Product Overview: The 29418 Spherical Roller Thrust Bearing
The 29418 bearing is a high-performance component engineered to manage extreme operating conditions. As a vital part of our Spherical Roller Thrust Bearings collection, this bearing is specifically designed to accommodate very high axial (thrust) loads in one direction, while also being able to handle moderate radial loads. Its standard dimensions are 90mm bore diameter, 190mm outer diameter, and 60mm thickness. The key feature of the 29418, and all bearings in the 29400 Series, is its ability to self-align, compensating for shaft deflection and misalignment between the shaft and housing, which prevents edge stresses and extends service life.
Manufactured from high-purity, ultra-clean steel, this bearing offers exceptional durability and reliability in the most demanding industrial environments. The separable design, consisting of a shaft washer, a housing washer, and a roller-and-cage assembly, simplifies mounting and dismounting procedures, making it a practical choice for heavy machinery maintenance.
Key Features of the 29418 Bearing
- Exceptional Axial Load Capacity: Engineered to support heavy thrust loads, making it ideal for heavy-duty applications.
- Self-Aligning Capability: Features a spherical raceway in the housing washer that accommodates angular misalignment, reducing stress on the bearing.
- Separable Design: The components can be mounted individually, which simplifies the installation and inspection process.
- Robust Construction: Made from high-quality bearing steel to ensure long-lasting performance and resistance to wear and fatigue.
- Optimized Roller Design: The specially designed rollers distribute loads evenly across the raceways, minimizing friction and heat generation.
- High-Speed Performance: Suitable for applications requiring high rotational speeds under significant load.
Common Applications
- Industrial Gearboxes: Provides robust support for vertical shafts and manages the high thrust forces generated by helical gears.
- Pulp and Paper Machinery: Used in refiners, pulpers, and press sections where heavy loads and misalignment are common.
- Cranes and Hoists: Essential for crane hooks and swivels, safely managing massive suspended loads.
- Marine Propulsion Systems: Employed in ship propeller shafts and thrusters to handle immense axial forces.
- Extruders: Ideal for plastics and rubber extrusion machinery, supporting the extruder screw against high back pressure.
- Mining and Construction Equipment: Used in crushers, grinding mills, and drilling rigs that operate under severe conditions.
- Vertical Pumps and Motors: Provides reliable axial support for vertical shaft arrangements in large-scale fluid handling systems.
Benefits of Using the 29418 Bearing
- Enhanced Equipment Reliability: The ability to handle both heavy loads and misalignment significantly reduces the risk of premature failure and costly downtime.
- Extended Service Life: Superior materials and optimized internal geometry lead to a longer operational lifespan, even in harsh environments.
- Simplified Maintenance: The separable nature of the bearing allows for easier mounting, dismounting, and inspection, reducing maintenance time.
- Improved Operational Efficiency: Low-friction characteristics ensure smooth operation, contributing to better energy efficiency of the machinery.
- High Performance Under Stress: Maintains operational integrity under conditions of heavy load, shaft deflection, and potential misalignment.
- Versatile Application Range: Its robust design makes it suitable for a wide array of heavy industrial machinery across various sectors.
