ABSTRACT:
A hangar bearing is designed to be employed in a drying oven, generally known as a "tunnel" type, which is used to dry plywood, veneer board, fiber, or gypsum board. The hanger bearing main body support is made from a pair of identical stamped forms or fabricated plates which include various matched bores to facilitate both mounting and mutual securement. Each of the main body plates includes a depression that conforms to provide a bearing insert support cavity when the plates are fitted together. The bearing insert support cavity may or may not include anti-rotational flanges and/or longitudinal travel stops to hold the semi-cylindrical bearing insert element in place. A steel retaining loop or strap is provided to overarch the bearing element, once it is in place, the loop or strap being preferably provided with a hinge and a releasable retaining clip. The semi-cylindrical bearing insert element supports the rotating journal or shaft of the conveyor rollers and the strap or loop prevents the shaft from being displaced due to axial vibration. The novel construction of the integrated hanger bearing allows for modular replacement of various parts of the device due to high temperature wear.
