Linear ball bearings

Linear ball bearings are become standard in dodays technology. They provide precise and fast element movement with minimal abrasion. Easy assembly and long working life are there main characteristic. It has application with CNC cross tables, manipulators, and many machines that need automatic feed such as wood working machines, plastic industy etc. They come in tree different types of witch two are mainly used.

Linear ball bearing closed type LM_UU is mainly in use. It is used with linear systems on shafts witch are fixed at the ends. Mounting on holes made in H accuracy, and its blocked with snapring.

Linear ball bearing clossed type are used in linear systems on shafts with footage (hole lenght or partial). Mounting on holes made in H accuracy, and its blocked with snapring(internal or external)
