Design and Performance Characteristics
The performance characteristics of the 31307 bearing stem from the fundamental design of tapered roller bearings
.
Combined Load Capacity: The tapered roller design enables the bearing to withstand combined radial loads(force perpendicular to the axis) and unidirectional axial loads(force along the axis) simultaneously, resulting in a high combined load-carrying capacity
.Separable Design: The bearing features a separable design, meaning the inner ring (including the rollers and cage) and the outer ring can be mounted separately
. This characteristic simplifies the installation and disassembly processes. Furthermore, it allows for the adjustment of the bearing's internal clearance after installation, which is crucial for optimizing system rigidity and controlling running accuracy .Material and Process: The bearing is typically manufactured from high-carbon chromium bearing steel (GCr15), and the cage is generally a pressed steel cage, ensuring the bearing's durability and long service life
