Instruction to utility of 6221ZZ deep groove ball bearing

 Considering the limited self-aligning role, 6221ZZ deep groove ball bearings require good concentricity for the installation seat. Otherwise the balance during the operation will be harmed. 6221ZZ deep groove ball bearings only allow a small deflection angle, which is also influenced by the load mounted on the bearing.
