Shafts in tension will not bend however, shafts in compression can bend. Check out our shaft buckling load calculator below.

Long stroke cylinders may require larger shafts to prevent buckling under compression. Eulers formula below is often used to calculate the appropriate shaft diameter and maximum load with different mounting methods.

Please note: these calculations are guides only – you may be required to contact a Registered Consulting Engineer for your application.

Stroke & closed centres given the open centres

Tip: use either mm or inches for this calculator and the result will be in the same unit (do not mix units).

A = Open centre

B = Dead length = + + + + + =

Stroke = ( -B )/2=

Closed centre = stroke+B= (minimum possible, can be more)

Open & closed centres given the mid position

Tip: use either mm or inches for this calculator and the result will be in the same unit (do not mix units).

A = Mid position A

B = + + + + + =

Stroke = ( -B )÷1.5=

Closed centre = stroke+B=

Open centre=closed centre+stroke=
