Spherical Roller Bearings
Spherical Roller Bearings are a type of Rolling Bearing commonly used in industrial applications. They are designed to allow rotation with low friction and accommodate angular misalignment between the shaft and housing. These bearings are known for their ability to handle heavy loads, both radial and axial, and provide smoother rotation compared to other bearing types.
Construction and Design:
Spherical roller bearings have one or two rows of barrel-shaped rollers positioned at an angle to the bearing axis [3].
The outer ring has a spherical surface, allowing the rollers to move sideways, while the inner ring has raceways for the rollers to move along [3].
A cage holds the rollers in place, and the rollers themselves have a spherical contact surface with a curvature that enables the bearing to handle axial loads [3].
Benefits and Advantages:
1. Reduced friction and smoother rotation: Spherical roller bearings minimize friction, resulting in smoother rotation.
2. Angular misalignment accommodation: These bearings can accommodate misalignment between the shaft and housing, making them suitable for applications prone to misalignment or shaft deflection.
3. High load carrying capacity: Spherical roller bearings have an outstanding load carrying capacity for radial and combination loads in one direction due to their design with multiple spherical rollers.
4. Moderate to high-speed capability: These bearings are capable of operating at moderate to high speeds.
5. Reduced maintenance requirements: Spherical roller bearings have reduced maintenance requirements, contributing to their extended service life.
6. Reduced noise and vibration levels: These bearings offer reduced noise and vibration levels during operation.
Industrial Applications:
Mining equipment: Spherical roller bearings are commonly used in mining equipment, supporting components such as conveyor pulleys or crusher shafts that experience large forces during the extraction process.
