Abstract
A rolling bearing unit for a swing arm comprises a pivot, a pair of rolling bearings for rotatably supporting the pivot with respect to a stationary shaft, and an E block for the swing arm connected to the pivot, the E block having ends at least one of which is provided with an axially extending lip section, and the lip section being bent e.g. at three locations to be crimped against the end of the pivot for connection.

A rolling bearing unit comprising a pivot having an end, a rolling bearing for rotatably supporting the pivot with respect to a stationary shaft, and an E block connected to the pivot, the E block having ends at least one of which is provided with an axially extending lip section, and the lip section being bent at at least three locations to be crimped against the end of the pivot for connection.
A rolling bearing unit comprising a rolling bearing to be mounted onto a shaft, and a rotating member having a hole formed by way of a pressing process, such that the rolling bearing is fitted into the hole to rotatably support the rotating member with respect to the shaft through the rolling bearing.
A rolling bearing unit for use between a swing arm and a shaft, comprising a pair of rolling bearings each having an outer race and fixed to the shaft under a preload in the axial direction, the swing arm having an inner periphery and the pair of rolling bearings fixed directly to the inner periphery of the swing arm, the outer races of the pair of rolling bearings being fixed to each other under the preload in the axial direction on the pair of the rolling bearings.
A rolling bearing unit for use between a swing arm and a shaft, comprising a pair of rolling bearings each having an outer race and a spacer provided between the outer races, and the pair of rolling bearings fixed to the shaft under a preload in the axial direction, the swing arm having an inner periphery and the pair of rolling bearings and the spacers fixed directly to the inner periphery of the swing arm, the spacer being fixed to at least one of the outer races under the preload in the axial direction on the pair of the rolling bearings.
