The AirTAC Airtac SC40 Standard Cylinder SC40X600SFA is a genuine double-acting standard air cylinder with a Ø40mm bore and 600mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X600SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa, making it a capable mid-bore actuator for medium-duty linear tasks. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration, while the 600 mm stroke suits extended transfer and positioning operations.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise, non-contact position feedback along the barrel. The FA front rectangular flange (accessory F-SC40FA) allows secure panel or bulkhead mounting on the rod end, simplifying integration into machine frames.

The 600 mm stroke reliably shuttles components between conveyor lines or workstations, with magnetic sensors confirming end-of-travel positions for automated sequencing.
Delivers up to 1130 N at 0.9 MPa for light pressing, staking, or clamping operations in assembly fixtures, where the front flange mount ensures rigid alignment.
Actuates diverter gates on packaging or logistics lines. The adjustable cushion minimizes impact noise and vibration at high cycle rates, extending mechanism life.
Select the 40 mm bore when your application needs between 528 N and 628 N of force at standard plant pressure. For higher force requirements, stepping up to the 50 mm bore provides 982 N push at 0.5 MPa. The 600 mm stroke is well within the 1200 mm maximum standard stroke for this bore, ensuring standard lead times.
For strokes of this length, avoid unsupported side loads which can cause rod bending and premature bearing wear. Use an external linear guide or a guided cylinder to absorb transverse forces. For a direct replacement, match the 40 mm bore, 600 mm stroke, PT port thread, front flange mounting (FA), and the integrated magnet (-S) for sensor compatibility.
Quick checklist
At the standard 0.5 MPa operating 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 increases to 1130 N.
Yes, provided the existing unit matches the 40 mm bore, 600 mm stroke, PT port thread, and front flange mounting style. The built-in magnet (-S) allows drop-in use with CMSG/DMSG sensors. Always verify the front flange bolt pattern against the F-SC40FA accessory drawing.
