Performance Characteristics
The performance characteristics of the 31303 bearing stem from the fundamental design of tapered roller bearings
.
Combined Load Capacity: Its design enables it to withstand combined radial loads(force perpendicular to the axis) and unidirectional axial loads(force along the axis) simultaneously. It is particularly suitable for applications involving combined loads where the radial load is predominant, offering a high 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
.Process and Material: The bearing is typically made of high-carbon chromium bearing steel (GCr15), which provides a high hardness (e.g., 59-62 HRC). The cage is generally a pressed steel cage, ensuring the bearing's durability and long service life
