Product Overview: The 21305 Spherical Roller Bearing
The 21305 Spherical Roller Bearing is a high-capacity, self-aligning bearing designed for the most demanding industrial applications. With dimensions of 25x52x18mm, this bearing is a key component in our 21300 Series, part of the broader Spherical Roller Bearings collection. Its robust construction features two rows of symmetrical barrel rollers and a common sphered outer ring raceway, enabling it to accommodate heavy radial loads, axial loads in both directions, and significant shaft misalignment or deflection. This design ensures reliable performance and longevity even under severe operating conditions, making it an essential part for heavy machinery.
Key Features of the 21305 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment between the shaft and housing, reducing stress on the bearing and extending equipment life.
- High Load Capacity: Engineered to handle substantial radial and axial loads, making it suitable for heavy-duty applications.
- Double Row Roller Design: Features two rows of barrel-shaped rollers for maximum load distribution and operational stability.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and performance in harsh environments.
- Precision Engineering: Produced to strict industry standards to ensure dimensional accuracy and consistent, reliable operation.
- Enhanced Durability: Designed to perform under conditions of high shock loads and vibration without compromising service life.
Common Applications
- Mining and Construction: Used in crushers, vibrating screens, conveyor systems, and heavy earth-moving equipment.
- Pulp and Paper Mills: Ideal for paper machines, calendars, and other processing equipment where heavy loads and misalignment are common.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale transmission systems.
- Metal Processing: Employed in rolling mills, continuous casting machines, and other steel manufacturing equipment.
- Wind Turbines: Essential for main shafts and gearboxes in wind energy generation systems.
- Agricultural Machinery: Suitable for heavy-duty equipment like combines and large tractors that operate in challenging conditions.
- Marine and Offshore: Used in propulsion systems, winches, and cranes where reliability is critical.
Benefits of Using the 21305 Bearing
- Increased Machine Uptime: The bearing's ability to handle heavy loads and misalignment reduces the risk of premature failure and costly downtime.
- Extended Service Life: Robust design and premium materials ensure a long operational lifespan, even under extreme stress.
- Lower Maintenance Costs: High reliability and durability lead to less frequent need for replacement and maintenance interventions.
- Improved Operational Efficiency: The low-friction design of the rollers and raceways helps minimize energy loss and heat generation.
- Versatile Performance: Capable of operating effectively across a wide range of speeds and environmental conditions.
- Simplified Assembly: The self-aligning feature can simplify the design and assembly of machinery by relaxing the tolerance requirements for shaft and housing alignment.
