The AirTAC Airtac SC40 Standard Cylinder SC40X760SCB is a genuine double-acting standard air cylinder with a Ø40mm bore and 760mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X760SCB is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 40 mm bore and 760 mm stroke suit medium-duty linear tasks where a long reach is required, while the 16 mm diameter piston rod provides good column strength for the extended length.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The rear double clevis (CB) mount, ordered as accessory F-SC40CB, allows the cylinder to pivot during operation, absorbing misalignment in articulating linkages. Total extended body length is approximately 902 mm.

The 760 mm stroke and rear clevis mount suit long-travel gate or chute controls on farm machinery, with the magnet enabling end-of-travel sensing.
Pushes products across a wide conveyor. The CB mount lets the cylinder pivot as it extends, while the -S magnet confirms full extension and retraction.
Provides 628 N of lifting force for ergonomic assist arms. The double clevis mounting allows the cylinder to swing freely with the articulated linkage.
Choose the SC40 when your application needs roughly 628 N of force at standard plant air. If you require more power, the SC50 steps up to 982 N push at the same 0.5 MPa. For strokes of 760 mm, always evaluate side-loading: a 16 mm rod extended this far can bend under radial force. Use an external guide rail or switch to a guided cylinder if the load is not perfectly axial.
To replace an existing cylinder, match these five points: 40 mm bore, 760 mm stroke, PT1/4 port thread, rear double clevis (CB) mounting, and the built-in magnet (-S) for sensor compatibility. The SC is a tie-rod design and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the cylinder pushes with 628 N and pulls with 528 N. 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 in the model code means a magnet is built into the piston. You can clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect rod position.
