Design Features
The performance characteristics of the SB209 bearing stem from its design as an outer spherical ball bearing
.
•
Self-Aligning Capability: The outer diameter surface of the bearing's outer ring is spherical. Thanks to this design, when installed into a bearing housing with a corresponding spherical inner bore, it can automatically align itself to compensate 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, which effectively prevent the ingress of contaminants. Furthermore, it is pre-lubricated with an appropriate amount of grease from the factory, enabling a "ready-to-install" approach that simplifies maintenance
. Some models feature a set screw design for convenient and secure fastening directly onto solid shafts .•
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 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 the dynamic load rating
