The AirTAC SC40 Standard Cylinder SC40X750SCB is a genuine double-acting standard air cylinder with a Ø40mm bore and 750mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X750SCB is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore, 16 mm piston rod, and a 750 mm stroke, it suits medium-reach linear tasks where the cylinder body must pivot at the cap end.
The built-in magnet (suffix S) allows CMSG/DMSG/EMSG sensors to clamp directly onto the barrel for rod-position feedback. A rear double clevis mount (CB, using bracket F-SC40CB) lets the cylinder swing through an arc, while the 21 mm adjustable air cushion at each end decelerates the piston smoothly. Total extended length is approximately 892 mm (body length A=142 mm + stroke).

The 750 mm stroke and rear clevis mount allow the cylinder to swing a diverter gate on packaging or sortation conveyors, with magnetic sensors confirming gate position at each end of travel.
In welding or assembly jigs, the CB mount lets the cylinder body pivot as it extends 750 mm to close a clamp. The 1130 N force at 0.9 MPa provides firm holding pressure during the cycle.
Operates a discharge chute on agricultural hoppers. The double clevis mounting handles the pivoting motion, and the magnetic piston enables end-of-stroke detection for automated fill systems.
Choose the SC40 bore when your application needs 628 N at 0.5 MPa. If you require more force, step up to the SC50 (982 N at 0.5 MPa); for a lighter, more compact option, the SC32 provides 402 N. At 750 mm stroke, the 16 mm rod is slender—avoid direct side loads. If the rod must guide or support a transverse force, pair the cylinder with an external linear guide or switch to a guided-cylinder assembly.
For a direct replacement, match five points: 40 mm bore, 750 mm stroke, PT port thread, rear double clevis (CB) mounting, and the built-in magnet (-S). This model is a genuine AirTAC SC tie-rod cylinder, not an ISO 15552 profile unit, so dimensional interchangeability is limited to another AirTAC SC40 with the same configuration.
Quick checklist
At 0.5 MPa, the cylinder produces 628 N extending (push) and 528 N retracting (pull). At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet on the piston. You can clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect rod position without additional brackets.
