Linear ball bearing B series

steel

BOLEXP ball guidance bushes are made up of an outer casing of steel for rolling, hardened and ground, which holds fixed inside a high-resistance bronze cage for guiding the balls running along the cage. The translation system consists of several rows of precision balls circulating endlessly. The great novelty of our system is that balls do not run aligned, with the translation motion, but at a slight angle, thus enlarging the contact area with the shaft and enabling greater load capacity. This system represented an utter innovation in the linear guidance market. An all-metal structure makes bushes extremely resistant to high temperatures. BOLEXP bushes are supplied in a variety of three outer forms, all of them equipped with the same inside structure. Completing the guidance set, the BOLEXP pillar is made of steel with surface hardening, leaving the shaft core soft so that it can absorb the bending it might be required to.
