Spherical roller bearings are bearings that can withstand large radial and certain axial loads. They have an outer ring with an inner spherical surface, and the inner ring can tilt to form a certain angle with the roller component, allowing for deviation between the shaft and the seat ring. This self-aligning design allows self-aligning roller bearings to adapt to situations where the shaft and race are not completely aligned or have slight deviations, thereby reducing stress and friction, and extending the lifespan of the bearings.
The main characteristics of self-aligning roller bearings include:
1. Strong bearing capacity: Self aligning roller bearings have a large radial load bearing capacity and can withstand higher loads.
2. Strong adaptability: Due to its self-aligning design, self-aligning roller bearings can automatically adjust the deviation between the shaft and race, adapt to eccentric loads and axial displacement, and enable the bearings to work normally under vibration and deflection conditions.
3. Good impact resistance: The design of the self-aligning roller bearing adopts larger rollers and inner and outer ring spherical surfaces, which improves its impact resistance and ability to withstand impact loads.
4. High speed operation: Through optimized design and processing, self-aligning roller bearings can operate at higher speeds.
5. Good high-temperature resistance: Self aligning roller bearings usually use materials and special heat treatment, which can work normally in high-temperature environments.
Self aligning roller bearings are widely used in industries such as heavy machinery equipment, metallurgy, mining, petroleum, chemical engineering, and papermaking. Common applications include excavators, steel mills, cement equipment, roller conveyors, and centrifuges. When selecting self-aligning roller bearings, it is necessary to consider factors such as load type, speed requirements, operating temperature, and installation conditions to ensure correct matching and meet application requirements.
