The AirTAC Airtac SC50 Standard Cylinder SC50X525S is a genuine double-acting standard air cylinder with a Ø50mm bore and 525mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X525S is a double-acting tie-rod cylinder with a 50 mm bore and a non-standard 525 mm stroke, delivering 1374 N of push force at 0.7 MPa. Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable end-of-stroke deceleration for medium-duty linear tasks.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors on the barrel for contactless position feedback. The TPU seal and PT1/4 port thread suit standard compressed air systems operating from -20 to +70 °C.

Actuates a diverter gate on a conveyor line, using the built-in magnet and sensors to confirm open/closed position before product passes.
Provides 1374 N of clamping force at 0.7 MPa to hold workpieces during light machining or assembly, with sensor feedback ensuring the clamp is engaged.
Extends a stop pin at the end of a gravity roller lane. The long 525 mm stroke allows the pin to retract fully below the roller surface.
The SC50 provides 982 N of push at 0.5 MPa. If your load requires more force, stepping up to the 63 mm bore (1559 N at 0.5 MPa) may be a better match; for lighter loads, the 40 mm bore (628 N) saves space. At 525 mm stroke, the rod is extended significantly—ensure side loads are minimal or use an external guide to protect the rod bearing from bending moments.
For a drop-in replacement, match five points: 50 mm bore, 525 mm stroke, PT1/4 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting configuration.
Quick checklist
At 0.5 MPa it delivers 982 N push and 825 N pull. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N.
Yes. The -S suffix indicates a built-in magnet, so you can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel for end-of-stroke or mid-stroke position detection.
