Caution
To select the correct bush and hub the external diameter of the outer hub should be sufficient to withstand the stresses exerted. To calculate the size, multiply the bush outside diameter by the relevant factor: Steel x 1.5, Cast Iron x 2.0, Aluminium x 2.5. If the selected hub diameter is greater than or equal to the calculated size, then the selected size is suitable.
