Bearing Clearance
Clearance: radial clearance of deep groove ball bearings is manufactured according to GB/T4604-1999 (equivalent to ISO 5753-1991). In general, radial clearance of deep groove ball bearings is the basic group (group Co), and other group clearance can be used if customers request. The list of radial clearance of deep groove ball bearings is as follows.
