Load rollers; load capacity

The maximum load capacity van a load roller is determined by:
- bearing cases (side A + B);
- the tube and spindle diameter;
- the spindle type;
- the partial length under load;
- the load pattern (evenly distributed or point load).

The weight of the product to be transported must not be greater than the total load capacity of the load-bearing rollers. If the product or its packaging have hard, stiff and irregular contact surfaces, a situation may occur in which the rollers directly beneath the product are not taking the whole weight. This can mean that only two or three rollers may be carrying the total weight of the product. In practice this may lead to more rollers having to be placed than calculated theoretically, or that stronger rollers have to be used.
