The AirTAC Airtac SC40 Standard Cylinder SC40X150SLB is a genuine double-acting standard air cylinder with a Ø40mm bore and 150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X150SLB is a double-acting pneumatic cylinder with a 40 mm bore and 150 mm stroke, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at 0.9 MPa. This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors and an LB foot mounting bracket (F-SC40LB) for secure surface installation.
Designed as a robust tie-rod cylinder, the SC40X150SLB uses a 16 mm diameter piston rod with an M12x1.25 thread and PT1/4 ports. The adjustable air cushion, with a 21 mm cushion length, decelerates the piston smoothly at the end of its stroke, reducing impact and vibration in automated systems.

The 150 mm stroke and 628 N push force at 0.5 MPa are ideal for actuating part stops or diverting gates on light-to-medium duty conveyor lines, with sensor confirmation via the built-in magnet.
Delivers consistent clamping force for woodworking or light metal fabrication jigs. The LB foot mount provides a stable, rigid base, while the adjustable cushion protects the fixture from hammering.
Operates sliding gates on small agricultural hoppers or seed dispensers. The magnetic piston allows position feedback to confirm full open or closed status, preventing material spillage.
Choose the SC40 bore for applications requiring up to 628 N of push force at standard plant pressure. If your load demands more force, stepping up to the SC50 bore provides 982 N at 0.5 MPa. For precise end-of-stroke sensing, the integrated magnet allows tool-free clamping of reed or solid-state sensors directly onto the barrel tie-rods.
When replacing an existing cylinder, ensure a 5-point match: 40 mm bore, 150 mm stroke, PT1/4 port thread, LB foot mounting (F-SC40LB), and the built-in magnet (-S). This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC series units of the same configuration.
Quick checklist
At 0.5 MPa, the cylinder provides 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet inside the piston. This allows you to clamp CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the cylinder's tie-rod barrel to detect piston position without any additional brackets.
