Title:
SUPPORTER FOR CARRIAGE
Document Type and Number:
Japanese Patent JPS59196137
Kind Code:
A
Abstract:
A bearing arrangement for guiding a carriage in a straight line along a guide rail has four endless courses of balls disposed between the guide rail and the carriage, and the guide rail is provided with four parallel ball races associated with the load-bearing balls of the ball courses. The balls are held in elongated ball bearing assemblies. The ball races are located in the respective transitional zones between two adjacent shanks, located one above the other, of the substantially double-T-shaped or cruciform guide rail. In order to increase the flexural strength of the guide rail and to provide a manner of securing it in a tilt-free manner, the arrangment is selected such that on at least one side the guide rail has two integral, longitudinal parallel ribs, which define a longitudinal groove in which securing devices for the guide rail and/or for elements insertable into the longitudinal groove are disposed, fitting seats between the ball bearing assemblies and the carriage insure accurate guidance.
