The AirTAC Airtac SC40 Standard Cylinder SC40X610 is a genuine double-acting standard air cylinder with a Ø40mm bore and 610mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X610 is a double-acting pneumatic cylinder with a 40 mm bore and a 610 mm non-standard stroke, extending the standard 1200 mm maximum capability for this bore size. At 0.5 MPa it provides a push force of 628 N and a pull force of 528 N, driven by a 16 mm diameter piston rod with an M12x1.25 rod thread.
This tie-rod cylinder features an adjustable pneumatic cushion (21 mm length) at both ends to decelerate the piston near stroke end. The body length A is 142 mm, making the total extended length approximately 752 mm. Operating pressure ranges from 0.15 to 1.0 MPa with filtered air, and the standard TPU seals suit a temperature range of -20 to +70 °C.

The 610 mm stroke moves components between distant conveyor lanes or workstations. The 16 mm rod provides adequate column strength for on-axis pushing in automated assembly lines.
Operates a tall sliding gate or diverter chute in material handling. The adjustable cushion softens the stop at both ends, reducing wear when the gate hits its end-of-travel.
Provides extended reach for a clamping arm in a welding or machining fixture. The 628 N push force at 0.5 MPa securely holds parts, but external guides are required to manage off-axis clamping loads.
For applications needing slightly less force, the 32 mm bore SC32 series delivers 402 N push at 0.5 MPa, while stepping up to the 50 mm bore SC50 provides 982 N. With a 610 mm stroke, this cylinder has a significant unsupported rod length; ensure the load is guided externally or use a guided cylinder to prevent rod bending and premature bearing wear under side loads.
To replace this cylinder, match five key points: the 40 mm bore, the 610 mm stroke, the PT1/4 port thread, the basic (no bracket) mounting configuration, and the absence of a built-in magnet. This model is not dimensionally interchangeable with ISO 15552 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 SC40X610 is not designed for unsupported side loads. The 16 mm rod is susceptible to bending at this extended length. You must use an external linear guide, rod alignment coupler, or switch to a guided cylinder to prevent premature seal and bearing failure.
