cylindrical rollers can be used in joint bearings, which are a type of plain bearing designed to accommodate both radial and axial loads. Joint bearings, also known as spherical plain bearings or plain spherical bearings, typically consist of an inner ring, an outer ring, and a sliding layer between them, which may include cylindrical rollers or other types of rolling elements.

joint bearings with cylindrical rollers can be used in a wide range of applications, including construction equipment, mining machinery, and heavy-duty transportation, where they can provide high load-bearing capacity and long service life. However, the selection of the right type of joint bearing depends on several factors, such as the load conditions, the speed of operation, and the environmental conditions, and requires careful consideration of the specific application requirements.
