Abstract
The invention relates to a tubular home-automation actuator for driving a winding tube (310), said actuator comprising a head system (100) including a fixed point (1), a bush bearing (2), and a head (3A; 3B). The fixed point (1) forms a bearing surface (11) for guiding the bush bearing (2) in rotation, said bush bearing (2) partially covering a tube (210) of the tubular home-automation actuator. The head (3A, 3B) comprises a bore (32) having a first connecting element (33) that engages with a second connecting element (13) provided on the outer periphery of the fixed point (1) such as to connect the head and the fixed point in a rotatable manner. The head comprises a stop element (31) serving as an axial stop to the bush bearing along the longitudinal axis when the head is mounted on the fixed point.
