Powerlong mininature ball bearing 60 series are comparatively small and have an inner diameter of 2 to 9 millimeters. Therefore they are suitable for relatively thin shafts and axis as well as for small space requirements. In the ratio of hybrid mininature deep groove ball bearings to its low size,they can take up relatively high loads.They are suitable for high up to extremely high rotational speeds.
Seals:
Rubber seals(RS/2RS) have the optimum sealing action with increased friction. Metal seals(z/zz) are suitable for high speeds, but they have a limited sealing action as they seal contactless. Open bearings are suitable for extremely high speeds and they can be regreased easily. But they are more susceptible to soiling.
