ABSTRACT:
A rolling support device or ball roller comprises a main ball housed in a casing comprising a substantially hemispherical bearing bush, an outer shell and a retaining ring assembly connected to the outer shell to retain the main ball and the bearing bush therein with a portion of the ball exposed through the ring to contact a member to be supported thereby; the outer shell is shaped to be received in an opening in a supporting member and the retaining ring defines a shoulder determining the limit of insertion; resilient tongues projecting from the casing act to retain the device in such an opening, for which purpose the tongues have an elbow portion each provided with at least one radially outwardly projecting tooth for biting into the side wall of an opening receiving the device to resist withdrawal thereof.
