In this paper, properties such as friction and wear that occur during the operation between the rollers and rail in the automatic cabin door and landing door mechanisms of elevators were studied. Smooth and failure-free operation of the rails and rollers in the floor and cabin door opening and closing mechanisms, which are integral components of elevator systems, is crucial for ensuring safety and comfort. Although elevator floor and car door mechanism rails vary according to the operating system, they generally operate in dry and/or boundary friction conditions. Under these friction conditions, wear is inevitable. In the literature, the study of the tribological properties of materials such as rail, brake, and roller is usually done with model test rigs such as Pin on Disc or Reciprocating wear test systems. Two types of presented test systems were used in the study. First, a test model with an elevator car door opening and closing system designed and produced with the suggestions and support of the manufacturers within the scope of the project (Durak, 2023), and secondly, the reciprocating wear test rig were used. Galvanized coated rail and AFC (Dry/Slippery Film Lubricating Coating) technology, which is widely used in the market, were used as test specimens. The friction coefficients and wear amounts of the samples were determined experimentally and the test results obtained were interpreted. In addition, damage cases were observed on both the roller and the rails. It is expected that the findings will greatly contribute to the development of literature, rail, and roller materials for elevator and elevator element manufacturers.
