The AirTAC Airtac SC40 Standard Cylinder SC40X290 is a genuine double-acting standard air cylinder with a Ø40mm bore and 290mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X290 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, combining a 40 mm bore with a 290 mm stroke. It generates a push force of 628 N at 0.5 MPa and reaches 1130 N at the maximum operating pressure of 0.9 MPa, driven by a 16 mm diameter piston rod.
This model uses a PT1/4 port and includes an adjustable air cushion with a 21 mm cushion length to decelerate the piston smoothly. The body length A is 142 mm, giving a total extended length of approximately 432 mm. Standard TPU seals provide an operating temperature range of -20 to +70 °C.

The 290 mm stroke and 628 N push force at 0.5 MPa reliably actuates diverter gates on packaging conveyors, sorting lightweight cartons and parcels.
Delivers consistent 1130 N clamping force at 0.9 MPa for holding workpieces during light drilling, gluing, or assembly operations on jigs.
Uses the 290 mm stroke to tilt small parts bins, feeding components onto a chute or scale with controlled pneumatic actuation.
The SC40X290 suits applications needing moderate force in a compact tie-rod body. If your load requires more thrust, stepping up to the SC50 bore delivers 982 N push at 0.5 MPa. For lower force needs, the SC32 bore provides 402 N at the same pressure.
At a 290 mm stroke, ensure the rod is not subjected to significant side loads; an external linear guide or a guided cylinder is recommended to prevent rod bearing wear and bending. For replacement, match bore (40 mm), stroke (290 mm), PT1/4 port thread, basic mounting, and the absence of a magnet.
Quick checklist
At 0.7 MPa operating pressure, the SC40X290 produces a theoretical push force of 879 N. The pull force on the retract stroke at the same pressure is lower due to the 16 mm rod area.
No, this model does not include the -S magnet option. To use CMSG or DMSG sensors for piston position detection, you need the SC40X290-S variant, which has a built-in magnet band on the piston.
