The aim of the paper is to check the load-bearing of batch plates. The batch plates are used for coating process of ball joints in a gas nitriding furnace. The plates have circular shape with two types of circular holes, the first type of holes are used for gas flow and the ones are used for ball joints. The plates are laid on the supporting frame. The frame is supported in four suspension eyes, it is loaded by the actual weight of the plate and the plate is loaded by the weight of the stored ball joints. From the results is clear that adjustments need to be made on the supporting frame for the safe operation.
