Design and Performance Characteristics
The performance characteristics of the UK207 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, thereby reducing wear and vibration
.Ready-to-Install and Sealing: This type of bearing is typically equipped with seals on both sides, which effectively prevent the ingress of contaminants. Furthermore, it is pre-lubricated from the factory, enabling a "ready-to-install" approach that greatly simplifies the maintenance process
. Its fixing methods include set screws, eccentric collars, or adapter sleeves for convenient and secure fastening directly onto solid shafts.Load Characteristics and Considerations: This bearing is primarily designed to withstand combined radial and axial loads, where the radial load is dominant. It is important to note that it is generally not suitable for carrying axial load alone. For models locked with set screws, the allowable axial load must not exceed 20% of its dynamic load rating
