The AirTAC Airtac SC40 Standard Cylinder SC40X630S is a genuine double-acting standard air cylinder with a Ø40mm bore and 630mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X630S delivers 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), driven by a 16 mm diameter piston rod through a 630 mm stroke. This tie-rod cylinder includes a built-in magnet, allowing CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for reliable end-of-stroke detection without external brackets.
The 40 mm bore SC series features a compact body length of 142 mm plus stroke, with PT1/4 ports and an M12x1.25 rod thread. Its 21 mm adjustable air cushion decelerates the piston smoothly at both ends, protecting the end caps during high-cycle operation.

The 630 mm stroke and 628 N push force at 0.5 MPa suit conveyor diverter gates and part stops. The built-in magnet provides clean sensor feedback for sequencing without external switch rails.
Delivers 1130 N of clamping force at 0.9 MPa across a 630 mm reach. The adjustable cushion protects tooling from impact shock during rapid clamp/unclamp cycles in machining cells.
Moves pallets or trays across a 630 mm transfer distance. The magnet-equipped barrel simplifies mounting CMSG reed switches for precise mid-stroke and end-stroke position confirmation.
For applications needing more force, stepping up to the 50 mm bore provides 982 N push at 0.5 MPa, while the 32 mm bore offers 402 N if a smaller footprint is required. At 630 mm stroke, ensure the rod is guided externally if side loads are present, as the 16 mm rod can experience bending moments under unsupported lateral forces.
When replacing an existing cylinder, match five points: 40 mm bore, 630 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. This model does not include mounting accessories; order F-SC40LB, FA, FB, CA, CB, or TC separately if a bracket is needed.
Quick checklist
At 0.5 MPa, the push force is 628 N and pull force is 528 N. At 0.7 MPa, push force rises to 879 N. The maximum push force at the 0.9 MPa operating limit is 1130 N. These values assume a standard double-acting circuit with the 16 mm rod diameter.
Yes. The -S suffix indicates a built-in magnet in the piston. AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors clamp directly onto the barrel tie-rods, eliminating the need for external actuator switches or mounting hardware.
