Abstract
A roller bearing unit includes a shaft having a stepped part along a longitudinal axis; a first conical roller bearing which abuts the stepped part; a spacer that abuts, from a side opposite the stepped part, a first outer ring of the first conical roller bearing; a second conical roller bearing having a second outer ring that sandwiches the spacer between the first outer ring and the second outer ring, and a pressing member that is attached to the shaft and presses the first inner ring and the second inner ring in a direction to cause the first inner ring and the second inner ring to approach each other. A recess is recessed in a radial direction in an outer surface of the spacer to enable an external force along the longitudinal axis direction to be applied to the first outer ring from the spacer side.
