A roller bearing arrangement (100) of a fan shaft (26) for a gas turbine engine (10) includes the fan shaft (26), and a stub shaft (110) connected to the fan shaft (26). The roller bearing arrangement (100) further includes a plurality of roller bearing elements (130) positioned between a first axial bearing surface (118) created on a radially outer surface (114) of the stub shaft (110) and a second axial bearing surface (128) of a static structure (127). The roller bearing arrangement (100) further includes a first snubber (140) positioned between the radially outer surface (50) of the fan shaft (26) and a radially inner surface (112) of the stub shaft (110). The first snubber (140) is spaced apart from the radially inner surface (112) of the stub shaft (110) or the radially outer surface (50) of the fan shaft (26) so as to limit a radial movement range of the stub shaft (110).
