Quantity layoutThe pitch is calculated by dividing the narrowest dimension by 3.5, i.e. if the narrowest dimension is 350mm divided by 3.5 = 100mm pitch between ball centers. This ensures 3 ball units are always beneath the narrowest dimension of the load at any one time. Load layoutThe weight of the article to be conveyed should be divided by 3. The result will give the maximum load any single ball will bear. On any accurately leveled or flexible sur-face, a number greater than 3 may be used. The surface hardness and condition of the article should be considered to avoid ball unit penetration.
