Abstract
A bearing wear guard includes a slotted body portion cast from a wear-resistant metal. The slots receive two bearing mounting bolts which secure the guard in a protecting position in the path of rocks and abrasive debris traveling towards the bearing and bearing support. An upper edge portion conforms generally to the shape of the lower portion of the bearing. The casting includes a grease zerk-protecting area extending upwardly and outwardly from the upper edge portion to protect the zerk from rocks and abrasive material. Leading and trailing trash shedding surfaces on the body portion prevent trash from catching and building up on the guard. The body portion has an L-shaped cross section also providing protection for the bearing mounting bracket.
