KM series consist of linear guideway unit and ballscrew unit. For saving space, PMI combine
the carriage of linear guideway and nut of ballscrew to a integral Carriage-Nut. The carriagenut cooperate with the U rail designed for high rigidity to achieve the high rigidity and high
accuracy in the minimal space, especially to saving time of installation. Moreover, the design of
two rows with Gothic-arch groove and contact angle of 45°can bear four directional loading.
Four Directional Equal Load
KM series are applied two rows with Gothic-arch
groove and designed to contact angle of 45°
which enables it to carry an equal load in radial,
reversed radial and lateral directions to suit to
any mounting orientation.
Combine the carriage of linear guideway and nut of ballscrew to a carriage-nut, KM series can
achieve the best use of space.
Base on the optimal analysis of FEM for the shape of U rail, it has the balance between light
weight and high ridigity.
The design of two rows with Gothic-arch groove and stable manufacturing technology can control the variation by load at the minimum. It can provide the smooth feed with high
