The AirTAC Airtac SC40 Standard Cylinder SC40X310S is a genuine double-acting standard air cylinder with a Ø40mm bore and 310mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X310S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 310 mm stroke suits medium-reach material transfer, pressing, and clamping tasks where consistent pneumatic power is needed.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for contactless position sensing. The 40 mm bore uses a 16 mm diameter piston rod with M12x1.25 threads and PT1/4 ports. Adjustable air cushioning at both ends decelerates the piston over a 21 mm cushion length, reducing end-of-stroke impact.

Pushes or diverts boxes and totes on conveyor lines. The 310 mm stroke reaches across standard roller beds, and the magnetic piston enables end-of-stroke confirmation with barrel-mounted sensors.
Provides 628 N at 0.5 MPa for pressing bushings, bearings, or dowels into light alloy housings. Adjustable cushioning protects the assembly tooling from impact damage.
Operates a stop gate or diverter flap in packaging machinery. The built-in magnet allows the control system to verify gate position, preventing jams and misfeeds.
For higher force at the same pressure, step up to the 50 mm bore (982 N at 0.5 MPa); for a lighter, more compact actuator, the 32 mm bore provides 402 N. At 310 mm stroke, ensure the rod is not subjected to significant side loads—if lateral forces are present, add an external linear guide or consider a guided cylinder to protect the rod bearing and seals.
When replacing an existing cylinder, match five points: 40 mm bore, 310 mm stroke, PT1/4 port thread, the built-in magnet for sensor compatibility, and the basic (no bracket) mounting. This SC is a tie-rod design, not an ISO 15552 profile cylinder, so dimensional interchangeability is limited to another AirTAC SC or equivalent tie-rod unit.
Quick checklist
At the standard 0.5 MPa operating pressure, the cylinder produces 628 N pushing force and 528 N pulling force. At 0.7 MPa, push force increases to 879 N, and at the maximum operating pressure of 0.9 MPa, it reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a magnet is built into the piston, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clip directly onto the barrel's sensor grooves. No external brackets or modifications are needed.
