Freedom from lubrication and maintenance are decisive arguments for efficient material handling in overhead conveyor technology. A smooth warehousing process is based on resilient components. xiros ball bearings are ideal for the specific requirements of the industry and its various branches. The flexible and lightweight plastic ball bearings, which require little installation space, offer a wide range of potential applications (chain conveyors, power and free conveyors, circular conveyors or pocket sorters). In overhead conveyor systems, xiros ball bearings can be used as skate wheels, which can be adapted to the respective roller carrier system. In this way, laundries, for example, can realise weights of up to 5kg/extender crossbar and speeds of up to 1,000rpm. They can therefore use the lubrication-free plastic for safe, clean and sustainable transport. Higher loads are no problem for other applications.
