NB Linear System

NB Linear SystemIndustrial machinery is prevalent among many different fields of industry. Linear motion is one of the basic mechanisms that design in the machinery. Linear motion utilizes sliding and rolling motions to transfer power and displacement into guiding linear-movement.
This mechanism is considered to be one of the most important factors in every industrial field.

NB Linear Systems are bearings that utilize the rotational motion of ball and roller elements. The dynamic friction of the ball or roller is substantially lower than that of full-face surface sliding bearings. NB linear systems achieve smooth movement and precise motion response in terms of positioning accuracy by the rolling elements and precision-ground raceway surface.
The NB linear system uses relatively large rolling elements on a long raceway resulting in a high load capacity and long travel life.

Nippon Bearing Co., Ltd, as a general linear bearings manufacturer, contributes to industrial fields not only in Japan but also around the world.
