Ball Guidance
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.
