Proposed is a design for a molded plastic split shaft bearing that possesses friction and wear qualities similar to those of a regular shaft bearing. As shown in Figure 1, a split shaft bearing 10 has an edge opening 26. A lip 20 functions as a stopper when the bearing 10 is inserted into a receiving member (not shown). The bearing 10 features a ridge 22 that aids in retaining the bearing 10 in the receiving member. In order to alleviate excess material during the fabrication process, the bearing 10 has a honey-comb structure 24. The honeycomb structure 24 provides a uniform wall thickness which minimizes the molding cycle time, and thus fabrication costs.
