The AirTAC Airtac SC40 Standard Cylinder SC40X630SLB 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 AirTAC SC40X630SLB is a double-acting single-rod pneumatic cylinder with a 40 mm bore and a 630 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. Its 16 mm diameter rod and 21 mm adjustable air cushion provide smooth deceleration for mid-range linear tasks.
This model is equipped with a built-in magnet (suffix S) for direct mounting of CMSG/DMSG/EMSG sensors, and comes with an LB axial foot mount (accessory F-SC40LB) for secure surface installation. The standard PT ports and TPU seals suit normal operating temperatures from -20 to +70 °C.

The 630 mm stroke and 628 N push force at 0.5 MPa reliably divert cartons on a conveyor, with the LB foot mount providing a stable base.
Moves components between fixtures in a machine tool, where the built-in magnet allows end-of-stroke sensing to confirm part transfer.
Operates a long-reach diverter gate in a logistics system, using sensor feedback to ensure full open/close cycles.
For higher force, step up to the 50 mm bore which provides 982 N push at 0.5 MPa; for a more compact unit, the 32 mm bore offers 402 N. The 630 mm stroke is within the 1200 mm maximum standard stroke for bore 40. When using a stroke of this length, avoid direct side loads on the unsupported rod—consider an external linear guide or a guided cylinder if lateral forces are present. To replace this cylinder, match the 40 mm bore, 630 mm stroke, PT port thread, LB foot mount, and the built-in magnet feature.
Quick checklist
At 0.5 MPa, it produces 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes, the -S suffix denotes a built-in magnet, allowing AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors to be clamped directly onto the barrel for position feedback.
