The conveyor roller comprises a tubular shell defining a longitudinal axis, a hub and an intermediate ring between the hub and the shell. The hub comprises a shaft member aligned with the longitudinal axis, a bearing support member and a bearing member having an inner race attached to the shaft member and an outer race attached to the bearing support member for allowing relative rotation of the shaft member and the bearing support member. A first releasable attachment member releasably attaches the intermediate ring to the bearing support member and a second releasable attachment member releasably attaches the intermediate ring to the tubular shell. |
