The AirTAC Airtac SC40 Standard Cylinder SC40X210S is a genuine double-acting standard air cylinder with a Ø40mm bore and 210mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X210 is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (879 N at 0.7 MPa). Its 40 mm bore and 210 mm stroke suit medium-duty linear tasks where a compact footprint is needed, and the 16 mm diameter piston rod provides good rigidity for straight-line actuation.
This model features an adjustable air cushion (21 mm length) at both ends to decelerate the piston smoothly, reducing end-of-stroke impact. The body length A is 142 mm, making the total extended length approximately 352 mm. It uses PT1/4 ports and operates on filtered air from 0.15 to 1.0 MPa.

The 210 mm stroke and 628 N push force at 0.5 MPa reliably actuate gates and diverters on medium-speed packaging lines, sorting cartons by size or destination.
Applies consistent, controlled clamping pressure for woodworking or light metal fabrication jigs. The 16 mm rod resists deflection under the direct axial loads typical in fixturing.
Operates louvres and dampers in agricultural ventilation systems. The TPU seals handle the standard -20 to +70 °C temperature range, and the double-acting function provides positive open/close control.
Choose the SC40X210 when your application needs around 628 N of push force at standard plant pressure. If you require more force, stepping up to the SC50 bore provides 982 N at the same 0.5 MPa. For lighter, faster cycling, the SC32 bore offers 402 N.
For a drop-in replacement, match five key points: 40 mm bore, 210 mm stroke, PT1/4 port thread, basic (no bracket) mounting, and no magnet. Always verify the tie-rod body length (A=142 mm) and port location against your existing setup, as the SC series is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At the standard operating pressure of 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 force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder and is physically shorter than an ISO 15552 cylinder of the same bore and stroke. It is not dimensionally interchangeable. Only use it to replace another AirTAC SC tie-rod cylinder with identical bore, stroke, port thread, and mounting.
