The invention is a mounting assembly for a roller that includes a bearing and a fastener. The fastener is at least partially shrouded by a sleeve, the end of which is keyed into the roller. The use of the sleeve provides an additional bearing surface to allow the roller to rotate with the bearing. However, should the bearing seize, the sleeve, and therefore the roller, is still able to rotate without affecting the fastener. This means that the fastener does not unravel and disengage from the housing. The invention has particular application to the mounting of rollers to the mower deck of a mowing implement although this is not meant to be limiting and the invention may be used with many types of apparatus requiring rollers.
