Product Overview: The 21314 Spherical Roller Bearing
The 21314 Spherical Roller Bearing is a high-capacity component engineered for the most demanding industrial applications. With core dimensions of 70mm Bore Diameter, 150mm Outer Diameter, and 35mm Thickness, this bearing is part of our robust 21300 Series. It is specifically designed to handle very heavy radial loads and significant axial loads in both directions. The key feature of this bearing is its ability to accommodate misalignment between the shaft and housing, which can be caused by shaft deflection or mounting errors. Its internal design, featuring two rows of symmetrical barrel rollers and a common sphered raceway in the outer ring, ensures optimal performance even under challenging conditions.
As a premier supplier of industrial components, we offer the 21314 bearing manufactured to strict quality standards. This makes it an essential part for heavy machinery where reliability and longevity are critical. Explore our full range of Spherical Roller Bearings to find the ideal solution for your heavy-duty operational needs.
Key Features of the 21314 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment, reducing stress on the shaft and extending the life of the machinery.
- High Load Capacity: The double-row roller design provides excellent capacity for both high radial and axial loads.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and long service life under heavy loads.
- Optimized Internal Geometry: Reduces friction and heat generation, leading to more efficient operation and lower energy consumption.
- Versatile Mounting: Available with a cylindrical or tapered bore, allowing for mounting with adapter or withdrawal sleeves on plain shafts.
- Dimensional Stability: Engineered to maintain its shape and performance even under high temperatures and harsh operating conditions.
Common Applications
- Mining and Construction: Widely used in crushers, vibrating screens, conveyors, and heavy earth-moving equipment.
- Pulp and Paper Mills: Essential for rollers and processing machinery that operate under heavy loads and in wet environments.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale transmission systems.
- Steel Manufacturing: Utilized in continuous casting machines, rolling mills, and other high-temperature, heavy-load applications.
- Wind Turbines: Supports the main shafts and gearboxes, withstanding fluctuating loads and harsh weather conditions.
- Marine and Offshore: Applied in propulsion systems, winches, and cranes where reliability is paramount.
- Large Fans and Blowers: Accommodates potential shaft deflection in industrial ventilation systems.
