Note: This bearing has low cost, large bearing capacity, and is suitable for supporting structures with limited installation size. The journal surface is hardened as a rolling surface, and the bearing is pressed into the seat hole without axial positioning. Bearings should be injected into the appropriate amount of grease before installation, under normal circumstances, after the assembly does not need to lubricate the BK bearing used in the support of the journal without an extended end, the end face closure plays a sealing role, and can withstand small axial swimming power.
