239 series

The 239 series is a super large narrow width heavy-duty bearing in the field of self-aligning roller bearings. It adopts a double row spherical roller+outer ring spherical raceway structure, focusing on large inner diameter, compact width, and high rigidity. Under the same inner diameter, the width is narrower than that of the 230/231/232 series, suitable for heavy low-speed working conditions with large shaft diameter and limited installation space. It is a compact heavy-duty support solution for large rotating equipment and widely used in metallurgy, wind power, heavy-duty machine tools and other fields.
