The AirTAC Airtac SC40 Standard Cylinder SC40X80SH 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 SC40X80SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 80 mm stroke suits short clamping, pressing, and ejecting tasks in high-temperature zones. The built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for reliable end-of-stroke detection.
This model features Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for autoclaves, foundries, and drying lines. The 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth deceleration. It uses a PT1/4 port and M12x1.25 rod thread, with a compact body length of 142 mm.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals withstand 150°C steam cycles, making this cylinder ideal for actuating doors, locks, and lifts in medical and food-grade sterilizers.
Delivers 1130 N of force at 0.9 MPa for consistent pressure in heated platen presses, thermoforming tools, and composite curing molds.
The magnetic piston enables sensor feedback for precise positioning of hot parts on conveyors exiting ovens or paint drying lines.
Choose the SC40 bore for general automation when 628 N at 0.5 MPa is sufficient. If you need more force, the SC50 delivers 982 N at the same pressure. For lighter, faster applications, the SC32 provides 402 N. This 80 mm stroke is well within the standard range, ensuring quick availability.
For replacement, match five points: 40 mm bore, 80 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the Viton seal (-H suffix). The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profiles.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder provides 628 N pushing force and 528 N pulling force. At the maximum operating pressure of 0.9 MPa, the pushing force increases to 1130 N.
No. The AirTAC SC series is a tie-rod cylinder and its body length (142 mm for the SC40) is shorter than an equivalent ISO 15552 cylinder. You must use mounting accessories specifically designed for the SC series, such as the F-SC40LB foot mount or F-SC40FA front flange.
