The invention relates to a hub for an unducted propeller (14) having variable-pitch blades (18) of a turbine engine, comprising two parallel annular side walls (34) between which are arranged rings (36) which are distributed angularly in a regular manner around a longitudinal axis (A) of the hub, which are connected to the annular side walls (34), and which comprise compartments (26) receiving bearings (32) having radial axes (R) for guiding in rotation roots (30) of blades of said propeller, said rings (36) being connected in pairs by connection means (40) which are arranged between the annular side walls (34) and which comprise substantially radial reinforcing partitions (42, 44, 46), characterised in that at least some of said reinforcing partitions (42, 44, 46) are connected to said annular side walls (34).
