Design and Features
As a member of the tapered roller bearing family, the 31312 bearing exhibits the typical design advantages of this type
:
Combined Load Capacity: Its structural design enables it to withstand combined radial and unidirectional axial loads simultaneously. The line contact between the rollers and raceways grants it a higher load-carrying capacity compared to ball bearings of the same size
.Separable Design: This bearing is separable, meaning the inner ring (together with the rollers and cage) and the outer ring can be installed independently. This feature simplifies installation, disassembly, and adjustment of the bearing’s internal clearance, enhancing operational convenience
.Adjustment and Paired Use: Single-row tapered roller bearings like the 31312 typically need to be installed in pairs (e.g., face-to-face or back-to-back configurations). The axial position is adjusted to set the appropriate preload or clearance, ensuring optimal performance and limiting axial displacement of the shaft or housing
