The self-aligning roller bearings of the vibrating screen have characteristics such as impact resistance, high load-bearing capacity, self centering, high precision, optimized heat dissipation, and long service life. The specific features are as follows:
Excellent impact resistance: The vibrating screen generates strong vibration and impact loads during operation, and the self-aligning roller bearings can withstand these impacts to ensure stable operation under harsh working conditions. Strong bearing capacity: mainly capable of bearing radial loads, but also capable of bearing axial loads in any direction, with high radial load capacity, especially suitable for working under heavy loads or vibration loads.
Automatic centering function: The inner ring axis can still operate normally when there is a significant inclination (usually within 3 degrees) relative to the outer ring axis.
. This allows the bearing to maintain good working condition even when there is a certain error in installation or deformation of the axis during operation, and can compensate for coaxiality errors. High precision tolerance control: The dimensional tolerance is generally P6, and the operating tolerance is P5, ensuring high-precision operation of the bearing, reducing vibration and noise, and improving the overall performance of the equipment.Heat dissipation optimization design: Due to the large amount of heat generated during the operation of the vibrating screen, the self-aligning roller bearing has chosen a large clearance design.
. This clearance can be calculated, mainly considering factors such as the original clearance, tolerance fit, and temperature rise, which helps the bearing dissipate heat better and reduce temperature rise during operation.Excellent Material and Craftsmanship:
Material Selection: The application requirements for vibrating screen bearings are very high, and ordinary bearing steel materials cannot meet the needs.
. The inner and outer rings and rolling elements are often made of vacuum degassed bearing steel, which has good fatigue resistance; The retaining frame is made of machined brass or aluminum iron manganese bronze material, which has high strength, high elasticity, and good wear resistance.Process optimization: Strive for excellence in the process, such as increasing the length and diameter of rolling elements, and designing oil grooves and holes on the outer diameter to enhance lubrication effect;
; The cage is guided by the outer ring edge to reduce the force on the rollers and improve their operation.Long life and high reliability: The self-aligning roller bearings of vibrating screens have the characteristics of low noise, low temperature rise, good stability, and long service life. There is no early fatigue phenomenon, and they can operate stably for a long time, reducing equipment downtime and maintenance costs.
