Miniature Bearings 604
Miniature Bearings 604

Among all ultra small aperture bearings,the miniature deep groove ball bearing include 68 series, 69 series, 60 series, and  inch R series. Based on this, also can be divided into ZZ steel bearing shield series, with RS rubber sealing ring micro bearing series, Teflon bearing seal ring series and flange flange series and so on.

Feature: Miniature bearing are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance.Deep-groove bearings have higher load ratings for their size than shallow-groove , but are also less tolerant of misalignment of the inner and outer races

Application:Miniature bearing suitable for precision instrument, low noise electromotor, automobile and motorcycle, etc. It is the the most widely used bearing type.
