The AirTAC Airtac SC40 Standard Cylinder SC40X275SN is a genuine double-acting standard air cylinder with a Ø40mm bore and 275mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X275SN is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 275 mm stroke is well within the 1200 mm maximum standard range for the 40 mm bore, making this a standard-configuration actuator. The built-in magnet allows easy mounting of CMSG/DMSG/EMSG reed or solid-state sensors directly onto the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback.
This model is fitted with NBR (nitrile) seals, suitable for general industrial environments within the standard -20 to +70 °C temperature range. The 16 mm diameter piston rod and PT1/4 port ensure a robust connection for pneumatic tubing, while the adjustable air cushion at each end decelerates the piston smoothly, reducing impact noise and wear. The body length A is 142 mm, giving a total extended length of approximately 417 mm.

Actuates diverter gates on conveyor lines. The 275 mm stroke provides ample travel for sorting small to medium packages, with magnetic sensors confirming gate position.
Powers clamping and pressing fixtures in assembly cells. The 628 N force at 0.5 MPa is ideal for holding parts during gluing or ultrasonic welding processes.
Operates chutes and flow control gates on seeders or fertilizer spreaders. NBR seals and the robust tie-rod design handle dusty agricultural environments reliably.
Choose the SC40 bore when your application requires a push force between 500 and 900 N at typical plant pressures. If your load demands more force, stepping up to the SC50 bore provides 982 N of push at 0.5 MPa. For a lighter, more compact solution, the SC32 bore delivers 402 N. This 275 mm stroke cylinder uses a basic mount; for surface mounting, select the LB foot bracket (F-SC40LB), or for pivoting motion, the TC centre trunnion (F-SC40TC).
To ensure a correct replacement, match five key points: 40 mm bore, 275 mm stroke, PT1/4 port thread, the built-in magnet (-S), and the NBR seal material. The SC series is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 0.5 MPa, this cylinder produces 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG sensors directly to the tie-rod barrel for non-contact position sensing.
