Abstract:
A retractable antifriction bearing device (10a) that can be housed in a standardized groove of a loading bed. Each ball (30) is mounted directly in a housing (21a) of the profile (20a) by a guide and sealing ring (50) provided with a spherical cavity (53) that complements the ball (30) to hold the ball in position with respect to the housing (21a). A bearing guide (60a) is also mounted directly in the housing (21a) and is provided with a cup (61) guiding the ball (30) in rotation via a bed of small balls (62). This bearing guide (60a) is spring-loaded by spring elements (40a) so as to urge the ball (30) into the working position in which the ball bears the load (2).
