The AirTAC SC50 Standard Cylinder SC50X740SCB is a genuine double-acting standard air cylinder with a Ø50mm bore and 740mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X740SCB is a double-acting tie-rod cylinder with a 50 mm bore and a 740 mm stroke, delivering a push force of 982 N at 0.5 MPa and up to 1767 N at 0.9 MPa. This model features a 20 mm diameter piston rod with M16x1.5 threads and an adjustable air cushion length of 21 mm to decelerate the piston smoothly at end of travel.
Configured with a built-in magnet (-S suffix), it accepts CMSG/DMSG/EMSG sensors for direct barrel-mounted position feedback. The rear double clevis mount (CB suffix, bracket F-SC50CB) allows the cylinder to pivot during operation, making it suitable for articulated linkages. The body length A is 150 mm, giving a total extended length of approximately 890 mm.

The 740 mm stroke and rear clevis mount suit pivoting diverter gates on conveyors, where the 982 N force at 0.5 MPa reliably directs packages or bulk materials.
With a built-in magnet for sensor confirmation and a pivoting double clevis mount, this cylinder works in welding jigs requiring long-reach clamping and position verification.
The tie-rod construction and 1767 N maximum thrust at 0.9 MPa provide durable power for raising or adjusting heavy attachments on farm machinery with a pivoting linkage.
Select the SC50 bore for pneumatic applications needing 982 N of push force at 0.5 MPa. For higher force, step up to the SC63 bore which provides 1559 N at the same pressure. For a lower force class, the SC40 bore delivers 628 N. At a 740 mm stroke, ensure the rod is protected from side loads; consider an external linear guide or a guided cylinder to prevent rod bending and premature bearing wear.
To replace an existing unit, match five key points: 50 mm bore, 740 mm stroke, PT port threads, CB rear double clevis mounting, and the integrated magnet for sensor compatibility. This tie-rod cylinder is not an ISO 15552 profile and is dimensionally shorter, so it is not a direct replacement for those standard cylinders.
Quick checklist
At 0.7 MPa operating pressure, the theoretical push force is 1374 N and the pull force on the retract stroke is 1155 N (calculated from the 20 mm rod area). The maximum push force at 0.9 MPa is 1767 N.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. The mounting dimensions, body length, and accessory interfaces differ. It is a direct replacement only for another AirTAC SC50 tie-rod cylinder with matching stroke, PT ports, CB rear clevis mount, and magnet option.
