Product description

Ball transfer units GN 509 are used, for example, in conveyor technology or on packing tables to move heavy loads in any direction without great effort. The roller bearing of the ball and the felt ring for dust protection ensure reliable operation and a long service life.

The diameter d₂ features a taper in the upper area, beneath the flange, which allows it to be easily and firmly installed.

When determining the size of the ball transfer units, it is necessary to consider not only the weight but also the size and nature of the base area of the load. The maximum distance between the ball transfer units „a₂“ (assuming a flat base area) is calculated by dividing the shortest edge length of the load by 2.5. This ensures that the load always rests on the ball transfer units, preventing it from tipping over into the spaces between them. The required load capacity of the ball transfer units is calculated by dividing the weight of the load by 3. This results from the assumption that, due to tolerances of the load base area and the ball transfer units, only three ball transfer units are normally used.

a₁ = Shortest edge length of the load a₂ = Max. distance between ball transfer units a₂ = a₁/2.5						F₁ = Load weight F₂ = Load per ball transfer unit F₂ = F₁/3
