1. A sprinkler assembly comprising:
an inlet configured to receive water;
a bracket supported by the inlet;
a nozzle in fluid communication with the inlet and positioned downstream of the inlet, the nozzle being configured to direct the water out of the nozzle along an axis;
a bearing positioned downstream of the nozzle and supported by the bracket;
a deflector assembly disposed between the nozzle and the bearing and supported by the bearing at least when the sprinkler assembly is not pressurized, the deflector assembly being configured to move with respect to the axis in one or both of a rotational and a tilting direction, the deflector assembly comprising:
a distribution plate positioned downstream of the nozzle and configured to deflect water from the nozzle,
a spindle extending from a side of the distribution plate facing away from the nozzle and at least to the bearing,
a wear sleeve carried by the spindle and positioned downstream of the distribution plate, and
a weight carried by the spindle and having a mass selected to adjust or change a rotational speed of the distribution plate; and
a housing supported by the bracket and at least partially surrounding the wear sleeve, the housing having one or more surfaces configured to contact the wear sleeve so as to limit movement of the deflector assembly in one or both of the rotational and the tilting direction about the housing when the sprinkler assembly is pressurized,
wherein the spindle extends further downstream than the weight, and wherein the bearing is disposed so that a horizontal plane passes through both a portion of the bearing and a portion of the wear sleeve.
