231 series

The 231 series is a heavy-duty version of self-aligning roller bearings that combines high load capacity and high speed. It adopts a double row spherical roller structure and optimizes the structure ratio of the raceway and rollers based on the 230 series. It has strong radial load capacity and is suitable for heavy-duty working conditions from medium low speed to medium high speed. It is the main supporting bearing for large equipment such as metallurgy, wind power, and heavy machinery, with a wider adaptability than the 230 series.
