Lubrication-free ball transfer units with up to 500N capacityigus is introducing advanced polymer ball transfer units for use on ball tables to ensure five times more load-bearing capacity. These conveyor tables transport delicate or heavy goods in multiple directions. Made of the high-performance plastic xirodur B180, the ball transfer units can support loads of up to 500N. Stainless steel balls inside the roller allow smooth running.

Ball tables are used wherever sensitive or heavy loads are transported from A to B: items such as circuit boards, food, goods in airports, glass panes or goods in the sheet metal processing industry. By using ball transfer units in the conveyor tables, loads can be transferred quickly and easily in any direction.

Being dimensionally identical to metallic ball transfer units is where the similarity ends, all igus units are lubrication-free and maintenance-free, ensuring no lubricating grease can adhere to the goods. By using a plastic ball, these rollers are suitable for transporting delicate goods in the food and drinks industry. Another advantage compared with metal: the ball transfer units can be used in any installation position, whether horizontal, vertical or overhead, which now also extends the field of application to the furniture industry.

The new polymer ball transfer units have an optimised housing interior, so they can now take up to five times more load than before. They are currently available in three installation sizes and, depending on their size, withstand an axial load of 150 to 500N. The xirodur B180 material is very abrasion-resistant, has a long service life and an electrically insulating effect.

The rollers are mounted by simply pressing into the housing. If the engineer wants to additionally secure the polymer ball transfer unit, a special clamping ring is available for extra security. Glass balls are also available for metal-free and therefore non-magnetic applications.
