Ball size loading capacity and the effective load placed on each ball transfer units are normally provided by the weight of charge divided by 3. The result gives the highest load which any individual ball transfer units may support. it is important that the load is supported through the centre line of the unit; the load carrying capacity is much affected by downwards and sidewards applications, so a suitable security charge margin is s ested.

In order to determine the distance between the ball transfer units, divide the shortest horizontal distance of the load by 2.5m. for example, for a weight measuring across the base 500mm x 1000mm the recommended distance will be 200mm (500:2.50). this is the distance among the units that guarantees enough ball transfer units on the shortest side of the load.

The units can be usually placed in three different ways:

A). SQUARED PITCH
B). DIAMOND PITCH
C). EXTENDED PITCH
