The roller energy chain has been the tried-and-tested energy supply for long travels for about 20 years. Besides the successful design that distinguishes all of our linear energy chain systems, stainless steel rollers are added, which upgrade the energy chain to energy supply for heavy-duty applications. As the energy chain rolls and does not glide, it runs quietly and with low vibration. Wear is significantly lower than for designs without rollers, and the power needed for movement is also lower by as much as 57%.
