igus xiros ball transfer units

Users rely on ball tables for transducers in roller conveyors and for the transport of sensitive goods. To protect both conveyed goods and people from uncontrolled static electricity discharge, igus has developed the tribo-polymer xirodur F182 for its ball transfer units. The material is durable and can move loads up to 500 N smoothly and in all directions without any lubricant.

The ball transfer units are chiefly used in ball tables to move sensitive or heavy loads. A smooth and lubrication-free transport is possible by the use of abrasion-resistant and durable tribo-polymers. It offers an advantage over metallic ball transfer units, which have an insulating effect by the use of lubricant. Such electrostatically dissipative components are required especially in the computer and semiconductor industries, because a surge of electrostatic charge not dissipated by an insulating material can easily destroy the product.

In laboratory testing, xirodur F182 had a surface resistance of less than 105 Ω and is therefore classified in the conductive category according to DIN EN 61340-5-1. As a result, when using the polymer ball transfer units, the user can be sure that puncture voltages are not discharged onto the transported goods or the employees.
