Abstract
A linear bearing slide assembly comprises an outer member, an inner member, a pair of linear bearing mechanisms, a preloading bar and a longitudinal spring. The outer member has a primary channel opening for accepting the inner member, and two secondary channel openings for accepting the linear bearing mechanisms and a preloading assembly. The inner member is located in the primary channel opening of the outer member. The first and second linear bearing mechanisms are located in the secondary channels on opposite sides of the primary channel opening. These linear bearing mechanisms support and guide the inner member as it travels along the primary channel opening in the outer member. Each of the linear bearing mechanisms can be conventionally constructed with either sliding or a plurality of rolling elements between two bearing ways. One of the linear bearing mechanism is compressed between the inner member and a preloading bar in the secondary channel by a longitudinal spring typically having a sinusoidal contour. The spring provides a compressive force to the preloading bar to eliminate component play and provide a consistent preload to the linear bearing mechanisms.
