The AirTAC Airtac SC40 Standard Cylinder SC40X63 is a genuine double-acting standard air cylinder with a Ø40mm bore and 63mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X63 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa, scaling up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 63 mm stroke, this unit is built for short, repetitive linear moves where space is tight but reliable force is still required.
Its 16 mm diameter piston rod and 21 mm adjustable air cushion at each end provide smooth deceleration, protecting end caps and tooling from impact. The body length A is 142 mm, making the total extended length approximately 205 mm. This model uses standard PT1/4 ports and operates on filtered air from -20 to +70 °C with its default TPU seals.

The 63 mm stroke and 628 N push force at 0.5 MPa are well-suited for stopping or diverting small packages on light-duty conveyors, providing a firm, repeatable action.
Ideal for pneumatic clamping jigs, the 16 mm rod and compact 205 mm extended length fit neatly into workholding stations, applying consistent pressure during machining or assembly.
Use this cylinder to eject finished goods from a packaging line. The adjustable cushion reduces noise and vibration, preserving the mechanism over millions of cycles.
For applications needing more force, stepping up to the 50 mm bore SC50 series provides 982 N of push at the same 0.5 MPa pressure. If space is the primary constraint, the 32 mm bore SC32 offers 402 N. This SC40X63 is a basic configuration with no built-in magnet, no mounting accessories, standard TPU seals, and PT threads.
When replacing an existing cylinder, match five key points to ensure drop-in compatibility: bore (40 mm), stroke (63 mm), port thread (PT1/4), mounting style (basic), and magnet option (none). The SC is a tie-rod design 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.
This specific model code SC40X63 does not include the -S suffix, so it is supplied without a built-in magnet. To use CMSG or DMSG sensors, you would need to order the SC40X63-S variant, which has a magnetised piston for sensor compatibility.
