Bearing-holder support for rotating elements

摘要

Bearing-holder support (21) for rotating elements, the bearing-holder support (21) being suitable forbeing engaged by a shaft (11), and being provided with two rolling contact bearings (23a) (23b), and atubular plastic tube (22) which extends along a longitudinal axis A of the motor shaft and presents two inner annular housings (25a)(25b) for housing the two bearings (23a) (23b); the plastic tube (22) being made up of two modular semitubes (22a) (22b), each of which presents a relative annular housing (25a) (25b) which is obtained by co-moulding of the modular portion itself with a relative bearing (23a) (23b) in order to axially block the bearing (23a) (23b) itself inside the annular housing (25a) (25b) itself.
