The AirTAC Airtac SC40 Standard Cylinder SC40X630 is a genuine double-acting standard air cylinder with a Ø40mm bore and 630mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X630 is a 40 mm bore double-acting tie-rod cylinder with a 630 mm stroke, delivering 628 N push and 528 N pull at 0.5 MPa. Its 16 mm diameter piston rod and 21 mm adjustable air cushion help manage end-of-stroke deceleration for consistent cycling in mid-force pneumatic applications.
With a body length A of 142 mm, the total extended length reaches approximately 772 mm. This model runs on filtered air at 0.15–1.0 MPa and uses standard PT1/4 ports with an M12x1.25 rod thread, making it a direct fit for fixtures designed around the AirTAC SC40 series.

The 630 mm stroke and 628 N push force at 0.5 MPa reliably divert cartons or trays across a wide packaging conveyor lane.
Moves machined parts between fixtures with a 16 mm rod providing adequate stiffness for guided transfer applications.
Operates sliding gates on agricultural hoppers or silos, using the 21 mm cushion to soften the stop under moderate loads.
The 40 mm bore suits applications needing between the 32 mm (402 N push at 0.5 MPa) and the 50 mm (982 N push) force classes. At 630 mm stroke the unsupported rod length is significant; side loads or high-speed cycling can induce rod bending, so an external linear guide or a guided cylinder should be considered if the load is not purely axial.
For direct replacement, match five points: 40 mm bore, 630 mm stroke, PT1/4 port thread, basic (no mounting accessory), and no magnet. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa 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. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder, so mounting dimensions and overall length differ. It is a direct replacement only for another AirTAC SC40 cylinder with the same bore, stroke, port thread, and mounting configuration.
