The AirTAC Airtac SC40 Standard Cylinder SC40X150LB 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 AirTAC SC40X150LB is a 40 mm bore double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 150 mm standard stroke is paired with a 16 mm diameter piston rod and M12x1.25 rod thread, offering a balanced combination of reach and column strength for medium-duty linear tasks.
This model includes the LB axial foot mount (F-SC40LB) for secure surface mounting. With a body length A of 142 mm and a 21 mm adjustable air cushion at each end, it decelerates the piston smoothly to reduce end-of-stroke impact. Operating pressure ranges from 0.15 to 1.0 MPa with filtered air.

The 150 mm stroke and 628 N push force at 0.5 MPa reliably actuates package diverters and sorting gates on medium-speed conveyor lines.
Used in jigs and fixtures for part clamping during machining or assembly, where the LB foot mount provides stable, rigid alignment.
Operates chutes, hatches, and levers on farming equipment, with TPU seals rated for -20 to +70 °C and standard PT ports.
Choose the SC40 bore when your application needs roughly 628 N of force at standard plant pressure; if you need more force, stepping up to the SC50 bore provides 982 N at the same 0.5 MPa. For strokes of 300 mm or longer on this 16 mm rod, evaluate side-load conditions carefully—an external guide or guided cylinder is recommended to protect the rod bearing from bending moments.
When replacing an existing cylinder, match five points: 40 mm bore, 150 mm stroke, PT1/4 port thread, the LB foot mounting (F-SC40LB), and confirm whether your application requires the optional built-in magnet (this model does not include the -S magnet).
Quick checklist
At 0.5 MPa the cylinder provides 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 force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is dimensionally shorter than an ISO 15552 profile cylinder, so it is not a drop-in interchange. It replaces another AirTAC SC40 cylinder with matching bore, stroke, PT ports, and LB foot mount.
