###### Abstract
A study on the performance of multirecess conical hybrid journal bearings with orifice restrictors subjected to wear indicated that wear reduces the load capacity while the restrictors provided some performance improvement [7]. [PERSON] et al. investigated the compounding effects of wear on three-lobe three-pocket misaligned hybrid journal bearings with capillary restrictors [8]. They found that wear and misalignments cause deterioration of the performance of the bearings, but the capillary restrictors reduce the effects of the wear and misalignment. [PERSON] et al. demonstrated in [9] that wear produced during the running-in phase plays a role in stabilizing edge loading as well as improving journal bearing performance in the long term. [PERSON] et al. [10] developed a model that couples the transient mixed lubrication and wear. Their model highlights the dynamic evolution of wear profiles and influence of lubrication performance. These studies demonstrate the effect of wear on the performance of journal bearings. There have also been numerous studies, both experimental and numerical, that seek to enhance our knowledge of wear of journal bearings. The studies have sought to address a variety of topics, including the effect of wear on the thermo-hydrodynamic performance of the bearings [1,2], tribological performance of lubricated bearings [4, 5, 6, 7, 8, 9, 10, 11, 12], the relation between journal bearing wear and shaft misalignment [3], and wear prediction in journal

Undoubtedly, there are numerous aspects of wear in journal bearings that still need to be investigated. Among these is the effect of journal bearing geometry on the wear of journal bearings. The author was unable to find any studies addressing this matter. This article thus seeks to fill this gap in the literature. The objective of this article is to examine the impact of journal bearing geometry on wear. The journal bearing is assumed to operate under dry contact conditions, utilizing prediction methods commonly applied in studies on wear in dry contact applications. Various previous studies have explored similar dry contact scenarios, such as brake disk and brake pad wear. For instance, [PERSON] et al. [18] developed a finite element analysis (FEA)-based methodology to predict disk brake wear. Their wear prediction procedure, based on [PERSON]'s wear model, involves mapping wear rates as functions of local contact pressure and sliding speed, which are then used as inputs in the FEA model. The contact behavior between the rotor and brake pads is simulated during a braking event, with iterative surface updates to account for progressive wear. Similarly, [PERSON] et al. [19] presented an FEA numerical simulation approach for predicting disk brake wear. They employed a modified version of [PERSON]'s wear formula to estimate wear over specific braking periods. To validate their finite element model, they conducted static contact pressure distribution experiments using pressure-sensitive films. Their findings indicated that contact areas expanded as wear progressed, leading them to conclude that incorporating wear effects into FEA enables more accurate predictions of friction material wear behavior. Additionally, [PERSON] et al. [20] introduced an FEA approach for predicting wear and contact pressure distribution in disk brakes, also based on [PERSON]'s wear law. Their study further reinforces the effectiveness of FEA in modeling and understanding wear behavior in dry contact applications. For this study, wear prediction procedures based on the EFM and FEM methods are presented followed by procedures on wear analysis on journal bearings in a multibody dynamic setting (specifically a slider-crank mechanism). Wear on 35 different dimensional configurations for a journal bearing in a slider crank mechanism are conducted to facilitate the study.
