They are suitable for goods to be conveyed with a smooth and load-bearing underside. Due to their very low frictional resistance, they reduce the amount of work and effort required for unit load handling and enable transport in all directions. Ball cup rollers are attached and secured to a carrier plate with clips, flanged ball rollers are attached by means of rivets or screws.
The ball transfer unit consists of the load ball and a number of small supporting balls mounted in a shell. This design allows the load ball to rotate with low friction in all directions. Heavy loads can be easily moved without much effort.
