The AirTAC Airtac SC40 Standard Cylinder SC40X1500 is a genuine double-acting standard air cylinder with a Ø40mm bore and 1500mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1500 is a double-acting tie-rod cylinder with a 40 mm bore and an extended 1500 mm stroke. This non-standard stroke length exceeds the standard maximum of 1200 mm for the 40 mm bore, making it a made-to-order configuration for applications requiring a long linear reach. At 0.5 MPa operating pressure, the cylinder generates 628 N of push force and 528 N of pull force, with a 16 mm diameter piston rod and PT1/4 port connections.
With a body length A of 142 mm, the total extended length of this cylinder is approximately 1642 mm. The adjustable pneumatic cushion at each end (21 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact. This model features the standard TPU/NBR seal package suitable for a temperature range of -20 to +70 °C and standard PT threads. The long stroke demands careful attention to side-load management to prevent rod bending.

The 1500 mm stroke moves lightweight parts or diverters across wide conveyor gaps, ideal for packaging and logistics lines where space is available for a tie-rod cylinder.
Provides a steady 628 N push at 0.5 MPa to traverse a dispensing head over a large panel, delivering consistent adhesive beads in furniture or automotive trim assembly.
Operates a tall hopper door or air damper with a controlled stroke, using the adjustable cushion to softly stop the 16 mm rod at each end of its 1500 mm travel.
Select the SC40X1500 when your application needs a 1500 mm stroke with a push force around 628 N at 0.5 MPa. If you require higher force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at the same pressure. For lower force requirements, the 32 mm bore SC32 series offers 402 N. This cylinder is a direct replacement only for another AirTAC SC40 tie-rod cylinder with matching bore, stroke, PT1/4 ports, and basic mounting.
For any stroke of 300 mm or more, and especially at 1500 mm, the 16 mm rod is susceptible to bending under side loads. Always use an external linear guide or a guided cylinder assembly to absorb transverse forces and protect the rod bearing and seals from premature wear.
Quick checklist
At the standard operating pressure of 0.5 MPa, the SC40X1500 delivers 628 N of push force and 528 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No, it is strongly recommended to use an external guide. The 16 mm diameter rod on a 1500 mm stroke is highly vulnerable to bending and buckling under side loads or high acceleration. An external guide rail or rodless guided cylinder system will absorb transverse forces and ensure reliable operation.
