Structural improvement of four-row cylindrical roller bearings

When the rolling mill rolls are supported by four-row cylindrical roller bearings, their structure is mainly determined based on the JB/T5389.11995 standard. During long-term use, it was found that the cage of the bearing was easily deformed during the assembly of the finished product, causing premature failure of the bearing during operation. Therefore, taking the […]
