The AirTAC Airtac SC40 Standard Cylinder SC40X50SCA is a genuine double-acting standard air cylinder with a Ø40mm bore and 50mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X50SCA is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a compact 50 mm stroke, it uses a 16 mm diameter piston rod and PT1/4 ports, making it a responsive actuator for short, repetitive linear moves.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and a rear single clevis mount (CA, part F-SC40CA) that allows the cylinder body to pivot during operation. The adjustable air cushion at each end decelerates the 21 mm cushion stroke smoothly, reducing end-of-travel impact.

The built-in magnet and rear clevis mount allow this cylinder to pivot into a clamping position, with magnetic sensors confirming full extension and retraction for automated quality checks.
Use the SC40X50SCA to actuate a small diverter gate on a conveyor line. The rear clevis accommodates the arc of motion, while the 50 mm stroke provides a clean, fast sorting action.
Ideal for life-cycle test rigs, this cylinder's 628 N force at 0.5 MPa applies a consistent, repeatable load. Magnetic sensors provide cycle counts and end-of-stroke verification to the control system.
Choose the SC40 for applications needing up to 628 N at standard plant pressure. If your load is lighter, the SC32 provides 402 N in a smaller footprint; for heavier demands, step up to the SC50 at 982 N. This 50 mm stroke is well within the 1200 mm maximum standard stroke for bore 40.
To ensure a correct replacement, match five points: 40 mm bore, 50 mm stroke, PT1/4 port thread, the rear clevis mounting accessory (F-SC40CA), and the built-in magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the theoretical push force is 628 N and the pull force is 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 cylinder. It is not dimensionally interchangeable. It is a direct replacement only for another AirTAC SC tie-rod cylinder with matching bore, stroke, port thread, rear clevis mount, and magnet option.
