The present invention relates to a bearing arrangement (104) connectable to a shaft (102), the bearing arrangement comprising a bearing (105, 105′) comprising a plurality of rolling elements (110) arranged to rotate relative to an inner raceway (302) for said bearing arrangement; and a ring shaped contact element (114, 114′) having an extension in an axial direction thereof, the ring shaped contact element further comprising a first contact surface (402) adapted to face the plurality of rolling elements, wherein an inner diameter of the ring shaped contact element at the axial position of the first contact surface has a larger diameter in comparison to a diameter (412) of the inner raceway, such that a continuous radial gap (414) is provided in the circumferential direction between the ring shaped contact element and the inner raceway when the bearing arrangement is connected to the shaft, wherein the radial gap (414) is arranged to be provided in fluid communication with a lubricating flow channel (306) of the shaft when the bearing arrangement.
A bearing arrangement (104) connectable to a shaft (102), the bearing arrangement (104) comprising:
An assembly (100) comprising:
A ring shaped contact element (114, 114′) connectable to a shaft (102) provided with a bearing (105, 105′) comprising a plurality of rolling elements (110) arranged to rotate relative to said shaft (102) around an inner raceway (302), said ring shaped contact element (114, 114′) has an extension in an axial direction thereof and comprises a shaft connecting portion (408) arranged to be connected to the shaft (102), and a first contact surface (402) adapted to face the plurality of rolling elements (110), wherein an inner diameter (410) of the ring shaped contact element (114, 114′) at the axial position of the first contact surface (402) has a diameter which is arranged to be larger in comparison to a diameter (412) of said inner raceway (302) for providing a continuous radial gap (414) in the circumferential direction between the ring shaped contact element (114, 114′) and the inner raceway (302) when the ring shaped contact element (114, 114′) is connected to the shaft (102), wherein the ring shaped contact element (114, 114′) is arranged to be connected to the shaft in such a way that said radial gap (414) is provided in fluid communication with a lubricating flow channel (306) of the shaft (102).
