The AirTAC Airtac SC40 Standard Cylinder SC40X620S is a genuine double-acting standard air cylinder with a Ø40mm bore and 620mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X620S is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 620 mm stroke suits medium-reach material transfer and clamping tasks, with a 16 mm diameter piston rod providing solid column strength.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly onto the tie-rod barrel for contactless position sensing. The cylinder operates on filtered air from 0.15 to 1.0 MPa across a standard temperature range of -20 to +70 °C with TPU seals.

Extends 620 mm to push or lift products between conveyor lines, with sensor magnets confirming end-of-stroke position in automated cells.
Applies 628 N at 0.5 MPa to hold workpieces during machining or assembly, with CMSG/DMSG sensors verifying clamp engagement.
Drives a 620 mm stroke in case erectors or pallet dispensers, where the built-in magnet simplifies sensor mounting on the barrel.
Choose the SC40 bore for push forces around 628 N at 0.5 MPa; if your load requires roughly 982 N, step up to the SC50 bore. For this 620 mm stroke, ensure the 16 mm rod is not subjected to high side loads—long unsupported strokes can cause rod bending. Use an external linear guide or a guided cylinder if lateral forces are present. When replacing, match bore (40 mm), stroke (620 mm), PT port thread, the built-in magnet (-S), and the basic tie-rod mounting configuration exactly.
Quick checklist
At 0.5 MPa supply pressure, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 1130 N.
Match the 40 mm bore, 620 mm stroke, PT port thread, and the built-in magnet (S suffix). The SC is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to another AirTAC SC of the same specifications.
