Product Features and Main Applications
Self-Aligning Capability: The UD205 is a type of outer spherical ball bearing. Its most critical feature is the spherical outer diameter surface of its outer ring, which allows it to be seated into the corresponding concave spherical surface of the bearing housing. This provides an automatic self-aligning effect, effectively compensating for misalignment caused by installation errors or shaft deflection
.Effective Sealing and Pre-Lubrication: This type of bearing is typically equipped with seals on both sides, providing effective protection against the intrusion of contaminants. It is pre-lubricated with an appropriate amount of lubricant at the factory, generally requiring no cleaning or additional lubrication before installation
. The set screws on the extended end of the inner ring allow for direct fastening onto the shaft, simplifying the installation process. It is important to note that when using this fixation method, the permissible axial load must not exceed 20% of the dynamic load rating .Primary Application Fields: Thanks to its self-aligning performance and effective sealing, the UD205 bearing is well-suited for relatively harsh working environments where alignment requirements are not critical. It is commonly used in applications such as mining machinery, engineering machinery, textile machinery, and agricultural machinery
