In some bearing applications, such as planetary gear, rolling mills, and airplanes, the flexibility of bearing rings is crucial for determining the properties of the such metal component. That is why quality seamless rolled rings are important.
When a heavy applied load, a big-size bearing, a hollow shaft, and a nonrigid bearing housing are present, it may significantly alter the dynamics, characteristics, bearing deflections, contact stresses, and fatigue endurance.
Types of Bearings
Cylindrical Roller Bearings
Line contact between the rolling components and the raceways in cylindrical roller bearings optimizes the distribution of stress factors at the point of contact. Because of this configuration, cylindrical roller bearings have an extremely high radial load rating.
Spherical Roller Bearings
With the difference that they use spherical rollers rather than ball rollers, this type of bearing is exceptionally durable and can operate on the same principles as self-aligning bearings. Such characteristic enables them to sustain higher loads. Misalignments between the shaft and the housing may be corrected by doing this.
Line contact is a known characteristic of roller bearings. It has a better load capacity than ball bearings of the same size, but because of the increased friction of a contact line, it has a lower speed capability.
Self-Aligning Ball Bearings
Self-aligning ball bearings contain a continuous spherical outer ring racetrack that enables the inner ring/ball complement to revolve within the outer ring in addition to a double row of balls led by a cage and a double row inner ring raceway. This makes it possible for the application to self-align to some extent.
Process of Making Seamless Rolled Rings
The first step in the production of a bearing is the processing of the blank bearing. The productivity level and the quality of the blank ring will significantly impact an organization’s performance, longevity, and financial success.
The internal quality of the ring, including the density of material, metal fiber streamline distribution, grain size, and deformation heat treatment, will have a greater impact on the bearing’s life. The reason for this is that the size of the blank quality (including the blank forming method) will determine the bearing material utilization.
Get Quality Seamless Rolled Rings
The major causes of rejection rates are blank size dispersion and geometry accuracy, inability of automated manufacturing, and the impact of subsequent process processing quality (error copy). The quality of the blank is determined by ring rolling equipment precision and performance. Moreover, the quality of turning will influence the precision and efficiency of grinding and the bearing blank will influence turning and machining accuracy.
