escopic way covers are a protection of the guide ways,  and anything in between the way surfaces like ball screws or electrical wires, against mechanical influences such as chips, chemical coolants, and other machining environment components. escopic way covers are extensible or compressible by the sliding of steel overlapping sections. Our way covers, when properly maintained increase the run time of your machine, and are the best solution when hot oils, coolants, metal chips, and heavy material removal are present in the machining environment, in contrast to a fabric bellows.
