2313K Self-Aligning Ball Bearing For Industrial & Mining Machinery

In the complex machinery landscape, the 2313K bearing is a high - performance component that significantly impacts equipment operation. As a type of self - aligning roller bearing, it is designed to meet the needs of various industrial applications, providing reliable support and smooth motion transmission.

I. Key Dimensions and Specifications

The 65 - mm inner diameter of the 2313K bearing is precisely crafted to fit shafts of corresponding sizes. This accurate fit is crucial for minimizing any play or misalignment during operation, ensuring seamless power transfer and reducing energy losses at the shaft - bearing interface. The 140 - mm outer diameter strikes a balance between load - carrying capacity and space requirements. Despite its relatively compact size, it can effectively distribute radial and axial loads, guaranteeing reliable performance even in harsh operating conditions. The 48 - mm width provides an optimal internal volume for the rolling elements and cage to function smoothly, contributing to the overall stability and reliability of the bearing's operation. The 2.1 - mm fillet radius is designed to reduce stress concentrations at the edges of the bearing, enhancing its fatigue resistance and extending its service life.

II. Ingenious Structural Design

The 2313K bearing features a unique structural configuration. It has an inner ring, an outer ring, and two rows of spherical roller elements. The outer ring has a spherical raceway, which allows the bearing to self - align to compensate for shaft misalignment or housing deflection. This self - aligning ability is a significant advantage, as it helps to reduce stress on the bearing components and improves the overall performance and lifespan of the bearing. The spherical rollers are guided by a cage, which is typically made of steel or brass. The cage plays a crucial role in keeping the rollers evenly spaced and properly aligned, preventing them from colliding with each other. This not only enhances the smoothness of the bearing's rotation but also significantly reduces wear and tear on the rolling elements, thereby extending the bearing's service life. The cage also helps to retain the lubricant within the bearing, ensuring proper lubrication of the rolling elements and reducing friction.

III. High - Quality Material Selection

The 2313K bearing is constructed using high - grade materials to ensure long - lasting performance. The inner and outer rings are typically made of high - carbon chromium bearing steel, which has undergone rigorous heat treatment processes. This results in a material with high hardness, enabling the bearing to withstand substantial radial and axial loads without deformation. The high strength of the bearing steel also ensures that the bearing can endure the stresses associated with high - speed rotation and heavy - duty applications. Additionally, the bearing steel exhibits excellent wear resistance, which is crucial for extending the bearing's service life, as it reduces the rate at which the surfaces of the bearing components wear down over time. The rolling elements are also made of high - quality bearing steel, and their spherical shape is precisely machined to ensure smooth rolling and efficient load distribution. The cage, whether made of steel or brass, offers good strength and durability. Steel cages provide high strength and can withstand high - speed operation, while brass cages offer good corrosion resistance and low friction, making them suitable for use in a variety of operating environments.

IV. Exceptional Performance Highlights

1. High Load - Carrying Capacity

The 2313K bearing is designed to handle significant radial and axial loads. With a dynamic load rating of 97000 N and a static load rating of 32500 N, it can support heavy - duty applications. In industrial machinery such as large - scale conveyors or mining equipment, the 2313K bearing can effectively bear the high loads generated during operation. This ensures that the equipment runs smoothly and reliably, reducing the risk of mechanical failures due to overloading. By efficiently transmitting the loads, the bearing contributes to the overall stability and productivity of the machinery.

2. Self - Aligning Capability

One of the most remarkable features of the 2313K bearing is its self - aligning ability. The spherical raceway of the outer ring allows the bearing to automatically adjust to shaft misalignment or housing deflection within a certain range. This is particularly beneficial in applications where perfect alignment is difficult to achieve or maintain, such as in long - shaft systems or in equipment that is subject to vibrations or thermal expansion. In paper - making machines, for example, the 2313K bearing can compensate for any misalignment in the roll shafts, ensuring smooth paper feeding and consistent paper quality. The self - aligning function helps to reduce stress on the bearing and other components, extending the service life of the entire system.

3. Good Vibration Damping

The 2313K bearing also exhibits excellent vibration - damping properties. The spherical rollers and the self - aligning structure work together to absorb and dissipate vibrations generated during operation. This makes it suitable for applications where reducing vibration and noise is crucial, such as in precision machinery or in equipment used in sensitive environments. In medical imaging devices, the 2313K bearing can help to minimize vibrations, ensuring clear and accurate imaging results. By reducing vibration, the bearing also improves the comfort of operation for operators and reduces the risk of damage to other components due to excessive vibration.
