Abstract: An improved tool-holder fixture, more specifically for tool holders, pincer holders and mill holders, designed for the mounting and dismounting thereof, which comprises a cage body (1) constituting the main support body for a needle bearing (2), a cover (3), a roller cage (4), rollers (5), a top cover (6) and screws (7) for fastening same.

Abstract: An improved tool-holder fixture, more specifically for tool holders, pincer holders and mill holders, designed for the mounting and dismounting thereof, which comprises a cage body (1) constituting the main support body for a needle bearing (2), a cover (3), a roller cage (4), rollers (5), a top cover (6) and screws (7) for fastening same. The cage body (1) comprises a stepped through-hole within which the needle bearing (2) and the cover (3) are housed, while the cage (4) is received in the interior of the hole and on top of the needle bearing (2) and the cover (3), the latter two components facilitating the smooth rotation of said part, the rollers (5) being suitable to be received in the cavities defined between the cage (4) and the cage body (1), the latter element having, machined therein, plural half-moon-shaped cavities that serve as ramps for the rollers (5), the top cover (6) being disposed in the upper portion of the unit and being fastened directly to the cage body (1) by means of the screws (7).
