The AirTAC SC50 Standard Cylinder SC50X75SCB is a genuine double-acting standard air cylinder with a Ø50mm bore and 75mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X75SCB is a 50 mm bore, 75 mm stroke double-acting tie-rod cylinder delivering 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa). Its 20 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration in a compact body length of 150 mm.
This model is factory-configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors and a rear double clevis (CB) bracket, part F-SC50CB. The combination allows pivoting actuation with full electronic stroke confirmation, supplied as a genuine AirTAC assembly ready for immediate installation.

The 75 mm stroke and rear clevis mount suit pivoting diverter gates on packaging conveyors. The built-in magnet allows end-of-stroke sensors to confirm gate position at every cycle.
Ideal for swinging a clamp arm into place on a welding or assembly fixture. The CB clevis handles the arcing motion, while the 982 N force securely holds the workpiece during processing.
Operates a discharge chute on a seed or grain hopper. The pivoting action and sensor feedback ensure the chute opens and closes fully, preventing material spillage.
Choose the SC50 when your application needs roughly 1000 N of force at standard shop air. If the load is lighter, stepping down to a 40 mm bore (628 N at 0.5 MPa) saves space; for heavier demands the 63 mm bore provides 1559 N. The 75 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
To replace an existing cylinder, match five points: 50 mm bore, 75 mm stroke, PT1/4 port thread, CB rear double clevis mounting, and the -S magnet. The SC is a tie-rod design, not an ISO 15552 profile, so verify the shorter body length A of 150 mm against your mounting envelope.
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, push force reaches 1767 N. The theoretical maximum at 1.0 MPa is 200 kgf.
Yes. The -S suffix denotes a built-in magnet, so CMSG reed switches or DMSG/EMSG solid-state sensors clip directly onto the barrel tie-rods for non-contact position sensing.
