The AirTAC SC50 Standard Cylinder SC50X540S is a genuine double-acting standard air cylinder with a Ø50mm bore and 540mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X540S is a double-acting single-rod tie-rod cylinder delivering a push force of 982 N at 0.5 MPa and up to 1767 N at the maximum operating pressure of 0.9 MPa. With a 20 mm diameter piston rod and a 540 mm stroke, this model extends to a total length of approximately 690 mm, making it suitable for long linear movements in material handling and packaging machinery.
This cylinder features a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for non-contact position sensing. The stroke of 540 mm exceeds the standard maximum of 1200 mm for 50 mm bore, so this is a non-standard made-to-order configuration. The adjustable pneumatic cushion at both ends, with a cushion length of 21 mm, decelerates the piston smoothly to reduce end-of-stroke impact.

The 540 mm stroke and 1767 N push force at 0.9 MPa reliably actuates diverter gates on packaging and sorting conveyors, with the built-in magnet providing end-of-travel confirmation via barrel-mounted sensors.
Ideal for pushing components along a 540 mm linear path in assembly fixtures. The adjustable cushion decelerates the 20 mm rod smoothly, protecting delicate parts from impact damage.
Deploys a stop or stripper plate across a wide roller conveyor. The -S magnet option allows easy integration of CMSG/DMSG sensors to signal the raised and lowered positions to the line controller.
Select the SC50X540S when your application requires a 50 mm bore cylinder with a 540 mm stroke and integrated position feedback. For higher force requirements, stepping up to a 63 mm bore provides 1559 N of push force at 0.5 MPa. For a shorter, standard stroke, consider the SC50X500 which is typically available from stock.
At a stroke of 540 mm, the 20 mm rod is susceptible to bending under side loads. An external linear guide or a guided cylinder configuration is strongly recommended to protect the rod bearing and ensure reliable operation. When replacing an existing cylinder, match five key points: 50 mm bore, 540 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting style.
Quick checklist
At the standard operating pressure of 0.7 MPa, the push force is 1374 N. The maximum push force at 0.9 MPa is 1767 N. The pull force on the retract stroke is lower due to the rod area, delivering 825 N at 0.5 MPa.
No, the maximum standard stroke for a 50 mm bore SC cylinder is 1200 mm. A 540 mm stroke is a non-standard, made-to-order length. It requires the same 5-point match for replacement: 50 mm bore, 540 mm stroke, PT1/4 port, basic mounting, and the built-in magnet.
