The AirTAC Airtac SC40 Standard Cylinder SC40X1840S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1840mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1840 is a double-acting tie-rod cylinder with a 40 mm bore and an extra-long 1840 mm non-standard stroke, delivering a push force of 628 N at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and PT1/4 ports suit mid-range pneumatic tasks requiring extended linear reach.
This model features a 21 mm adjustable air cushion at each end to decelerate the piston smoothly, and the body length A measures 142 mm. As a made-to-order stroke exceeding the standard 1200 mm maximum, it is built specifically for applications where a compact bore must span a large distance.

Pushes or pulls lightweight trays and components across wide conveyor gaps, where a 1840 mm stroke bridges distant pick-and-place points without a larger bore.
Operates remote clamping or cutting tools in jigs and fixtures, using the 40 mm bore’s force to hold parts securely at the end of a long linear stroke.
Drives tall diverter gates or flaps in sorting systems, where the slim cylinder profile fits narrow channels and the long stroke provides full gate articulation.
Choose the SC40 when the 32 mm bore’s 402 N push at 0.5 MPa is insufficient, but the 50 mm bore’s 982 N is excessive for your load. For this 1840 mm stroke, side-load management is critical—an unsupported 16 mm rod at full extension is vulnerable to bending; use an external linear guide or rod-alignment coupler to protect the rod bearing and seals. When replacing, match bore (40 mm), stroke (1840 mm), PT1/4 port thread, basic mounting, and the absence of a magnet to ensure identical fit and performance.
Quick checklist
At 0.5 MPa it provides 628 N pushing and 528 N pulling. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The maximum standard stroke for a 40 mm bore SC cylinder is 1200 mm. The 1840 mm stroke is a non-standard, made-to-order length, so lead times may differ from standard-stroke models.
