The AirTAC Airtac SC40 Standard Cylinder SC40X660S is a genuine double-acting standard air cylinder with a Ø40mm bore and 660mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X660S is a tie-rod double-acting cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 660 mm stroke suits automated handling tasks requiring extended linear reach, such as material transfer or pushing mechanisms.
A built-in magnet allows CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for precise end-of-stroke detection. The 16 mm diameter piston rod and 21 mm adjustable air cushion ensure smooth deceleration, while the PT1/4 port provides reliable pneumatic connection.

Extends to push or divert products between conveyor lines, with sensor feedback confirming full extension and retraction.
Provides consistent linear force for pressing components or inserting parts in automated assembly cells.
Operates carton flaps or pusher arms in packaging stations, where the 660 mm stroke handles deep case packing.
For applications needing slightly more force, consider stepping up to the SC50 bore, which provides 982 N at 0.5 MPa. If a shorter, more compact cylinder is sufficient, the SC32 offers 402 N. At 660 mm, the stroke is well within the 1200 mm maximum standard stroke for this 40 mm bore. When replacing, match bore, stroke, PT port thread, the -S magnet option, and the basic mounting configuration to ensure 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.
The -S suffix indicates a built-in magnet. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder barrel's sensor slot to detect piston position.
