In bottle filling machines, the complex sequence of movements of the star wheel transfer units is achieved mechanically via cam plate controllers. Stud type track rollers are essential for this. Stud type track rollers with Triondur® coating on the outer surface are also used to prevent wear on the mating track. This coating offers durable protection in cases of high tribomechanical stresses, lubricant starvation and dry running.

Monorail guidance systems KUVE are used as the precise and low-friction bearing supports of the distributors.
