The AirTAC Airtac SC40 Standard Cylinder SC40X270SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 270mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X270SH double-acting cylinder delivers a push force of 628 N at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod. Its 270 mm stroke is well within the 1200 mm maximum standard stroke for the 40 mm bore, making it a readily available configuration.
Equipped with a built-in magnet (S suffix) and high-temperature Viton seals (H suffix), this unit operates reliably from 0 to +150 °C. The tie-rod construction keeps the overall body length compact at 142 mm plus stroke, and the adjustable pneumatic cushion at each end decelerates the piston smoothly over a 21 mm travel.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The Viton seals allow this cylinder to operate in ambient temperatures up to 150 °C, making it suitable for autoclaves, drying ovens, and foundry equipment.
With the built-in magnet, CMSG or DMSG sensors mount directly to the tie-rod barrel to provide precise end-of-stroke or mid-stroke position feedback for automated clamping fixtures.
Generating 628 N of force at standard shop air, this 270 mm stroke unit is ideal for diverting or pushing medium-weight packages on conveyor lines.
For applications needing more force, stepping up to the 50 mm bore provides 982 N of push at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 32 mm bore offers 402 N. This SC40X270SH features a PT1/4 port and M12x1.25 rod thread. When replacing, match five points: 40 mm bore, 270 mm stroke, PT thread, the built-in magnet, and the basic mounting style to ensure drop-in compatibility.
Quick checklist
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and port configuration.
