Abstract:
A bearing device has a sleeve that encircles a shaft, and two side-by-side roller bearings rotatably support the sleeve coaxially on the shaft. A spacer portion protrudes radially inwardly from the sleeve and extends between the two roller bearings. The sleeve axially overlaps a minor portion of one roller bearing but does not overlap a race surface thereof, and the sleeve axially overlaps a major portion of the other roller bearing including a race surface thereof.
