Document Type and Number:
WIPO Patent Application WO/2021/045232
Kind Code:
A1
Abstract:
[Problem] To provide a method whereby pre-loading applied to a rolling element can be more precisely managed. [Solution] An inner ring (13) is fitted onto a fitting cylindrical part (17) of a hub ring (14), and the axial gap decrease ∆C of a hub unit bearing (1) is derived on the basis of the inner-ring expansion ∆D, which is the difference between the outside diameter dimension (D1) of the inner ring (13) after a crimped part (19) is formed and the outside diameter dimension (D0) of the inner ring (13) before the inner ring (13) is fitted onto the fitting cylindrical part (17).
