摘要： A bearing element 100, such as a bearing shell for an engine, has an overlay 106 which forms the bearing surface against a steel journal or the like. The overlay layer 106 is formed from a bearing material comprising a polymer matrix of polyamide-imide polymer material, and solid lubricant particulate. The solid lubricant particulate has a median particle size of less than 1 micrometre. A bearing element 100 comprising the bearing material, and a method of forming the bearing element 100 having the bearing material are also provided.
