29420 E 100X210X67mm Spherical roller thrust bearing

Spherical roller thrust bearings accommodate very heavy axial and considerable radial loads. They have the highest load rating of all thrust bearings, enabling compact, high power density bearing arrangements. By combining two or more spherical roller thrust bearings, it is possible to create a bearing arrangement that is either self-aligning, allowing misalignment of the shaft, or very stiff.

The 29420 E is a spherical roller thrust bearing, specifically designed to accommodate heavy axial loads while providing excellent performance and durability. Below is a detailed explanation of its features, design specifications, and applications.

Overview of the 29420 E Spherical Roller Thrust Bearing
1. Design and Construction
Thrust Bearing Type: The 29420 E is categorized as a spherical roller thrust bearing, which is designed to support axial loads and allow for a certain degree of misalignment between components.
Rolling Elements: The bearing features spherical rollers that can tilt slightly in their raceway, which allows it to compensate for misalignment and provides stability in operation.
Raceways: The bearing has two main raceways: an inner raceway for the shaft and an outer raceway that accommodates the spherical rollers. This design helps distribute the load evenly across the bearing.
Cage Design: A robust cage (or retainer) is often employed to keep the rollers spaced evenly and reduce friction, allowing for smooth rotation and minimizing wear.
2. Specifications
Dimensions:
Outer Diameter (D): 210 mm
Inner Diameter (d): 100 mm
Width (B): 67 mm
Load Ratings:
Dynamic Load Rating (C): Specific to the manufacturer, but generally rated for substantial axial loads.
Static Load Rating (C0): Also substantial, designed to withstand high static loads without deformation.
Operating Temperature Range: Typically suitable for a range of operating temperatures, but specific limits depend on lubrication and application conditions.
3. Applications
Heavy Machinery: Commonly used in applications that require the support of high axial loads, such as the thrust bearings in cranes, excavators, and other heavy machinery.
Marine Applications: Often found in marine equipment, where they provide thrust support in marine engines and propulsion systems.
Power Generation: Used in turbine generators and other equipment in power plants where axial loads are prevalent.
Mining Industry: Frequently utilized in mining equipment to handle the significant forces involved in drilling and processing.
4. Advantages
High Load Capacity: The spherical rolling elements enable the bearing to support high axial loads while maintaining stable operation.
Self-Aligning Capability: The design accommodates misalignment, which helps prevent premature wear and failure.
Durability and Longevity: Constructed from high-quality materials, these bearings are designed for long service life, even in harsh operating conditions.
5. Installation and Maintenance
Installation: Proper installation procedures are important to ensure optimal performance. Care must be taken to align the bearing correctly and securely fasten it to the housing.
Lubrication: Regular lubrication is critical for minimizing friction and wear. The type and frequency of lubrication depend on the specific application and operating conditions.
Monitoring: Routine monitoring for signs of wear, noise, or overheating can help identify issues early and extend the bearing’s operational life.

The 29420 E spherical roller thrust bearing is a robust and effective solution for applications involving heavy axial loads. Its unique design features, including the spherical rollers and self-aligning capabilities, make it suitable for demanding operational environments, ensuring reliability and long service life in various industrial applications.
