50TC) and allows the cylinder body to pivot during operation.
