Deep groove Radial ball bearings
Selection Guide
GMN radial deep groove radial ball bearings are available in a wide range of executions. For technical reasons, not every basic type can be supplied with every special feature, e.g. combining TB- cage with shields is not possible for most basic types.
Hence there is no online selection available. Below we have listed our designation system and a listing of our basic types. For support or bearing selection please contact our application engineers.
