The AirTAC Airtac SC40 Standard Cylinder SC40X63S is a genuine double-acting standard air cylinder with a Ø40mm bore and 63mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X63S is a genuine AirTAC double-acting tie-rod cylinder with a 40 mm bore and 63 mm stroke, factory-equipped with a built-in magnet. The magnet lets you clamp CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the barrel for reliable end-of-stroke or mid-stroke position sensing without external brackets.
At 0.5 MPa it delivers 628 N pushing force and 528 N pulling force, rising to 1130 N push at 0.9 MPa. The 16 mm diameter piston rod and M12×1.25 rod thread handle moderate axial loads, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly. Total body length A is 142 mm, giving an extended length of approximately 205 mm for this 63 mm stroke model.

The 63 mm stroke and magnetic piston sensing make the SC40X63S ideal for diverters and gate actuators on packaging lines, where end-of-stroke confirmation is required for cycle sequencing.
With 628 N of push force at standard shop air and sensor-ready position feedback, this cylinder suits light-duty pneumatic clamping, drilling jigs, and assembly fixtures needing stroke verification.
The clean double-acting operation and magnetic sensing support automated sample handling, test-stand actuation, and small press mechanisms where stroke position must be monitored electronically.
Choose the SC40 bore when your application needs roughly 600-1100 N of push force. If you require more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact solution the SC32 provides 402 N. The 63 mm stroke is well within the 1200 mm maximum standard stroke for the 40 bore.
For replacement, match five points: 40 mm bore, 63 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and your required mounting accessory (this model ships basic, without brackets). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa the cylinder produces 628 N pushing and 528 N pulling. At 0.7 MPa it delivers 879 N push, and at the maximum operating pressure of 0.9 MPa it reaches 1130 N push. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix means a magnet is built into the piston, so you can fit AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods to detect piston position without extra mounting hardware.
