Product Overview: The 21319 Spherical Roller Bearing
The 21319 Spherical Roller Bearing is a high-performance component engineered for the most demanding industrial applications. With key dimensions of 95x200x45mm (Bore x Outer Diameter x Thickness), this bearing is part of our robust 21300 Series within the broader Spherical Roller Bearings category. Its design features two rows of symmetrical barrel rollers and a common sphered raceway in the outer ring. This unique construction allows the bearing to accommodate significant angular misalignment of the shaft relative to the housing, making it indispensable in machinery where shaft deflection or mounting errors are a concern.
Built to handle very heavy radial and axial loads in both directions, the 21319 bearing provides exceptional reliability and a long service life. It is a critical component in heavy machinery, ensuring smooth operation and stability under extreme conditions and high shock loads. We supply industry-standard spherical roller bearings that guarantee performance and durability for your operational success.
Key Features of the 21319 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment and shaft deflection, reducing stress on the bearing and extending machine life.
- High Load-Carrying Capacity: Engineered with two rows of rollers to support very high radial loads and substantial axial loads in both directions.
- Robust Construction: Manufactured from high-quality bearing steel for superior strength, durability, and resistance to wear and fatigue.
- Optimized Internal Design: Features a design that minimizes friction and heat generation, ensuring efficient and cool operation even at high speeds.
- Dimensional Stability: Precision-engineered to maintain its dimensions under heavy loads and varying temperatures, ensuring consistent performance.
- Versatile Mounting Options: Typically available with a cylindrical or tapered bore (for use with adapter sleeves like the H 219) to suit different mounting requirements.
Common Applications of 21319 Bearings
- Mining and Construction: Used in heavy-duty equipment such as rock crushers, vibrating screens, and conveyor systems where high loads and misalignment are common.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale transmission systems.
- Pulp and Paper Mills: Essential for the rollers and machinery used in paper production, which operate in harsh, wet environments.
- Steel Manufacturing: Employed in rolling mills, continuous casters, and other machinery exposed to extreme temperatures and loads.
- Wind Turbines: Supports the main shaft and gearbox components, withstanding fluctuating loads and operational stresses.
- Marine Propulsion Systems: Used in propeller shafts and related equipment, offering reliability in demanding marine conditions.
- Agricultural Machinery: Suitable for heavy farming equipment that operates on uneven terrain, causing shaft deflection.
Benefits of Using the 21319 Bearing
- Increased Machine Uptime: The bearing's ability to handle misalignment and heavy loads reduces the likelihood of premature failure and costly downtime.
- Enhanced Operational Reliability: Provides stable and predictable performance in harsh environments, contributing to overall system safety and efficiency.
- Reduced Maintenance Costs: The durable design and self-aligning properties lead to a longer service life and fewer maintenance interventions.
- Improved Performance under Load: Maintains smooth operation without excessive heat or friction, even under the heaviest radial and axial forces.
- Simplified Assembly: The self-aligning feature can simplify the mounting process, as it is more forgiving of initial alignment errors.
- Versatility Across Industries: Its robust characteristics make it an ideal choice for a wide range of heavy industrial applications, from mining to energy generation.
