The AirTAC Airtac SC40 Standard Cylinder SC40X80SCB is a genuine double-acting standard air cylinder with a Ø40mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X80SCB is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With an 80 mm stroke and a 16 mm diameter piston rod, it suits compact linear actuation tasks where moderate force and a pivoting rear mount are required.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The CB suffix specifies a rear double clevis (fork) mount, supplied as part F-SC40CB, allowing the cylinder body to pivot during operation. Seals are standard TPU for a -20 to +70 °C working range, and ports are PT1/4.

The 40mm bore provides ample force for pneumatic clamps and workholding fixtures in machining centers, with the rear clevis mount allowing the cylinder to align itself as the clamp engages.
Ideal for actuating diverter gates on conveyor lines. The double clevis mount handles the pivoting motion, while the magnetic piston enables end-of-stroke sensing for reliable sorting control.
Used to control chutes or levers on planting and harvesting equipment. The TPU seals and tie-rod construction offer durability in dusty conditions, and the sensor confirms gate position remotely.
Choose the SC40 bore for applications needing up to 628 N at 0.5 MPa. If your load requires more force, step up to the SC50 bore (982 N at 0.5 MPa); for a lighter, more compact solution, the SC32 bore provides 402 N. The 80 mm stroke is a standard length within this series.
To ensure a direct replacement, match five key points: bore (40 mm), stroke (80 mm), port thread (PT1/4), mounting accessory (rear double clevis CB), and the built-in magnet (-S). This tie-rod cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa (5 bar), the cylinder pushes with 628 N and pulls with 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It will only directly replace another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, and mounting type.
