Design analysis of bearing units of conveyor rollers

This article discusses various types of bearing seals, including groove, stuffing box, labyrinth and combined, as well as their advantages and disadvantages depending on operating conditions. Various types of rolling bearings are described, such as ball and roller angular contact tapered single row bearings, their features and applications. Special attention is paid to the causes of bearing failure, including fatigue failure and abrasive wear. Methods for calculating the durability of bearings and the influence of dynamic loads on their operation are also considered. The work highlights the importance of an integrated approach to the design and operation of bearing units to improve the reliability and efficiency of conveyor systems.
