Crossed roller guide rail
KOYO
motion bearing unit consisting of two raceway
bases. Each base has one longitudinal plane eut
into a V shape, which serves as the rolling
surface. Two bases are in contact on each ot the
other"s V-cut surface, and cylindrical rollers with
a retainer are placed between the surfaces. Any
pair of adjacent cylindrical rollers is directed at
right angles to each other, thus enabling smooth
and extremely accurate linear motion.
