The AirTAC Airtac SC40 Standard Cylinder SC40X650 is a genuine double-acting standard air cylinder with a Ø40mm bore and 650mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X650 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration for mid-stroke applications. The 650 mm stroke is within the 1200 mm maximum standard range for this 40 mm bore.
With a compact body length A of 142 mm, the total extended length reaches approximately 792 mm. This genuine AirTAC SC cylinder uses PT1/4 ports and an M12x1.25 rod thread, making it a direct fit for standard pneumatic circuits requiring a balanced force-to-size ratio.

Operates diverter gates on conveyor lines, using the 650 mm stroke to shift product between lanes with consistent 628 N push force at standard line pressure.
Provides steady clamping pressure for woodworking or light metal fabrication jigs. The adjustable cushion reduces impact at the end of the 650 mm stroke, protecting the fixture.
Drives sorting arms or chute controls in processing equipment. The tie-rod design handles dusty environments when combined with proper rod sealing and filtration.
The SC40X650 suits applications needing around 628 N at standard plant pressure. If your load requires more force, stepping up to the 50 mm bore (SC50) provides 982 N at 0.5 MPa. For a lighter, more compact solution, the 32 mm bore (SC32) offers 402 N.
At 650 mm stroke, ensure the rod is not subjected to side loads. Long, unsupported strokes can cause rod bearing wear and bending. Use an external guide or linear rail to absorb transverse forces. For replacement, match bore (40 mm), stroke (650 mm), PT1/4 port thread, basic mount, and the absence of a magnet.
Quick checklist
At 0.7 MPa operating pressure, the SC40X650 cylinder generates 879 N of push force. The maximum push force at 0.9 MPa is 1130 N.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable. Only replace another AirTAC SC40 cylinder of the same stroke, port type, and mounting configuration.
