Self aligning ball bearings are a type of rolling bearing with a spherical outer raceway, which has automatic centering function and can compensate for errors caused by shaft deflection or non concentric support holes. It allows the relative inclination of the inner and outer rings to not exceed 3 degrees
Load capacity: mainly capable of bearing radial loads, can withstand smaller axial loads, but not suitable for pure axial working conditions
Speed limit: 6200r/min under grease lubrication, 8600r/min under oil lubrication
Temperature range: Suitable for -30 ℃ to+120 ℃, with pre filled lubricating grease for sealing ring models, no need to clean before installation
Application field
Industrial equipment: paper making machinery, textile machinery, mining equipment, automotive transmission shafts, etc
Medical field: such as KOYO 2308 bearings used in diagnostic equipment, traction correction equipment
Advantages and limitations
Advantages: Automatic centering reduces installation accuracy requirements, low friction coefficient, suitable for high-speed scenarios.
Limitation: Tilt angle exceeding 3 degrees will affect the service life, and CA type structure with dual gear edges should be selected for heavy-duty environments
