Design and Performance Characteristics
The performance characteristics of the UD208 bearing stem from its fundamental design as an outer spherical ball bearing
.
Self-Aligning Capability: The outer diameter surface of the bearing's outer ring is spherical. When installed into a bearing housing with a corresponding spherical inner bore, it can automatically align itself, compensating for misalignment caused by installation errors, shaft deflection, or machining inaccuracies
.Ready-to-Install and Sealing: This type of bearing is typically equipped with seals on both sides (2RS), which effectively prevent the ingress of contaminants. Furthermore, it is pre-lubricated from the factory, enabling a "ready-to-install" approach that simplifies the maintenance process
.Load Characteristics: This bearing is primarily designed to withstand combined radial and axial loads, where the radial load is dominant. It is important to note that the allowable axial load generally should not exceed 20% of its dynamic load rating
