The AirTAC Airtac SC40 Standard Cylinder SC40X430 is a genuine double-acting standard air cylinder with a Ø40mm bore and 430mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X430 is a double-acting pneumatic cylinder with a 40 mm bore and 430 mm stroke, delivering a push force of 628 N 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-range linear motion tasks.
This tie-rod cylinder has a compact body length of 142 mm, resulting in a total extended length of approximately 572 mm. The PT1/4 port and M12x1.25 rod thread make it straightforward to plumb and connect, while the TPU seals ensure consistent operation from -20 to +70 °C.

Operates diverter gates on packaging conveyors, using the 430 mm stroke to redirect products between lanes with controlled cushioning at end-of-travel.
Provides 628 N of clamping force at standard line pressure for woodworking or light metal fabrication jigs, holding workpieces securely during machining.
Drives sorting paddles or chutes in seed and produce handling equipment, where the 40 mm bore offers a good balance of speed and force for repetitive actuation.
For applications needing slightly more force, the 50 mm bore SC50 delivers 982 N at 0.5 MPa. If space or weight is a concern, the 32 mm bore SC32 provides 402 N. At 430 mm stroke, the 16 mm rod is well-supported within the standard range, but any side loading should be managed with an external guide to prevent rod bearing wear.
To replace an existing SC40X430, match the 40 mm bore, 430 mm stroke, PT1/4 port thread, and basic mounting configuration. If the original unit included a magnet for sensors, ensure the replacement carries the -S suffix.
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 overall body length than an ISO 15552 profile cylinder. It is dimensionally interchangeable only with another AirTAC SC tie-rod cylinder of the same bore, stroke, and port thread.
